8
+ Thanks a lot for taking the time to file this issue 🤗.
9
+ Issues do not only help to improve the library, but also publicly document common problems, questions, workflows for the whole community!
10
+ Thus, issues are of the same importance as pull requests when contributing to this library ❤️.
11
+ In order to make your issue as **useful for the community as possible**, let's try to stick to some simple guidelines:
12
+ - 1. Please try to be as precise and concise as possible.
13
+ *Give your issue a fitting title. Assume that someone which very limited knowledge of Diffusers can understand your issue. Add links to the source code, documentation other issues, pull requests etc...*
14
+ - 2. If your issue is about something not working, **always** provide a reproducible code snippet. The reader should be able to reproduce your issue by **only copy-pasting your code snippet into a Python shell**.
15
+ *The community cannot solve your issue if it cannot reproduce it. If your bug is related to training, add your training script and make everything needed to train public. Otherwise, just add a simple Python code snippet.*
16
+ - 3. Add the **minimum** amount of code / context that is needed to understand, reproduce your issue.
17
+ *Make the life of maintainers easy. `diffusers` is getting many issues every day. Make sure your issue is about one bug and one bug only. Make sure you add only the context, code needed to understand your issues - nothing more. Generally, every issue is a way of documenting this library, try to make it a good documentation entry.*
18
+ - 4. For issues related to community pipelines (i.e., the pipelines located in the `examples/community` folder), please tag the author of the pipeline in your issue thread as those pipelines are not maintained.

+ Your issue will be replied to more quickly if you can figure out the right person to tag with @.
59
+ If you know how to use git blame, that is the easiest way, otherwise, here is a rough guide of **who to tag**.
60
+
61
+ All issues are read by one of the core maintainers, so if you don't know who to tag, just leave this blank and
62
+ a core maintainer will ping the right person.
63

64

+ # Contributor Covenant Code of Conduct
3
+
4
+ ## Our Pledge
5
+
6
+ We as members, contributors, and leaders pledge to make participation in our
7
+ community a harassment-free experience for everyone, regardless of age, body
8
+ size, visible or invisible disability, ethnicity, sex characteristics, gender
9
+ identity and expression, level of experience, education, socio-economic status,
10
+ nationality, personal appearance, race, caste, color, religion, or sexual identity
11
+ and orientation.
12
+
13
+ We pledge to act and interact in ways that contribute to an open, welcoming,
14
+ diverse, inclusive, and healthy community.
15
+
16
+ ## Our Standards
17
+
18
+ Examples of behavior that contributes to a positive environment for our
19
+ community include:
20
+
21
+ * Demonstrating empathy and kindness toward other people
22
+ * Being respectful of differing opinions, viewpoints, and experiences
23
+ * Giving and gracefully accepting constructive feedback
24
+ * Accepting responsibility and apologizing to those affected by our mistakes,
25
+ and learning from the experience
26
+ * Focusing on what is best not just for us as individuals, but for the
27
+ overall Diffusers community
28
+
29
+ Examples of unacceptable behavior include:
30
+
31
+ * The use of sexualized language or imagery, and sexual attention or
32
+ advances of any kind
33
+ * Trolling, insulting or derogatory comments, and personal or political attacks
34
+ * Public or private harassment
35
+ * Publishing others' private information, such as a physical or email
36
+ address, without their explicit permission
37
+ * Spamming issues or PRs with links to projects unrelated to this library
38
+ * Other conduct which could reasonably be considered inappropriate in a
39
+ professional setting
40
+
41
+ ## Enforcement Responsibilities
42
+
43
+ Community leaders are responsible for clarifying and enforcing our standards of
44
+ acceptable behavior and will take appropriate and fair corrective action in
45
+ response to any behavior that they deem inappropriate, threatening, offensive,
46
+ or harmful.
47
+
48
+ Community leaders have the right and responsibility to remove, edit, or reject
49
+ comments, commits, code, wiki edits, issues, and other contributions that are
50
+ not aligned to this Code of Conduct, and will communicate reasons for moderation
51
+ decisions when appropriate.
52
+
53
+ ## Scope
54
+
55
+ This Code of Conduct applies within all community spaces, and also applies when
56
+ an individual is officially representing the community in public spaces.
57
+ Examples of representing our community include using an official e-mail address,
58
+ posting via an official social media account, or acting as an appointed
59
+ representative at an online or offline event.
60
+
61
+ ## Enforcement
62
+
63
+ Instances of abusive, harassing, or otherwise unacceptable behavior may be
64
+ reported to the community leaders responsible for enforcement at
65
+ feedback@huggingface.co.
66
+ All complaints will be reviewed and investigated promptly and fairly.
67
+
68
+ All community leaders are obligated to respect the privacy and security of the
69
+ reporter of any incident.
70
+
71
+ ## Enforcement Guidelines
72
+
73
+ Community leaders will follow these Community Impact Guidelines in determining
74
+ the consequences for any action they deem in violation of this Code of Conduct:
75
+
76
+ ### 1. Correction
77
+
78
+ **Community Impact**: Use of inappropriate language or other behavior deemed
79
+ unprofessional or unwelcome in the community.
80
+
81
+ **Consequence**: A private, written warning from community leaders, providing
82
+ clarity around the nature of the violation and an explanation of why the
83
+ behavior was inappropriate. A public apology may be requested.
84
+
85
+ ### 2. Warning
86
+
87
+ **Community Impact**: A violation through a single incident or series
88
+ of actions.
89
+
90
+ **Consequence**: A warning with consequences for continued behavior. No
91
+ interaction with the people involved, including unsolicited interaction with
92
+ those enforcing the Code of Conduct, for a specified period of time. This
93
+ includes avoiding interactions in community spaces as well as external channels
94
+ like social media. Violating these terms may lead to a temporary or
95
+ permanent ban.
96
+
97
+ ### 3. Temporary Ban
98
+
99
+ **Community Impact**: A serious violation of community standards, including
100
+ sustained inappropriate behavior.
101
+
102
+ **Consequence**: A temporary ban from any sort of interaction or public
103
+ communication with the community for a specified period of time. No public or
104
+ private interaction with the people involved, including unsolicited interaction
105
+ with those enforcing the Code of Conduct, is allowed during this period.
106
+ Violating these terms may lead to a permanent ban.
107
+
108
+ ### 4. Permanent Ban
109
+
110
+ **Community Impact**: Demonstrating a pattern of violation of community
111
+ standards, including sustained inappropriate behavior, harassment of an
112
+ individual, or aggression toward or disparagement of classes of individuals.
113
+
114
+ **Consequence**: A permanent ban from any sort of public interaction within
115
+ the community.

+ # How to contribute to Diffusers 🧨
14
+
15
+ We ❤️ contributions from the open-source community! Everyone is welcome, and all types of participation –not just code– are valued and appreciated. Answering questions, helping others, reaching out, and improving the documentation are all immensely valuable to the community, so don't be afraid and get involved if you're up for it!
16
+
17
+ Everyone is encouraged to start by saying 👋 in our public Discord channel. We discuss the latest trends in diffusion models, ask questions, show off personal projects, help each other with contributions, or just hang out ☕. <a href="https://discord.gg/G7tWnz98XR"><img alt="Join us on Discord" src="https://img.shields.io/discord/823813159592001537?color=5865F2&logo=Discord&logoColor=white"></a>
18
+
19
+ Whichever way you choose to contribute, we strive to be part of an open, welcoming, and kind community. Please, read our [code of conduct](https://github.com/huggingface/diffusers/blob/main/CODE_OF_CONDUCT.md) and be mindful to respect it during your interactions. We also recommend you become familiar with the [ethical guidelines](https://huggingface.co/docs/diffusers/conceptual/ethical_guidelines) that guide our project and ask you to adhere to the same principles of transparency and responsibility.
20
+
21
+ We enormously value feedback from the community, so please do not be afraid to speak up if you believe you have valuable feedback that can help improve the library - every message, comment, issue, and pull request (PR) is read and considered.
22
+
23
+ ## Overview
24
+
25
+ You can contribute in many ways ranging from answering questions on issues to adding new diffusion models to
26
+ the core library.
27
+
28
+ In the following, we give an overview of different ways to contribute, ranked by difficulty in ascending order. All of them are valuable to the community.
29
+
30
+ * 1. Asking and answering questions on [the Diffusers discussion forum](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers) or on [Discord](https://discord.gg/G7tWnz98XR).
31
+ * 2. Opening new issues on [the GitHub Issues tab](https://github.com/huggingface/diffusers/issues/new/choose).
32
+ * 3. Answering issues on [the GitHub Issues tab](https://github.com/huggingface/diffusers/issues).
33
+ * 4. Fix a simple issue, marked by the "Good first issue" label, see [here](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22).
34
+ * 5. Contribute to the [documentation](https://github.com/huggingface/diffusers/tree/main/docs/source).
35
+ * 6. Contribute a [Community Pipeline](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3Acommunity-examples).
36
+ * 7. Contribute to the [examples](https://github.com/huggingface/diffusers/tree/main/examples).
37
+ * 8. Fix a more difficult issue, marked by the "Good second issue" label, see [here](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22Good+second+issue%22).
38
+ * 9. Add a new pipeline, model, or scheduler, see ["New Pipeline/Model"](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+pipeline%2Fmodel%22) and ["New scheduler"](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+scheduler%22) issues. For this contribution, please have a look at [Design Philosophy](https://github.com/huggingface/diffusers/blob/main/PHILOSOPHY.md).
39
+
40
+ As said before, **all contributions are valuable to the community**.
41
+ In the following, we will explain each contribution a bit more in detail.
42
+
43
+ For all contributions 4-9, you will need to open a PR. It is explained in detail how to do so in [Opening a pull request](#how-to-open-a-pr).
44
+
45
+ ### 1. Asking and answering questions on the Diffusers discussion forum or on the Diffusers Discord
46
+
47
+ Any question or comment related to the Diffusers library can be asked on the [discussion forum](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers/) or on [Discord](https://discord.gg/G7tWnz98XR). Such questions and comments include (but are not limited to):
48
+ - Reports of training or inference experiments in an attempt to share knowledge
49
+ - Presentation of personal projects
50
+ - Questions to non-official training examples
51
+ - Project proposals
52
+ - General feedback
53
+ - Paper summaries
54
+ - Asking for help on personal projects that build on top of the Diffusers library
55
+ - General questions
56
+ - Ethical questions regarding diffusion models
57
+ - ...
58
+
59
+ Every question that is asked on the forum or on Discord actively encourages the community to publicly
60
+ share knowledge and might very well help a beginner in the future who has the same question you're
61
+ having. Please do pose any questions you might have.
62
+ In the same spirit, you are of immense help to the community by answering such questions because this way you are publicly documenting knowledge for everybody to learn from.
63
+
64
+ **Please** keep in mind that the more effort you put into asking or answering a question, the higher
65
+ the quality of the publicly documented knowledge. In the same way, well-posed and well-answered questions create a high-quality knowledge database accessible to everybody, while badly posed questions or answers reduce the overall quality of the public knowledge database.
66
+ In short, a high quality question or answer is *precise*, *concise*, *relevant*, *easy-to-understand*, *accessible*, and *well-formatted/well-posed*. For more information, please have a look through the [How to write a good issue](#how-to-write-a-good-issue) section.
67
+
68
+ **NOTE about channels**:
69
+ [*The forum*](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers/63) is much better indexed by search engines, such as Google. Posts are ranked by popularity rather than chronologically. Hence, it's easier to look up questions and answers that we posted some time ago.
70
+ In addition, questions and answers posted in the forum can easily be linked to.
71
+ In contrast, *Discord* has a chat-like format that invites fast back-and-forth communication.
72
+ While it will most likely take less time for you to get an answer to your question on Discord, your
73
+ question won't be visible anymore over time. Also, it's much harder to find information that was posted a while back on Discord. We therefore strongly recommend using the forum for high-quality questions and answers in an attempt to create long-lasting knowledge for the community. If discussions on Discord lead to very interesting answers and conclusions, we recommend posting the results on the forum to make the information more available for future readers.
74
+
75
+ ### 2. Opening new issues on the GitHub issues tab
76
+
77
+ The 🧨 Diffusers library is robust and reliable thanks to the users who notify us of
78
+ the problems they encounter. So thank you for reporting an issue.
79
+
80
+ Remember, GitHub issues are reserved for technical questions directly related to the Diffusers library, bug reports, feature requests, or feedback on the library design.
81
+
82
+ In a nutshell, this means that everything that is **not** related to the **code of the Diffusers library** (including the documentation) should **not** be asked on GitHub, but rather on either the [forum](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers/63) or [Discord](https://discord.gg/G7tWnz98XR).
83
+
84
+ **Please consider the following guidelines when opening a new issue**:
85
+ - Make sure you have searched whether your issue has already been asked before (use the search bar on GitHub under Issues).
86
+ - Please never report a new issue on another (related) issue. If another issue is highly related, please
87
+ open a new issue nevertheless and link to the related issue.
88
+ - Make sure your issue is written in English. Please use one of the great, free online translation services, such as [DeepL](https://www.deepl.com/translator) to translate from your native language to English if you are not comfortable in English.
89
+ - Check whether your issue might be solved by updating to the newest Diffusers version. Before posting your issue, please make sure that `python -c "import diffusers; print(diffusers.__version__)"` is higher or matches the latest Diffusers version.
90
+ - Remember that the more effort you put into opening a new issue, the higher the quality of your answer will be and the better the overall quality of the Diffusers issues.
91
+
92
+ New issues usually include the following.
93
+
94
+ #### 2.1. Reproducible, minimal bug reports
95
+
96
+ A bug report should always have a reproducible code snippet and be as minimal and concise as possible.
97
+ This means in more detail:
98
+ - Narrow the bug down as much as you can, **do not just dump your whole code file**.
99
+ - Format your code.
100
+ - Do not include any external libraries except for Diffusers depending on them.
101
+ - **Always** provide all necessary information about your environment; for this, you can run: `diffusers-cli env` in your shell and copy-paste the displayed information to the issue.
102
+ - Explain the issue. If the reader doesn't know what the issue is and why it is an issue, she cannot solve it.
103
+ - **Always** make sure the reader can reproduce your issue with as little effort as possible. If your code snippet cannot be run because of missing libraries or undefined variables, the reader cannot help you. Make sure your reproducible code snippet is as minimal as possible and can be copy-pasted into a simple Python shell.
104
+ - If in order to reproduce your issue a model and/or dataset is required, make sure the reader has access to that model or dataset. You can always upload your model or dataset to the [Hub](https://huggingface.co) to make it easily downloadable. Try to keep your model and dataset as small as possible, to make the reproduction of your issue as effortless as possible.
105
+
106
+ For more information, please have a look through the [How to write a good issue](#how-to-write-a-good-issue) section.
107
+
108
+ You can open a bug report [here](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=bug&projects=&template=bug-report.yml).
109
+
110
+ #### 2.2. Feature requests

+ A world-class feature request addresses the following points:
113
+
114
+ 1. Motivation first:
115
+ * Is it related to a problem/frustration with the library? If so, please explain
116
+ why. Providing a code snippet that demonstrates the problem is best.
117
+ * Is it related to something you would need for a project? We'd love to hear
118
+ about it!
119
+ * Is it something you worked on and think could benefit the community?
120
+ Awesome! Tell us what problem it solved for you.
121
+ 2. Write a *full paragraph* describing the feature;
122
+ 3. Provide a **code snippet** that demonstrates its future use;
123
+ 4. In case this is related to a paper, please attach a link;
124
+ 5. Attach any additional information (drawings, screenshots, etc.) you think may help.
125
+
126
+ You can open a feature request [here](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=&template=feature_request.md&title=).
127
+
128
+ #### 2.3 Feedback
129
+
130
+ Feedback about the library design and why it is good or not good helps the core maintainers immensely to build a user-friendly library. To understand the philosophy behind the current design philosophy, please have a look [here](https://huggingface.co/docs/diffusers/conceptual/philosophy). If you feel like a certain design choice does not fit with the current design philosophy, please explain why and how it should be changed. If a certain design choice follows the design philosophy too much, hence restricting use cases, explain why and how it should be changed.
131
+ If a certain design choice is very useful for you, please also leave a note as this is great feedback for future design decisions.
132
+
133
+ You can open an issue about feedback [here](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=&template=feedback.md&title=).
134
+
135
+ #### 2.4 Technical questions
136
+
137
+ Technical questions are mainly about why certain code of the library was written in a certain way, or what a certain part of the code does. Please make sure to link to the code in question and please provide detail on
138
+ why this part of the code is difficult to understand.
139
+
140
+ You can open an issue about a technical question [here](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=bug&template=bug-report.yml).
141
+
142
+ #### 2.5 Proposal to add a new model, scheduler, or pipeline
143
+
144
+ If the diffusion model community released a new model, pipeline, or scheduler that you would like to see in the Diffusers library, please provide the following information:
145
+
146
+ * Short description of the diffusion pipeline, model, or scheduler and link to the paper or public release.
147
+ * Link to any of its open-source implementation.
148
+ * Link to the model weights if they are available.
149
+
150
+ If you are willing to contribute to the model yourself, let us know so we can best guide you. Also, don't forget
151
+ to tag the original author of the component (model, scheduler, pipeline, etc.) by GitHub handle if you can find it.
152
+
153
+ You can open a request for a model/pipeline/scheduler [here](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=New+model%2Fpipeline%2Fscheduler&template=new-model-addition.yml).
154
+
155
+ ### 3. Answering issues on the GitHub issues tab
156
+
157
+ Answering issues on GitHub might require some technical knowledge of Diffusers, but we encourage everybody to give it a try even if you are not 100% certain that your answer is correct.
158
+ Some tips to give a high-quality answer to an issue:
159
+ - Be as concise and minimal as possible.
160
+ - Stay on topic. An answer to the issue should concern the issue and only the issue.
161
+ - Provide links to code, papers, or other sources that prove or encourage your point.
162
+ - Answer in code. If a simple code snippet is the answer to the issue or shows how the issue can be solved, please provide a fully reproducible code snippet.
163
+
164
+ Also, many issues tend to be simply off-topic, duplicates of other issues, or irrelevant. It is of great
165
+ help to the maintainers if you can answer such issues, encouraging the author of the issue to be
166
+ more precise, provide the link to a duplicated issue or redirect them to [the forum](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers/63) or [Discord](https://discord.gg/G7tWnz98XR).
167
+
168
+ If you have verified that the issued bug report is correct and requires a correction in the source code,
169
+ please have a look at the next sections.
170
+
171
+ For all of the following contributions, you will need to open a PR. It is explained in detail how to do so in the [Opening a pull request](#how-to-open-a-pr) section.
172
+
173
+ ### 4. Fixing a "Good first issue"
174
+
175
+ *Good first issues* are marked by the [Good first issue](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22) label. Usually, the issue already
176
+ explains how a potential solution should look so that it is easier to fix.
177
+ If the issue hasn't been closed and you would like to try to fix this issue, you can just leave a message "I would like to try this issue.". There are usually three scenarios:
178
+ - a.) The issue description already proposes a fix. In this case and if the solution makes sense to you, you can open a PR or draft PR to fix it.
179
+ - b.) The issue description does not propose a fix. In this case, you can ask what a proposed fix could look like and someone from the Diffusers team should answer shortly. If you have a good idea of how to fix it, feel free to directly open a PR.
180
+ - c.) There is already an open PR to fix the issue, but the issue hasn't been closed yet. If the PR has gone stale, you can simply open a new PR and link to the stale PR. PRs often go stale if the original contributor who wanted to fix the issue suddenly cannot find the time anymore to proceed. This often happens in open-source and is very normal. In this case, the community will be very happy if you give it a new try and leverage the knowledge of the existing PR. If there is already a PR and it is active, you can help the author by giving suggestions, reviewing the PR or even asking whether you can contribute to the PR.
181
+
182
+
183
+ ### 5. Contribute to the documentation
184
+
185
+ A good library **always** has good documentation! The official documentation is often one of the first points of contact for new users of the library, and therefore contributing to the documentation is a **highly
186
+ valuable contribution**.
187
+
188
+ Contributing to the library can have many forms:
189
+
190
+ - Correcting spelling or grammatical errors.
191
+ - Correct incorrect formatting of the docstring. If you see that the official documentation is weirdly displayed or a link is broken, we are very happy if you take some time to correct it.
192
+ - Correct the shape or dimensions of a docstring input or output tensor.
193
+ - Clarify documentation that is hard to understand or incorrect.
194
+ - Update outdated code examples.
195
+ - Translating the documentation to another language.
196
+
197
+ Anything displayed on [the official Diffusers doc page](https://huggingface.co/docs/diffusers/index) is part of the official documentation and can be corrected, adjusted in the respective [documentation source](https://github.com/huggingface/diffusers/tree/main/docs/source).
198
+
199
+ Please have a look at [this page](https://github.com/huggingface/diffusers/tree/main/docs) on how to verify changes made to the documentation locally.
200
+
201
+
202
+ ### 6. Contribute a community pipeline
203
+
204
+ [Pipelines](https://huggingface.co/docs/diffusers/api/pipelines/overview) are usually the first point of contact between the Diffusers library and the user.
205
+ Pipelines are examples of how to use Diffusers [models](https://huggingface.co/docs/diffusers/api/models/overview) and [schedulers](https://huggingface.co/docs/diffusers/api/schedulers/overview).
206
+ We support two types of pipelines:
207
+
208
+ - Official Pipelines
209
+ - Community Pipelines
210
+
211
+ Both official and community pipelines follow the same design and consist of the same type of components.
212
+
213
+ Official pipelines are tested and maintained by the core maintainers of Diffusers. Their code
214
+ resides in [src/diffusers/pipelines](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines).
215
+ In contrast, community pipelines are contributed and maintained purely by the **community** and are **not** tested.
216
+ They reside in [examples/community](https://github.com/huggingface/diffusers/tree/main/examples/community) and while they can be accessed via the [PyPI diffusers package](https://pypi.org/project/diffusers/), their code is not part of the PyPI distribution.
217
+
218
+ The reason for the distinction is that the core maintainers of the Diffusers library cannot maintain and test all
219
+ possible ways diffusion models can be used for inference, but some of them may be of interest to the community.
220
+ Officially released diffusion pipelines,
221
+ such as Stable Diffusion are added to the core src/diffusers/pipelines package which ensures
222
+ high quality of maintenance, no backward-breaking code changes, and testing.
223
+ More bleeding edge pipelines should be added as community pipelines. If usage for a community pipeline is high, the pipeline can be moved to the official pipelines upon request from the community. This is one of the ways we strive to be a community-driven library.
224
+
225
+ To add a community pipeline, one should add a <name-of-the-community>.py file to [examples/community](https://github.com/huggingface/diffusers/tree/main/examples/community) and adapt the [examples/community/README.md](https://github.com/huggingface/diffusers/tree/main/examples/community/README.md) to include an example of the new pipeline.
226
+
227
+ An example can be seen [here](https://github.com/huggingface/diffusers/pull/2400).
228
+
229
+ Community pipeline PRs are only checked at a superficial level and ideally they should be maintained by their original authors.
230
+
231
+ Contributing a community pipeline is a great way to understand how Diffusers models and schedulers work. Having contributed a community pipeline is usually the first stepping stone to contributing an official pipeline to the
232
+ core package.
233
+
234
+ ### 7. Contribute to training examples
235
+
236
+ Diffusers examples are a collection of training scripts that reside in [examples](https://github.com/huggingface/diffusers/tree/main/examples).
237
+
238
+ We support two types of training examples:
239
+
240
+ - Official training examples
241
+ - Research training examples
242
+
243
+ Research training examples are located in [examples/research_projects](https://github.com/huggingface/diffusers/tree/main/examples/research_projects) whereas official training examples include all folders under [examples](https://github.com/huggingface/diffusers/tree/main/examples) except the `research_projects` and `community` folders.
244
+ The official training examples are maintained by the Diffusers' core maintainers whereas the research training examples are maintained by the community.
245
+ This is because of the same reasons put forward in [6. Contribute a community pipeline](#6-contribute-a-community-pipeline) for official pipelines vs. community pipelines: It is not feasible for the core maintainers to maintain all possible training methods for diffusion models.
246
+ If the Diffusers core maintainers and the community consider a certain training paradigm to be too experimental or not popular enough, the corresponding training code should be put in the `research_projects` folder and maintained by the author.
247
+
248
+ Both official training and research examples consist of a directory that contains one or more training scripts, a `requirements.txt` file, and a `README.md` file. In order for the user to make use of the
249
+ training examples, it is required to clone the repository:
250
+
251
+ ```bash
252
+ git clone https://github.com/huggingface/diffusers
253
+ ```
254
+
255
+ as well as to install all additional dependencies required for training:
256
+
257
+ ```bash
258
+ cd diffusers
259
+ pip install -r examples/<your-example-folder>/requirements.txt
260
+ ```
261
+
262
+ Therefore when adding an example, the `requirements.txt` file shall define all pip dependencies required for your training example so that once all those are installed, the user can run the example's training script. See, for example, the [DreamBooth `requirements.txt` file](https://github.com/huggingface/diffusers/blob/main/examples/dreambooth/requirements.txt).
263
+
264
+ Training examples of the Diffusers library should adhere to the following philosophy:
265
+ - All the code necessary to run the examples should be found in a single Python file.
266
+ - One should be able to run the example from the command line with `python <your-example>.py --args`.
267
+ - Examples should be kept simple and serve as **an example** on how to use Diffusers for training. The purpose of example scripts is **not** to create state-of-the-art diffusion models, but rather to reproduce known training schemes without adding too much custom logic. As a byproduct of this point, our examples also strive to serve as good educational materials.
268
+
269
+ To contribute an example, it is highly recommended to look at already existing examples such as [dreambooth](https://github.com/huggingface/diffusers/blob/main/examples/dreambooth/train_dreambooth.py) to get an idea of how they should look like.
270
+ We strongly advise contributors to make use of the [Accelerate library](https://github.com/huggingface/accelerate) as it's tightly integrated
271
+ with Diffusers.
272
+ Once an example script works, please make sure to add a comprehensive `README.md` that states how to use the example exactly. This README should include:
273
+ - An example command on how to run the example script as shown [here e.g.](https://github.com/huggingface/diffusers/tree/main/examples/dreambooth#running-locally-with-pytorch).
274
+ - A link to some training results (logs, models, ...) that show what the user can expect as shown [here e.g.](https://api.wandb.ai/report/patrickvonplaten/xm6cd5q5).
275
+ - If you are adding a non-official/research training example, **please don't forget** to add a sentence that you are maintaining this training example which includes your git handle as shown [here](https://github.com/huggingface/diffusers/tree/main/examples/research_projects/intel_opts#diffusers-examples-with-intel-optimizations).
276
+
277
+ If you are contributing to the official training examples, please also make sure to add a test to [examples/test_examples.py](https://github.com/huggingface/diffusers/blob/main/examples/test_examples.py). This is not necessary for non-official training examples.
278
+
279
+ ### 8. Fixing a "Good second issue"
280
+
281
+ *Good second issues* are marked by the [Good second issue](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22Good+second+issue%22) label. Good second issues are
282
+ usually more complicated to solve than [Good first issues](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22).
283
+ The issue description usually gives less guidance on how to fix the issue and requires
284
+ a decent understanding of the library by the interested contributor.
285
+ If you are interested in tackling a good second issue, feel free to open a PR to fix it and link the PR to the issue. If you see that a PR has already been opened for this issue but did not get merged, have a look to understand why it wasn't merged and try to open an improved PR.
286
+ Good second issues are usually more difficult to get merged compared to good first issues, so don't hesitate to ask for help from the core maintainers. If your PR is almost finished the core maintainers can also jump into your PR and commit to it in order to get it merged.
287
+
288
+ ### 9. Adding pipelines, models, schedulers
289
+
290
+ Pipelines, models, and schedulers are the most important pieces of the Diffusers library.
291
+ They provide easy access to state-of-the-art diffusion technologies and thus allow the community to
292
+ build powerful generative AI applications.
293
+
294
+ By adding a new model, pipeline, or scheduler you might enable a new powerful use case for any of the user interfaces relying on Diffusers which can be of immense value for the whole generative AI ecosystem.
295
+
296
+ Diffusers has a couple of open feature requests for all three components - feel free to gloss over them
297
+ if you don't know yet what specific component you would like to add:
298
+ - [Model or pipeline](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+pipeline%2Fmodel%22)
299
+ - [Scheduler](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+scheduler%22)
300
+
301
+ Before adding any of the three components, it is strongly recommended that you give the [Philosophy guide](https://github.com/huggingface/diffusers/blob/main/PHILOSOPHY.md) a read to better understand the design of any of the three components. Please be aware that
302
+ we cannot merge model, scheduler, or pipeline additions that strongly diverge from our design philosophy
303
+ as it will lead to API inconsistencies. If you fundamentally disagree with a design choice, please
304
+ open a [Feedback issue](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=&template=feedback.md&title=) instead so that it can be discussed whether a certain design
305
+ pattern/design choice shall be changed everywhere in the library and whether we shall update our design philosophy. Consistency across the library is very important for us.
306
+
307
+ Please make sure to add links to the original codebase/paper to the PR and ideally also ping the
308
+ original author directly on the PR so that they can follow the progress and potentially help with questions.
309
+
310
+ If you are unsure or stuck in the PR, don't hesitate to leave a message to ask for a first review or help.
311
+
312
+ ## How to write a good issue
313
+
314
+ **The better your issue is written, the higher the chances that it will be quickly resolved.**
315
+
316
+ 1. Make sure that you've used the correct template for your issue. You can pick between *Bug Report*, *Feature Request*, *Feedback about API Design*, *New model/pipeline/scheduler addition*, *Forum*, or a blank issue. Make sure to pick the correct one when opening [a new issue](https://github.com/huggingface/diffusers/issues/new/choose).
317
+ 2. **Be precise**: Give your issue a fitting title. Try to formulate your issue description as simple as possible. The more precise you are when submitting an issue, the less time it takes to understand the issue and potentially solve it. Make sure to open an issue for one issue only and not for multiple issues. If you found multiple issues, simply open multiple issues. If your issue is a bug, try to be as precise as possible about what bug it is - you should not just write "Error in diffusers".
318
+ 3. **Reproducibility**: No reproducible code snippet == no solution. If you encounter a bug, maintainers **have to be able to reproduce** it. Make sure that you include a code snippet that can be copy-pasted into a Python interpreter to reproduce the issue. Make sure that your code snippet works, *i.e.* that there are no missing imports or missing links to images, ... Your issue should contain an error message **and** a code snippet that can be copy-pasted without any changes to reproduce the exact same error message. If your issue is using local model weights or local data that cannot be accessed by the reader, the issue cannot be solved. If you cannot share your data or model, try to make a dummy model or dummy data.
319
+ 4. **Minimalistic**: Try to help the reader as much as you can to understand the issue as quickly as possible by staying as concise as possible. Remove all code / all information that is irrelevant to the issue. If you have found a bug, try to create the easiest code example you can to demonstrate your issue, do not just dump your whole workflow into the issue as soon as you have found a bug. E.g., if you train a model and get an error at some point during the training, you should first try to understand what part of the training code is responsible for the error and try to reproduce it with a couple of lines. Try to use dummy data instead of full datasets.
320
+ 5. Add links. If you are referring to a certain naming, method, or model make sure to provide a link so that the reader can better understand what you mean. If you are referring to a specific PR or issue, make sure to link it to your issue. Do not assume that the reader knows what you are talking about. The more links you add to your issue the better.
321
+ 6. Formatting. Make sure to nicely format your issue by formatting code into Python code syntax, and error messages into normal code syntax. See the [official GitHub formatting docs](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax) for more information.
322
+ 7. Think of your issue not as a ticket to be solved, but rather as a beautiful entry to a well-written encyclopedia. Every added issue is a contribution to publicly available knowledge. By adding a nicely written issue you not only make it easier for maintainers to solve your issue, but you are helping the whole community to better understand a certain aspect of the library.
323
+
324
+ ## How to write a good PR
325
+
326
+ 1. Be a chameleon. Understand existing design patterns and syntax and make sure your code additions flow seamlessly into the existing code base. Pull requests that significantly diverge from existing design patterns or user interfaces will not be merged.
327
+ 2. Be laser focused. A pull request should solve one problem and one problem only. Make sure to not fall into the trap of "also fixing another problem while we're adding it". It is much more difficult to review pull requests that solve multiple, unrelated problems at once.
328
+ 3. If helpful, try to add a code snippet that displays an example of how your addition can be used.
329
+ 4. The title of your pull request should be a summary of its contribution.
330
+ 5. If your pull request addresses an issue, please mention the issue number in
331
+ the pull request description to make sure they are linked (and people
332
+ consulting the issue know you are working on it);
333
+ 6. To indicate a work in progress please prefix the title with `[WIP]`. These
334
+ are useful to avoid duplicated work, and to differentiate it from PRs ready
335
+ to be merged;
336
+ 7. Try to formulate and format your text as explained in [How to write a good issue](#how-to-write-a-good-issue).
337
+ 8. Make sure existing tests pass;
338
+ 9. Add high-coverage tests. No quality testing = no merge.
339
+ - If you are adding new `@slow` tests, make sure they pass using
340
+ `RUN_SLOW=1 python -m pytest tests/test_my_new_model.py`.
341
+ CircleCI does not run the slow tests, but GitHub Actions does every night!
342
+ 10. All public methods must have informative docstrings that work nicely with markdown. See [`pipeline_latent_diffusion.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/pipelines/latent_diffusion/pipeline_latent_diffusion.py) for an example.
343
+ 11. Due to the rapidly growing repository, it is important to make sure that no files that would significantly weigh down the repository are added. This includes images, videos, and other non-text files. We prefer to leverage a hf.co hosted `dataset` like
344
+ [`hf-internal-testing`](https://huggingface.co/hf-internal-testing) or [huggingface/documentation-images](https://huggingface.co/datasets/huggingface/documentation-images) to place these files.
345
+ If an external contribution, feel free to add the images to your PR and ask a Hugging Face member to migrate your images
346
+ to this dataset.
347
+
348
+ ## How to open a PR
349
+
350
+ Before writing code, we strongly advise you to search through the existing PRs or
351
+ issues to make sure that nobody is already working on the same thing. If you are
352
+ unsure, it is always a good idea to open an issue to get some feedback.
353
+
354
+ You will need basic `git` proficiency to be able to contribute to
355
+ 🧨 Diffusers. `git` is not the easiest tool to use but it has the greatest
356
+ manual. Type `git --help` in a shell and enjoy. If you prefer books, [Pro
357
+ Git](https://git-scm.com/book/en/v2) is a very good reference.
358
+
359
+ Follow these steps to start contributing ([supported Python versions](https://github.com/huggingface/diffusers/blob/42f25d601a910dceadaee6c44345896b4cfa9928/setup.py#L270)):
360
+
361
+ 1. Fork the [repository](https://github.com/huggingface/diffusers) by
362
+ clicking on the 'Fork' button on the repository's page. This creates a copy of the code
363
+ under your GitHub user account.
364
+
365
+ 2. Clone your fork to your local disk, and add the base repository as a remote:
366
+
367
+ ```bash
368
+ $ git clone git@github.com:<your GitHub handle>/diffusers.git
369
+ $ cd diffusers
370
+ $ git remote add upstream https://github.com/huggingface/diffusers.git
371
+ ```
372
+
373
+ 3. Create a new branch to hold your development changes:
374
+
375
+ ```bash
376
+ $ git checkout -b a-descriptive-name-for-my-changes
377
+ ```
378
+
379
+ **Do not** work on the `main` branch.
380
+
381
+ 4. Set up a development environment by running the following command in a virtual environment:
382
+
383
+ ```bash
384
+ $ pip install -e ".[dev]"
385
+ ```
386
+
387
+ If you have already cloned the repo, you might need to `git pull` to get the most recent changes in the
388
+ library.
389
+
390
+ 5. Develop the features on your branch.
391
+
392
+ As you work on the features, you should make sure that the test suite
393
+ passes. You should run the tests impacted by your changes like this:
394
+
395
+ ```bash
396
+ $ pytest tests/<TEST_TO_RUN>.py
397
+ ```
398
+
399
+ Before you run the tests, please make sure you install the dependencies required for testing. You can do so
400
+ with this command:
401
+
402
+ ```bash
403
+ $ pip install -e ".[test]"
404
+ ```
405
+
406
+ You can also run the full test suite with the following command, but it takes
407
+ a beefy machine to produce a result in a decent amount of time now that
408
+ Diffusers has grown a lot. Here is the command for it:
409
+
410
+ ```bash
411
+ $ make test
412
+ ```
413
+
414
+ 🧨 Diffusers relies on `ruff` and `isort` to format its source code
415
+ consistently. After you make changes, apply automatic style corrections and code verifications
416
+ that can't be automated in one go with:
417
+
418
+ ```bash
419
+ $ make style
420
+ ```
421
+
422
+ 🧨 Diffusers also uses `ruff` and a few custom scripts to check for coding mistakes. Quality
423
+ control runs in CI, however, you can also run the same checks with:
424
+
425
+ ```bash
426
+ $ make quality
427
+ ```
428
+
429
+ Once you're happy with your changes, add changed files using `git add` and
430
+ make a commit with `git commit` to record your changes locally:
431
+
432
+ ```bash
433
+ $ git add modified_file.py
434
+ $ git commit -m "A descriptive message about your changes."
435
+ ```
436
+
437
+ It is a good idea to sync your copy of the code with the original
438
+ repository regularly. This way you can quickly account for changes:
439
+
440
+ ```bash
441
+ $ git pull upstream main
442
+ ```
443
+
444
+ Push the changes to your account using:
445
+
446
+ ```bash
447
+ $ git push -u origin a-descriptive-name-for-my-changes
448
+ ```
449
+
450
+ 6. Once you are satisfied, go to the
451
+ webpage of your fork on GitHub. Click on 'Pull request' to send your changes
452
+ to the project maintainers for review.
453
+
454
+ 7. It's ok if maintainers ask you for changes. It happens to core contributors
455
+ too! So everyone can see the changes in the Pull request, work in your local
456
+ branch and push the changes to your fork. They will automatically appear in
457
+ the pull request.
458
+
459
+ ### Tests
460
+
461
+ An extensive test suite is included to test the library behavior and several examples. Library tests can be found in
462
+ the [tests folder](https://github.com/huggingface/diffusers/tree/main/tests).
463
+
464
+ We like `pytest` and `pytest-xdist` because it's faster. From the root of the
465
+ repository, here's how to run tests with `pytest` for the library:
466
+
467
+ ```bash
468
+ $ python -m pytest -n auto --dist=loadfile -s -v ./tests/
469
+ ```
470
+
471
+ In fact, that's how `make test` is implemented!
472
+
473
+ You can specify a smaller set of tests in order to test only the feature
474
+ you're working on.
475
+
476
+ By default, slow tests are skipped. Set the `RUN_SLOW` environment variable to
477
+ `yes` to run them. This will download many gigabytes of models — make sure you
478
+ have enough disk space and a good Internet connection, or a lot of patience!
479
+
480
+ ```bash
481
+ $ RUN_SLOW=yes python -m pytest -n auto --dist=loadfile -s -v ./tests/
482
+ ```
483
+
484
+ `unittest` is fully supported, here's how to run tests with it:
485
+
486
+ ```bash
487
+ $ python -m unittest discover -s tests -t . -v
488
+ $ python -m unittest discover -s examples -t examples -v
489
+ ```
490
+
491
+ ### Syncing forked main with upstream (HuggingFace) main
492
+
493
+ To avoid pinging the upstream repository which adds reference notes to each upstream PR and sends unnecessary notifications to the developers involved in these PRs,
494
+ when syncing the main branch of a forked repository, please, follow these steps:
495
+ 1. When possible, avoid syncing with the upstream using a branch and PR on the forked repository. Instead, merge directly into the forked main.
496
+ 2. If a PR is absolutely necessary, use the following steps after checking out your branch:
497
+ ```bash
498
+ $ git checkout -b your-branch-for-syncing
499
+ $ git pull --squash --no-commit upstream main
500
+ $ git commit -m '<your message without GitHub references>'
501
+ $ git push --set-upstream origin your-branch-for-syncing
502
+ ```
503
+
504
+ ### Style guide
505
+
506
+ For documentation strings, 🧨 Diffusers follows the [Google style](https://google.github.io/styleguide/pyguide.html).

79
+ by such Contributor that are necessarily infringed by their
80
+ Contribution(s) alone or by combination of their Contribution(s)
81
+ with the Work to which such Contribution(s) was submitted. If You
82
+ institute patent litigation against any entity (including a
83
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
84
+ or a Contribution incorporated within the Work constitutes direct
85
+ or contributory patent infringement, then any patent licenses
86
+ granted to You under this License for that Work shall terminate
87
+ as of the date such litigation is filed.
88
+
89
+ 4. Redistribution. You may reproduce and distribute copies of the
90
+ Work or Derivative Works thereof in any medium, with or without
91
+ modifications, and in Source or Object form, provided that You
92
+ meet the following conditions:
93
+
94
+ (a) You must give any other recipients of the Work or

+ Derivative Works a copy of this License; and
96
+
97
+ (b) You must cause any modified files to carry prominent notices
98
+ stating that You changed the files; and
99
+
100
+ (c) You must retain, in the Source form of any Derivative Works
101
+ that You distribute, all copyright, patent, trademark, and
102
+ attribution notices from the Source form of the Work,
103
+ excluding those notices that do not pertain to any part of
104
+ the Derivative Works; and
105
+
106
+ (d) If the Work includes a "NOTICE" text file as part of its
107
+ distribution, then any Derivative Works that You distribute must
108
+ include a readable copy of the attribution notices contained
109
+ within such NOTICE file, excluding those notices that do not
110
+ pertain to any part of the Derivative Works, in at least one
111
+ of the following places: within a NOTICE text file distributed
112
+ as part of the Derivative Works; within the Source form or
113
+ documentation, if provided along with the Derivative Works; or,
114
+ within a display generated by the Derivative Works, if and
115
+ wherever such third-party notices normally appear. The contents
116
+ of the NOTICE file are for informational purposes only and
117
+ do not modify the License. You may add Your own attribution
118
+ notices within Derivative Works that You distribute, alongside
119
+ or as an addendum to the NOTICE text from the Work, provided
120
+ that such additional attribution notices cannot be construed
121
+ as modifying the License.
122
+
123
+ You may add Your own copyright statement to Your modifications and
124
+ may provide additional or different license terms and conditions
125
+ for use, reproduction, or distribution of Your modifications, or
126
+ for any such Derivative Works as a whole, provided Your use,
127
+ reproduction, and distribution of the Work otherwise complies with
128
+ the conditions stated in this License.
129
+
130
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
131
+ any Contribution intentionally submitted for inclusion in the Work
132
+ by You to the Licensor shall be under the terms and conditions of
133
+ this License, without any additional terms or conditions.
134
+ Notwithstanding the above, nothing herein shall supersede or modify
135
+ the terms of any separate license agreement you may have executed
136
+ with Licensor regarding such Contributions.
137
+
138
+ 6. Trademarks. This License does not grant permission to use the trade
139
+ names, trademarks, service marks, or product names of the Licensor,
140
+ except as required for reasonable and customary use in describing the
141
+ origin of the Work and reproducing the content of the NOTICE file.
142
+
143
+ 7. Disclaimer of Warranty. Unless required by applicable law or
144
+ agreed to in writing, Licensor provides the Work (and each
145
+ Contributor provides its Contributions) on an "AS IS" BASIS,
146
+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147
+ implied, including, without limitation, any warranties or conditions
148
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149
+ PARTICULAR PURPOSE. You are solely responsible for determining the
150
+ appropriateness of using or redistributing the Work and assume any
151
+ risks associated with Your exercise of permissions under this License.
152
+
153
+ 8. Limitation of Liability. In no event and under no legal theory,
154
+ whether in tort (including negligence), contract, or otherwise,
155
+ unless required by applicable law (such as deliberate and grossly
156
+ negligent acts) or agreed to in writing, shall any Contributor be
157
+ liable to You for damages, including any direct, indirect, special,
158
+ incidental, or consequential damages of any character arising as a
159
+ result of this License or out of the use or inability to use the
160
+ Work (including but not limited to damages for loss of goodwill,
161
+ work stoppage, computer failure or malfunction, or any and all
162
+ other commercial damages or losses), even if such Contributor
163
+ has been advised of the possibility of such damages.
164
+
165
+ 9. Accepting Warranty or Additional Liability. While redistributing
166
+ the Work or Derivative Works thereof, You may choose to offer,
167
+ and charge a fee for, acceptance of support, warranty, indemnity,
168
+ or other liability obligations and/or rights consistent with this
169
+ License. However, in accepting such obligations, You may act only
170
+ on Your own behalf and on Your sole responsibility, not on behalf
171
+ of any other Contributor, and only if You agree to indemnify,
172
+ defend, and hold each Contributor harmless for any liability
173
+ incurred by, or claims asserted against, such Contributor by reason
174
+ of your accepting any such warranty or additional liability.
175
+
176
+ END OF TERMS AND CONDITIONS
177
+
178
+ APPENDIX: How to apply the Apache License to your work.
179
+
180
+ To apply the Apache License to your work, attach the following

+ # Philosophy
14
+
15
+ 🧨 Diffusers provides **state-of-the-art** pretrained diffusion models across multiple modalities.
16
+ Its purpose is to serve as a **modular toolbox** for both inference and training.
17
+
18
+ We aim to build a library that stands the test of time and therefore take API design very seriously.
19
+
20
+ In a nutshell, Diffusers is built to be a natural extension of PyTorch. Therefore, most of our design choices are based on [PyTorch's Design Principles](https://pytorch.org/docs/stable/community/design.html#pytorch-design-philosophy). Let's go over the most important ones:
21
+
22
+ ## Usability over Performance
23
+
24
+ - While Diffusers has many built-in performance-enhancing features (see [Memory and Speed](https://huggingface.co/docs/diffusers/optimization/fp16)), models are always loaded with the highest precision and lowest optimization. Therefore, by default diffusion pipelines are always instantiated on CPU with float32 precision if not otherwise defined by the user. This ensures usability across different platforms and accelerators and means that no complex installations are required to run the library.
25
+ - Diffusers aims to be a **light-weight** package and therefore has very few required dependencies, but many soft dependencies that can improve performance (such as `accelerate`, `safetensors`, `onnx`, etc...). We strive to keep the library as lightweight as possible so that it can be added without much concern as a dependency on other packages.
26
+ - Diffusers prefers simple, self-explainable code over condensed, magic code. This means that short-hand code syntaxes such as lambda functions, and advanced PyTorch operators are often not desired.
27
+
28
+ ## Simple over easy
29
+
30
+ As PyTorch states, **explicit is better than implicit** and **simple is better than complex**. This design philosophy is reflected in multiple parts of the library:
31
+ - We follow PyTorch's API with methods like [`DiffusionPipeline.to`](https://huggingface.co/docs/diffusers/main/en/api/diffusion_pipeline#diffusers.DiffusionPipeline.to) to let the user handle device management.
32
+ - Raising concise error messages is preferred to silently correct erroneous input. Diffusers aims at teaching the user, rather than making the library as easy to use as possible.
33
+ - Complex model vs. scheduler logic is exposed instead of magically handled inside. Schedulers/Samplers are separated from diffusion models with minimal dependencies on each other. This forces the user to write the unrolled denoising loop. However, the separation allows for easier debugging and gives the user more control over adapting the denoising process or switching out diffusion models or schedulers.
34
+ - Separately trained components of the diffusion pipeline, *e.g.* the text encoder, the UNet, and the variational autoencoder, each has their own model class. This forces the user to handle the interaction between the different model components, and the serialization format separates the model components into different files. However, this allows for easier debugging and customization. DreamBooth or Textual Inversion training
35
+ is very simple thanks to Diffusers' ability to separate single components of the diffusion pipeline.
36
+
37
+ ## Tweakable, contributor-friendly over abstraction
38
+
39
+ For large parts of the library, Diffusers adopts an important design principle of the [Transformers library](https://github.com/huggingface/transformers), which is to prefer copy-pasted code over hasty abstractions. This design principle is very opinionated and stands in stark contrast to popular design principles such as [Don't repeat yourself (DRY)](https://en.wikipedia.org/wiki/Don%27t_repeat_yourself).
40
+ In short, just like Transformers does for modeling files, Diffusers prefers to keep an extremely low level of abstraction and very self-contained code for pipelines and schedulers.
41
+ Functions, long code blocks, and even classes can be copied across multiple files which at first can look like a bad, sloppy design choice that makes the library unmaintainable.
42
+ **However**, this design has proven to be extremely successful for Transformers and makes a lot of sense for community-driven, open-source machine learning libraries because:
43
+ - Machine Learning is an extremely fast-moving field in which paradigms, model architectures, and algorithms are changing rapidly, which therefore makes it very difficult to define long-lasting code abstractions.
44
+ - Machine Learning practitioners like to be able to quickly tweak existing code for ideation and research and therefore prefer self-contained code over one that contains many abstractions.
45
+ - Open-source libraries rely on community contributions and therefore must build a library that is easy to contribute to. The more abstract the code, the more dependencies, the harder to read, and the harder to contribute to. Contributors simply stop contributing to very abstract libraries out of fear of breaking vital functionality. If contributing to a library cannot break other fundamental code, not only is it more inviting for potential new contributors, but it is also easier to review and contribute to multiple parts in parallel.
46
+
47
+ At Hugging Face, we call this design the **single-file policy** which means that almost all of the code of a certain class should be written in a single, self-contained file. To read more about the philosophy, you can have a look
48
+ at [this blog post](https://huggingface.co/blog/transformers-design-philosophy).
49
+
50
+ In Diffusers, we follow this philosophy for both pipelines and schedulers, but only partly for diffusion models. The reason we don't follow this design fully for diffusion models is because almost all diffusion pipelines, such
51
+ as [DDPM](https://huggingface.co/docs/diffusers/api/pipelines/ddpm), [Stable Diffusion](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/overview#stable-diffusion-pipelines), [unCLIP (DALL·E 2)](https://huggingface.co/docs/diffusers/api/pipelines/unclip) and [Imagen](https://imagen.research.google/) all rely on the same diffusion model, the [UNet](https://huggingface.co/docs/diffusers/api/models/unet2d-cond).
52
+
53
+ Great, now you should have generally understood why 🧨 Diffusers is designed the way it is 🤗.
54
+ We try to apply these design principles consistently across the library. Nevertheless, there are some minor exceptions to the philosophy or some unlucky design choices. If you have feedback regarding the design, we would ❤️ to hear it [directly on GitHub](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=&template=feedback.md&title=).
55
+
56
+ ## Design Philosophy in Details
57
+
58
+ Now, let's look a bit into the nitty-gritty details of the design philosophy. Diffusers essentially consists of three major classes: [pipelines](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines), [models](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models), and [schedulers](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers).
59
+ Let's walk through more detailed design decisions for each class.
60
+
61
+ ### Pipelines
62
+
63
+ Pipelines are designed to be easy to use (therefore do not follow [*Simple over easy*](#simple-over-easy) 100%), are not feature complete, and should loosely be seen as examples of how to use [models](#models) and [schedulers](#schedulers) for inference.
64
+
65
+ The following design principles are followed:
66
+ - Pipelines follow the single-file policy. All pipelines can be found in individual directories under src/diffusers/pipelines. One pipeline folder corresponds to one diffusion paper/project/release. Multiple pipeline files can be gathered in one pipeline folder, as it’s done for [`src/diffusers/pipelines/stable-diffusion`](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines/stable_diffusion). If pipelines share similar functionality, one can make use of the [# Copied from mechanism](https://github.com/huggingface/diffusers/blob/125d783076e5bd9785beb05367a2d2566843a271/src/diffusers/pipelines/stable_diffusion/pipeline_stable_diffusion_img2img.py#L251).
67
+ - Pipelines all inherit from [`DiffusionPipeline`].
68
+ - Every pipeline consists of different model and scheduler components, that are documented in the [`model_index.json` file](https://huggingface.co/runwayml/stable-diffusion-v1-5/blob/main/model_index.json), are accessible under the same name as attributes of the pipeline and can be shared between pipelines with [`DiffusionPipeline.components`](https://huggingface.co/docs/diffusers/main/en/api/diffusion_pipeline#diffusers.DiffusionPipeline.components) function.
69
+ - Every pipeline should be loadable via the [`DiffusionPipeline.from_pretrained`](https://huggingface.co/docs/diffusers/main/en/api/diffusion_pipeline#diffusers.DiffusionPipeline.from_pretrained) function.
70
+ - Pipelines should be used **only** for inference.
71
+ - Pipelines should be very readable, self-explanatory, and easy to tweak.
72
+ - Pipelines should be designed to build on top of each other and be easy to integrate into higher-level APIs.
73
+ - Pipelines are **not** intended to be feature-complete user interfaces. For feature-complete user interfaces one should rather have a look at [InvokeAI](https://github.com/invoke-ai/InvokeAI), [Diffuzers](https://github.com/abhishekkrthakur/diffuzers), and [lama-cleaner](https://github.com/Sanster/lama-cleaner).
74
+ - Every pipeline should have one and only one way to run it via a `__call__` method. The naming of the `__call__` arguments should be shared across all pipelines.
75
+ - Pipelines should be named after the task they are intended to solve.
76
+ - In almost all cases, novel diffusion pipelines shall be implemented in a new pipeline folder/file.
77
+
78
+ ### Models
79
+
80
+ Models are designed as configurable toolboxes that are natural extensions of [PyTorch's Module class](https://pytorch.org/docs/stable/generated/torch.nn.Module.html). They only partly follow the **single-file policy**.
81
+
82
+ The following design principles are followed:
83
+ - Models correspond to **a type of model architecture**. *E.g.* the [`UNet2DConditionModel`] class is used for all UNet variations that expect 2D image inputs and are conditioned on some context.
84
+ - All models can be found in [`src/diffusers/models`](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models) and every model architecture shall be defined in its file, e.g. [`unets/unet_2d_condition.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/unets/unet_2d_condition.py), [`transformers/transformer_2d.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/transformers/transformer_2d.py), etc...
85
+ - Models **do not** follow the single-file policy and should make use of smaller model building blocks, such as [`attention.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention.py), [`resnet.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/resnet.py), [`embeddings.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/embeddings.py), etc... **Note**: This is in stark contrast to Transformers' modeling files and shows that models do not really follow the single-file policy.
86
+ - Models intend to expose complexity, just like PyTorch's `Module` class, and give clear error messages.
87
+ - Models all inherit from `ModelMixin` and `ConfigMixin`.
88
+ - Models can be optimized for performance when it doesn’t demand major code changes, keep backward compatibility, and give significant memory or compute gain.
89
+ - Models should by default have the highest precision and lowest performance setting.
90
+ - To integrate new model checkpoints whose general architecture can be classified as an architecture that already exists in Diffusers, the existing model architecture shall be adapted to make it work with the new checkpoint. One should only create a new file if the model architecture is fundamentally different.
91
+ - Models should be designed to be easily extendable to future changes. This can be achieved by limiting public function arguments, configuration arguments, and "foreseeing" future changes, *e.g.* it is usually better to add `string` "...type" arguments that can easily be extended to new future types instead of boolean `is_..._type` arguments. Only the minimum amount of changes shall be made to existing architectures to make a new model checkpoint work.
92
+ - The model design is a difficult trade-off between keeping code readable and concise and supporting many model checkpoints. For most parts of the modeling code, classes shall be adapted for new model checkpoints, while there are some exceptions where it is preferred to add new classes to make sure the code is kept concise and
93
+ readable long-term, such as [UNet blocks](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/unets/unet_2d_blocks.py) and [Attention processors](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
94
+
95
+ ### Schedulers
96
+
97
+ Schedulers are responsible to guide the denoising process for inference as well as to define a noise schedule for training. They are designed as individual classes with loadable configuration files and strongly follow the **single-file policy**.
98
+
99
+ The following design principles are followed:
100
+ - All schedulers are found in [`src/diffusers/schedulers`](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers).
101
+ - Schedulers are **not** allowed to import from large utils files and shall be kept very self-contained.
102
+ - One scheduler Python file corresponds to one scheduler algorithm (as might be defined in a paper).
103
+ - If schedulers share similar functionalities, we can make use of the `# Copied from` mechanism.
104
+ - Schedulers all inherit from `SchedulerMixin` and `ConfigMixin`.
105
+ - Schedulers can be easily swapped out with the [`ConfigMixin.from_config`](https://huggingface.co/docs/diffusers/main/en/api/configuration#diffusers.ConfigMixin.from_config) method as explained in detail [here](./docs/source/en/using-diffusers/schedulers.md).
106
+ - Every scheduler has to have a `set_num_inference_steps`, and a `step` function. `set_num_inference_steps(...)` has to be called before every denoising process, *i.e.* before `step(...)` is called.
107
+ - Every scheduler exposes the timesteps to be "looped over" via a `timesteps` attribute, which is an array of timesteps the model will be called upon.
108
+ - The `step(...)` function takes a predicted model output and the "current" sample (x_t) and returns the "previous", slightly more denoised sample (x_t-1).
109
+ - Given the complexity of diffusion schedulers, the `step` function does not expose all the complexity and can be a bit of a "black box".
110
+ - In almost all cases, novel schedulers shall be implemented in a new scheduling file.

30
+ 🤗 Diffusers is the go-to library for state-of-the-art pretrained diffusion models for generating images, audio, and even 3D structures of molecules. Whether you're looking for a simple inference solution or training your own diffusion models, 🤗 Diffusers is a modular toolbox that supports both. Our library is designed with a focus on [usability over performance](https://huggingface.co/docs/diffusers/conceptual/philosophy#usability-over-performance), [simple over easy](https://huggingface.co/docs/diffusers/conceptual/philosophy#simple-over-easy), and [customizability over abstractions](https://huggingface.co/docs/diffusers/conceptual/philosophy#tweakable-contributorfriendly-over-abstraction).
31
+
32
+ 🤗 Diffusers offers three core components:
33
+
34
+ - State-of-the-art [diffusion pipelines](https://huggingface.co/docs/diffusers/api/pipelines/overview) that can be run in inference with just a few lines of code.
35
+ - Interchangeable noise [schedulers](https://huggingface.co/docs/diffusers/api/schedulers/overview) for different diffusion speeds and output quality.
36
+ - Pretrained [models](https://huggingface.co/docs/diffusers/api/models/overview) that can be used as building blocks, and combined with schedulers, for creating your own end-to-end diffusion systems.
37
+
38
+ ## Installation
39
+
40
+ We recommend installing 🤗 Diffusers in a virtual environment from PyPI or Conda. For more details about installing [PyTorch](https://pytorch.org/get-started/locally/) and [Flax](https://flax.readthedocs.io/en/latest/#installation), please refer to their official documentation.

67
+
68
+ ## Quickstart
69
+
70
+ Generating outputs is super easy with 🤗 Diffusers. To generate an image from text, use the `from_pretrained` method to load any pretrained diffusion model (browse the [Hub](https://huggingface.co/models?library=diffusers&sort=downloads) for 30,000+ checkpoints):
71
+
72
+ ```python
73
+ from diffusers import DiffusionPipeline
74
+ import torch
75
+
76
+ pipeline = DiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", torch_dtype=torch.float16)
77
+ pipeline.to("cuda")
78
+ pipeline("An image of a squirrel in Picasso style").images[0]
79
+ ```
80
+
81
+ You can also dig into the models and schedulers toolbox to build your own diffusion system:
82
+
83
+ ```python
84
+ from diffusers import DDPMScheduler, UNet2DModel
85
+ from PIL import Image
86
+ import torch
87
+
88
+ scheduler = DDPMScheduler.from_pretrained("google/ddpm-cat-256")
89
+ model = UNet2DModel.from_pretrained("google/ddpm-cat-256").to("cuda")
90
+ scheduler.set_timesteps(50)
91
+
92
+ sample_size = model.config.sample_size
93
+ noise = torch.randn((1, 3, sample_size, sample_size), device="cuda")
94
+ input = noise
95
+
96
+ for t in scheduler.timesteps:
97
+ with torch.no_grad():
98
+ noisy_residual = model(input, t).sample
99
+ prev_noisy_sample = scheduler.step(noisy_residual, t, input).prev_sample
100
+ input = prev_noisy_sample
101
+
102
+ image = (input / 2 + 0.5).clamp(0, 1)
103
+ image = image.cpu().permute(0, 2, 3, 1).numpy()[0]
104
+ image = Image.fromarray((image * 255).round().astype("uint8"))
105
+ image
106
+ ```

+ ## Credits
218
+
219
+ This library concretizes previous work by many different authors and would not have been possible without their great research and implementations. We'd like to thank, in particular, the following implementations which have helped us in our development and without which the API could not have been as polished today:
220
+
221
+ - @CompVis' latent diffusion models library, available [here](https://github.com/CompVis/latent-diffusion)
222
+ - @hojonathanho original DDPM implementation, available [here](https://github.com/hojonathanho/diffusion) as well as the extremely useful translation into PyTorch by @pesser, available [here](https://github.com/pesser/pytorch_diffusion)
223
+ - @ermongroup's DDIM implementation, available [here](https://github.com/ermongroup/ddim)
224
+ - @yang-song's Score-VE and Score-VP implementations, available [here](https://github.com/yang-song/score_sde_pytorch)
225
+
226
+ We also want to thank @heejkoo for the very helpful overview of papers, code and resources on diffusion models, available [here](https://github.com/heejkoo/Awesome-Diffusion-Models) as well as @crowsonkb and @rromb for useful discussions and insights.
