v4.46.2 is available.
Auto Classes
In many cases, the architecture you want to use can be guessed from the name or the path of the pretrained model you
are supplying to the from_pretrained() method. AutoClasses are here to do this job for you so that you
automatically retrieve the relevant model given the name/path to the pretrained weights/config/vocabulary.
Instantiating one of AutoConfig, AutoModel, and AutoTokenizer will directly create a class of the relevant architecture. For instance
model = AutoModel.from_pretrained("bert-base-cased")will create a model that is an instance of BertModel.
There is one class of AutoModel for each task, and for each backend (PyTorch, TensorFlow, or Flax).
Extending the Auto Classes
Each of the auto classes has a method to be extended with your custom classes. For instance, if you have defined a
custom class of model NewModel, make sure you have a NewModelConfig then you can add those to the auto
classes like this:
from transformers import AutoConfig, AutoModel
AutoConfig.register("new-model", NewModelConfig)
AutoModel.register(NewModelConfig, NewModel)You will then be able to use the auto classes like you would usually do!
If your NewModelConfig is a subclass of ~transformer.PretrainedConfig, make sure its
model_type attribute is set to the same key you use when registering the config (here "new-model").
Likewise, if your NewModel is a subclass of PreTrainedModel, make sure its
config_class attribute is set to the same class you use when registering the model (here
NewModelConfig).
AutoConfig
This is a generic configuration class that will be instantiated as one of the configuration classes of the library when created with the from_pretrained() class method.
This class cannot be instantiated directly using __init__() (throws an error).

Instantiates one of the base model classes of the library from a configuration.
Note: Loading a model from its configuration file does not load the model weights. It only affects the model’s configuration. Use from_pretrained() to load the model weights.
from_pretrained
< source >( *model_args **kwargs )
Parameters
-
pretrained_model_name_or_path (
stroros.PathLike) — Can be either:- A string, the model id of a pretrained model hosted inside a model repo on huggingface.co.
Valid model ids can be located at the root-level, like
bert-base-uncased, or namespaced under a user or organization name, likedbmdz/bert-base-german-cased. - A path to a directory containing model weights saved using
save_pretrained(), e.g.,
./my_model_directory/. - A path or url to a tensorflow index checkpoint file (e.g,
./tf_model/model.ckpt.index). In this case,from_tfshould be set toTrueand a configuration object should be provided asconfigargument. This loading path is slower than converting the TensorFlow checkpoint in a PyTorch model using the provided conversion scripts and loading the PyTorch model afterwards.
- A string, the model id of a pretrained model hosted inside a model repo on huggingface.co.
Valid model ids can be located at the root-level, like
-
model_args (additional positional arguments, optional) —
Will be passed along to the underlying model
__init__()method. -
config (PretrainedConfig, optional) —
Configuration for the model to use instead of an automatically loaded configuration. Configuration can
be automatically loaded when:
- The model is a model provided by the library (loaded with the model id string of a pretrained model).
- The model was saved using save_pretrained() and is reloaded by supplying the save directory.
- The model is loaded by supplying a local directory as
pretrained_model_name_or_pathand a configuration JSON file named config.json is found in the directory.
-
state_dict (Dict[str, torch.Tensor], optional) —
A state dictionary to use instead of a state dictionary loaded from saved weights file.
This option can be used if you want to create a model from a pretrained configuration but load your own weights. In this case though, you should check if using save_pretrained() and from_pretrained() is not a simpler option.
-
cache_dir (
stroros.PathLike, optional) — Path to a directory in which a downloaded pretrained model configuration should be cached if the standard cache should not be used. -
from_tf (
bool, optional, defaults toFalse) — Load the model weights from a TensorFlow checkpoint save file (see docstring ofpretrained_model_name_or_pathargument). -
force_download (
bool, optional, defaults toFalse) — Whether or not to force the (re-)download of the model weights and configuration files, overriding the cached versions if they exist. -
resume_download (
bool, optional, defaults toFalse) — Whether or not to delete incompletely received files. Will attempt to resume the download if such a file exists. -
proxies (
Dict[str, str], optional) — A dictionary of proxy servers to use by protocol or endpoint, e.g.,{'http': 'foo.bar:3128', 'http://hostname': 'foo.bar:4012'}. The proxies are used on each request. -
output_loading_info(
bool, optional, defaults toFalse) — Whether ot not to also return a dictionary containing missing keys, unexpected keys and error messages. -
local_files_only(
bool, optional, defaults toFalse) — Whether or not to only look at local files (e.g., not try downloading the model). -
revision (
str, optional, defaults to"main") — The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a git-based system for storing models and other artifacts on huggingface.co, sorevisioncan be any identifier allowed by git. -
trust_remote_code (
bool, optional, defaults toFalse) — Whether or not to allow for custom models defined on the Hub in their own modeling files. This option should only be set toTruefor repositories you trust and in which you have read the code, as it will execute code present on the Hub on your local machine. -
kwargs (additional keyword arguments, optional) —
Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,
output_attentions=True). Behaves differently depending on whether aconfigis provided or automatically loaded:- If a configuration is provided with
config,**kwargswill be directly passed to the underlying model’s__init__method (we assume all relevant updates to the configuration have already been done) - If a configuration is not provided,
kwargswill be first passed to the configuration class initialization function (from_pretrained()). Each key ofkwargsthat corresponds to a configuration attribute will be used to override said attribute with the suppliedkwargsvalue. Remaining keys that do not correspond to any configuration attribute will be passed to the underlying model’s__init__function.
- If a configuration is provided with
Instantiate one of the base model classes of the library from a pretrained model.
The model class to instantiate is selected based on the model_type property of the config object (either
passed as an argument or loaded from pretrained_model_name_or_path if possible), or when it’s missing, by

from_pretrained
< source >( *model_args **kwargs )
Parameters
-
pretrained_model_name_or_path (
stroros.PathLike) — Can be either:- A string, the model id of a pretrained model hosted inside a model repo on huggingface.co.
Valid model ids can be located at the root-level, like
bert-base-uncased, or namespaced under a user or organization name, likedbmdz/bert-base-german-cased. - A path to a directory containing model weights saved using
save_pretrained(), e.g.,
./my_model_directory/. - A path or url to a tensorflow index checkpoint file (e.g,
./tf_model/model.ckpt.index). In this case,from_tfshould be set toTrueand a configuration object should be provided asconfigargument. This loading path is slower than converting the TensorFlow checkpoint in a PyTorch model using the provided conversion scripts and loading the PyTorch model afterwards.
- A string, the model id of a pretrained model hosted inside a model repo on huggingface.co.
Valid model ids can be located at the root-level, like
-
model_args (additional positional arguments, optional) —
Will be passed along to the underlying model
__init__()method. -
config (PretrainedConfig, optional) —
Configuration for the model to use instead of an automatically loaded configuration. Configuration can
be automatically loaded when:
- The model is a model provided by the library (loaded with the model id string of a pretrained model).
- The model was saved using save_pretrained() and is reloaded by supplying the save directory.
- The model is loaded by supplying a local directory as
pretrained_model_name_or_pathand a configuration JSON file named config.json is found in the directory.
-
state_dict (Dict[str, torch.Tensor], optional) —
A state dictionary to use instead of a state dictionary loaded from saved weights file.
This option can be used if you want to create a model from a pretrained configuration but load your own weights. In this case though, you should check if using save_pretrained() and from_pretrained() is not a simpler option.
-
cache_dir (
stroros.PathLike, optional) — Path to a directory in which a downloaded pretrained model configuration should be cached if the standard cache should not be used. -
from_tf (
bool, optional, defaults toFalse) — Load the model weights from a TensorFlow checkpoint save file (see docstring ofpretrained_model_name_or_pathargument). -
force_download (
bool, optional, defaults toFalse) — Whether or not to force the (re-)download of the model weights and configuration files, overriding the cached versions if they exist. -
resume_download (
bool, optional, defaults toFalse) — Whether or not to delete incompletely received files. Will attempt to resume the download if such a file exists. -
proxies (
Dict[str, str], optional) — A dictionary of proxy servers to use by protocol or endpoint, e.g.,{'http': 'foo.bar:3128', 'http://hostname': 'foo.bar:4012'}. The proxies are used on each request. -
output_loading_info(
bool, optional, defaults toFalse) — Whether ot not to also return a dictionary containing missing keys, unexpected keys and error messages. -
local_files_only(
bool, optional, defaults toFalse) — Whether or not to only look at local files (e.g., not try downloading the model). -
revision (
str, optional, defaults to"main") — The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a git-based system for storing models and other artifacts on huggingface.co, sorevisioncan be any identifier allowed by git. -
trust_remote_code (
bool, optional, defaults toFalse) — Whether or not to allow for custom models defined on the Hub in their own modeling files. This option should only be set toTruefor repositories you trust and in which you have read the code, as it will execute code present on the Hub on your local machine. -
kwargs (additional keyword arguments, optional) —
Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,
output_attentions=True). Behaves differently depending on whether aconfigis provided or automatically loaded:- If a configuration is provided with
config,**kwargswill be directly passed to the underlying model’s__init__method (we assume all relevant updates to the configuration have already been done) - If a configuration is not provided,
kwargswill be first passed to the configuration class initialization function (from_pretrained()). Each key ofkwargsthat corresponds to a configuration attribute will be used to override said attribute with the suppliedkwargsvalue. Remaining keys that do not correspond to any configuration attribute will be passed to the underlying model’s__init__function.
- If a configuration is provided with
Instantiate one of the model classes of the library (with a pretraining head) from a pretrained model.
The model class to instantiate is selected based on the model_type property of the config object (either
passed as an argument or loaded from pretrained_model_name_or_path if possible), or when it’s missing, by

passed as an argument or loaded from pretrained_model_name_or_path if possible), or when it’s missing, by
falling back to using pattern matching on pretrained_model_name_or_path:
- dpt — DPTForDepthEstimation (DPT model)
- glpn — GLPNForDepthEstimation (GLPN model)
The model is set in evaluation mode by default using model.eval() (so for instance, dropout modules are
deactivated). To train the model, you should first set it back in training mode with model.train()
Examples:
>>> from transformers import AutoConfig, AutoModelForDepthEstimation
>>> # Download model and configuration from huggingface.co and cache.
>>> model = AutoModelForDepthEstimation.from_pretrained("bert-base-cased")
>>> # Update configuration during loading
>>> model = AutoModelForDepthEstimation.from_pretrained("bert-base-cased", output_attentions=True)
>>> model.config.output_attentions
True
>>> # Loading from a TF checkpoint file instead of a PyTorch model (slower)
>>> config = AutoConfig.from_pretrained("./tf_model/bert_tf_model_config.json")
>>> model = AutoModelForDepthEstimation.from_pretrained(
... "./tf_model/bert_tf_checkpoint.ckpt.index", from_tf=True, config=config
... )AutoModelForMaskedLM
This is a generic model class that will be instantiated as one of the model classes of the library (with a masked language modeling head) when created with the from_pretrained() class method or the from_config() class method.
This class cannot be instantiated directly using __init__() (throws an error).

./my_model_directory/. - A path or url to a tensorflow index checkpoint file (e.g,
./tf_model/model.ckpt.index). In this case,from_tfshould be set toTrueand a configuration object should be provided asconfigargument. This loading path is slower than converting the TensorFlow checkpoint in a PyTorch model using the provided conversion scripts and loading the PyTorch model afterwards.

revision (
str, optional, defaults to"main") — The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a git-based system for storing models and other artifacts on huggingface.co, sorevisioncan be any identifier allowed by git. -
trust_remote_code (
bool, optional, defaults toFalse) — Whether or not to allow for custom models defined on the Hub in their own modeling files. This option should only be set toTruefor repositories you trust and in which you have read the code, as it will execute code present on the Hub on your local machine. -

Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,
output_attentions=True). Behaves differently depending on whether aconfigis provided or automatically loaded:- If a configuration is provided with
config,**kwargswill be directly passed to the underlying model’s__init__method (we assume all relevant updates to the configuration have already been done) - If a configuration is not provided,
kwargswill be first passed to the configuration class initialization function (from_pretrained()).

bert-base-uncased, or namespaced under a user or organization name, likedbmdz/bert-base-german-cased. - A path to a directory containing model weights saved using
save_pretrained(), e.g.,
./my_model_directory/. - A path or url to a tensorflow index checkpoint file (e.g,
./tf_model/model.ckpt.index). In this case,from_tfshould be set toTrueand a configuration object should be provided asconfigargument. This loading path is slower than converting the TensorFlow checkpoint in a PyTorch model using the provided conversion scripts and loading the PyTorch model afterwards.

-
model_args (additional positional arguments, optional) —

proxies (
Dict[str, str], optional) — A dictionary of proxy servers to use by protocol or endpoint, e.g.,{'http': 'foo.bar:3128', 'http://hostname': 'foo.bar:4012'}. The proxies are used on each request. -
output_loading_info(
bool, optional, defaults toFalse) — Whether ot not to also return a dictionary containing missing keys, unexpected keys and error messages. -
local_files_only(
bool, optional, defaults toFalse) — Whether or not to only look at local files (e.g., not try downloading the model). -
revision (
str, optional, defaults to"main") — The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a git-based system for storing models and other artifacts on huggingface.co, sorevisioncan be any identifier allowed by git. -
trust_remote_code (
bool, optional, defaults toFalse) — Whether or not to allow for custom models defined on the Hub in their own modeling files. This option should only be set toTruefor repositories you trust and in which you have read the code, as it will execute code present on the Hub on your local machine. -
kwargs (additional keyword arguments, optional) —
Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,

Instantiate one of the model classes of the library (with a document question answering head) from a pretrained model.
The model class to instantiate is selected based on the model_type property of the config object (either
passed as an argument or loaded from pretrained_model_name_or_path if possible), or when it’s missing, by
falling back to using pattern matching on pretrained_model_name_or_path:
- layoutlm — LayoutLMForQuestionAnswering (LayoutLM model)

The model is set in evaluation mode by default using model.eval() (so for instance, dropout modules are
deactivated). To train the model, you should first set it back in training mode with model.train()
Examples:

stroros.PathLike) — Can be either:- A string, the model id of a pretrained model hosted inside a model repo on huggingface.co.
Valid model ids can be located at the root-level, like
bert-base-uncased, or namespaced under a user or organization name, likedbmdz/bert-base-german-cased. - A path to a directory containing model weights saved using
save_pretrained(), e.g.,
./my_model_directory/. - A path or url to a tensorflow index checkpoint file (e.g,
./tf_model/model.ckpt.index). In this case,from_tfshould be set toTrueand a configuration object should be provided asconfigargument. This loading path is slower than converting the TensorFlow checkpoint in a PyTorch model using the provided conversion scripts and loading the PyTorch model afterwards.
- A string, the model id of a pretrained model hosted inside a model repo on huggingface.co.
Valid model ids can be located at the root-level, like
-
model_args (additional positional arguments, optional) —
Will be passed along to the underlying model
__init__()method. -
config (PretrainedConfig, optional) —

- The model was saved using save_pretrained() and is reloaded by supplying the save directory.
- The model is loaded by supplying a local directory as
pretrained_model_name_or_pathand a configuration JSON file named config.json is found in the directory.
-
state_dict (Dict[str, torch.Tensor], optional) —
A state dictionary to use instead of a state dictionary loaded from saved weights file.
This option can be used if you want to create a model from a pretrained configuration but load your own weights. In this case though, you should check if using save_pretrained() and from_pretrained() is not a simpler option.
-
cache_dir (
stroros.PathLike, optional) — Path to a directory in which a downloaded pretrained model configuration should be cached if the standard cache should not be used. -
from_tf (
bool, optional, defaults toFalse) — Load the model weights from a TensorFlow checkpoint save file (see docstring ofpretrained_model_name_or_pathargument). -
force_download (
bool, optional, defaults toFalse) — Whether or not to force the (re-)download of the model weights and configuration files, overriding the cached versions if they exist. -
resume_download (
bool, optional, defaults toFalse) — Whether or not to delete incompletely received files. Will attempt to resume the download if such a file exists. -
proxies (
Dict[str, str], optional) — A dictionary of proxy servers to use by protocol or endpoint, e.g.,{'http': 'foo.bar:3128', 'http://hostname': 'foo.bar:4012'}. The proxies are used on each request. -
output_loading_info(
bool, optional, defaults toFalse) — Whether ot not to also return a dictionary containing missing keys, unexpected keys and error messages. -
local_files_only(
bool, optional, defaults toFalse) — Whether or not to only look at local files (e.g., not try downloading the model). -
revision (
str, optional, defaults to"main") — The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a git-based system for storing models and other artifacts on huggingface.co, sorevisioncan be any identifier allowed by git. -
trust_remote_code (
bool, optional, defaults toFalse) — Whether or not to allow for custom models defined on the Hub in their own modeling files. This option should only be set toTruefor repositories you trust and in which you have read the code, as it will execute code present on the Hub on your local machine. -
kwargs (additional keyword arguments, optional) —
Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,
output_attentions=True). Behaves differently depending on whether aconfigis provided or automatically loaded:- If a configuration is provided with
config,**kwargswill be directly passed to the underlying model’s__init__method (we assume all relevant updates to the configuration have already been done) - If a configuration is not provided,
kwargswill be first passed to the configuration class initialization function (from_pretrained()). Each key ofkwargsthat corresponds to a configuration attribute will be used to override said attribute with the suppliedkwargsvalue. Remaining keys that do not correspond to any configuration attribute will be passed to the underlying model’s__init__function.
- If a configuration is provided with
Instantiate one of the model classes of the library (with a audio classification head) from a pretrained model.
The model class to instantiate is selected based on the model_type property of the config object (either
passed as an argument or loaded from pretrained_model_name_or_path if possible), or when it’s missing, by
falling back to using pattern matching on pretrained_model_name_or_path:

Valid model ids can be located at the root-level, like
-
model_args (additional positional arguments, optional) —
Will be passed along to the underlying model

Configuration for the model to use instead of an automatically loaded configuration. Configuration can
be automatically loaded when:
- The model is a model provided by the library (loaded with the model id string of a pretrained model).
- The model was saved using save_pretrained() and is reloaded by supplying the save directory.
- The model is loaded by supplying a local directory as
pretrained_model_name_or_pathand a configuration JSON file named config.json is found in the directory.
-
state_dict (Dict[str, torch.Tensor], optional) —
A state dictionary to use instead of a state dictionary loaded from saved weights file.
This option can be used if you want to create a model from a pretrained configuration but load your own weights. In this case though, you should check if using save_pretrained() and from_pretrained() is not a simpler option.
-
cache_dir (
stroros.PathLike, optional) — Path to a directory in which a downloaded pretrained model configuration should be cached if the standard cache should not be used. -
from_tf (
bool, optional, defaults toFalse) — Load the model weights from a TensorFlow checkpoint save file (see docstring ofpretrained_model_name_or_pathargument). -
force_download (
bool, optional, defaults toFalse) — Whether or not to force the (re-)download of the model weights and configuration files, overriding the cached versions if they exist. -
resume_download (
bool, optional, defaults toFalse) — Whether or not to delete incompletely received files. Will attempt to resume the download if such a file exists. -
proxies (
Dict[str, str], optional) — A dictionary of proxy servers to use by protocol or endpoint, e.g.,{'http': 'foo.bar:3128', 'http://hostname': 'foo.bar:4012'}. The proxies are used on each request. -
output_loading_info(
bool, optional, defaults toFalse) — Whether ot not to also return a dictionary containing missing keys, unexpected keys and error messages. -
local_files_only(
bool, optional, defaults toFalse) — Whether or not to only look at local files (e.g., not try downloading the model). -
revision (
str, optional, defaults to"main") — The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a git-based system for storing models and other artifacts on huggingface.co, sorevisioncan be any identifier allowed by git. -
trust_remote_code (
bool, optional, defaults toFalse) — Whether or not to allow for custom models defined on the Hub in their own modeling files. This option should only be set toTruefor repositories you trust and in which you have read the code, as it will execute code present on the Hub on your local machine. -
kwargs (additional keyword arguments, optional) —
Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,
output_attentions=True). Behaves differently depending on whether aconfigis provided or automatically loaded:- If a configuration is provided with
config,**kwargswill be directly passed to the underlying model’s__init__method (we assume all relevant updates to the configuration have already been done) - If a configuration is not provided,
kwargswill be first passed to the configuration class initialization function (from_pretrained()). Each key ofkwargsthat corresponds to a configuration attribute will be used to override said attribute with the suppliedkwargsvalue. Remaining keys that do not correspond to any configuration attribute will be passed to the underlying model’s__init__function.
- If a configuration is provided with
Instantiate one of the model classes of the library (with a audio retrieval via x-vector head) from a pretrained model.
The model class to instantiate is selected based on the model_type property of the config object (either
passed as an argument or loaded from pretrained_model_name_or_path if possible), or when it’s missing, by
falling back to using pattern matching on pretrained_model_name_or_path:

- wavlm — WavLMForXVector (WavLM model)
The model is set in evaluation mode by default using model.eval() (so for instance, dropout modules are
deactivated). To train the model, you should first set it back in training mode with model.train()

config,**kwargswill be directly passed to the underlying model’s__init__method (we assume all relevant updates to the configuration have already been done) - If a configuration is not provided,
kwargswill be first passed to the configuration class initialization function (from_pretrained()).

Remaining keys that do not correspond to any configuration attribute will be passed to the underlying model’s__init__function.
- If a configuration is provided with
Instantiate one of the model classes of the library (with a semantic segmentation head) from a pretrained model.
The model class to instantiate is selected based on the model_type property of the config object (either
passed as an argument or loaded from pretrained_model_name_or_path if possible), or when it’s missing, by
falling back to using pattern matching on pretrained_model_name_or_path:
- beit — BeitForSemanticSegmentation (BEiT model)
- data2vec-vision — Data2VecVisionForSemanticSegmentation (Data2VecVision model)
- dpt — DPTForSemanticSegmentation (DPT model)
- mobilevit — MobileViTForSemanticSegmentation (MobileViT model)
- segformer — SegformerForSemanticSegmentation (SegFormer model)
The model is set in evaluation mode by default using model.eval() (so for instance, dropout modules are
deactivated). To train the model, you should first set it back in training mode with model.train()
Examples:
>>> from transformers import AutoConfig, AutoModelForSemanticSegmentation
>>> # Download model and configuration from huggingface.co and cache.
>>> model = AutoModelForSemanticSegmentation.from_pretrained("bert-base-cased")
>>> # Update configuration during loading
>>> model = AutoModelForSemanticSegmentation.from_pretrained("bert-base-cased", output_attentions=True)
>>> model.config.output_attentions
True
>>> # Loading from a TF checkpoint file instead of a PyTorch model (slower)
>>> config = AutoConfig.from_pretrained("./tf_model/bert_tf_model_config.json")
>>> model = AutoModelForSemanticSegmentation.from_pretrained(

revision (
str, optional, defaults to"main") — The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a git-based system for storing models and other artifacts on huggingface.co, sorevisioncan be any identifier allowed by git. -
trust_remote_code (
bool, optional, defaults toFalse) — Whether or not to allow for custom models defined on the Hub in their own modeling files. This option should only be set toTruefor repositories you trust and in which you have read the code, as it will execute code present on the Hub on your local machine. -
kwargs (additional keyword arguments, optional) —
Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,
output_attentions=True). Behaves differently depending on whether aconfigis provided or automatically loaded:- If a configuration is provided with
config,**kwargswill be directly passed to the underlying model’s__init__method (we assume all relevant updates to the configuration have already been done) - If a configuration is not provided,

output_attentions=True). Behaves differently depending on whether aconfigis provided or automatically loaded:- If a configuration is provided with
config,**kwargswill be directly passed to the underlying model’s__init__method (we assume all relevant updates to the configuration have already been done) - If a configuration is not provided,
kwargswill be first passed to the configuration class initialization function (from_pretrained()).

save_pretrained(), e.g.,
./my_model_directory/. - A path or url to a PyTorch state_dict save file (e.g,
./pt_model/pytorch_model.bin). In this case,from_ptshould be set toTrueand a configuration object should be provided asconfigargument. This loading path is slower than converting the PyTorch model in a TensorFlow model using the provided conversion scripts and loading the TensorFlow model afterwards.

falling back to using pattern matching on pretrained_model_name_or_path:
- bert — FlaxBertForNextSentencePrediction (BERT model)
Examples:
>>> from transformers import AutoConfig, FlaxAutoModelForNextSentencePrediction
>>> # Download model and configuration from huggingface.co and cache.
>>> model = FlaxAutoModelForNextSentencePrediction.from_pretrained("bert-base-cased")
>>> # Update configuration during loading
>>> model = FlaxAutoModelForNextSentencePrediction.from_pretrained("bert-base-cased", output_attentions=True)
>>> model.config.output_attentions
True
>>> # Loading from a PyTorch checkpoint file instead of a TensorFlow model (slower)
>>> config = AutoConfig.from_pretrained("./pt_model/bert_pt_model_config.json")
>>> model = FlaxAutoModelForNextSentencePrediction.from_pretrained(
... "./pt_model/bert_pytorch_model.bin", from_pt=True, config=config
... )FlaxAutoModelForImageClassification
This is a generic model class that will be instantiated as one of the model classes of the library (with a image classification head) when created with the from_pretrained() class method or the from_config() class method.
This class cannot be instantiated directly using __init__() (throws an error).
from_config
< source >( **kwargs )
Parameters
-
config (PretrainedConfig) —
The model class to instantiate is selected based on the configuration class:
- BeitConfig configuration class: FlaxBeitForImageClassification (BEiT model)
- ViTConfig configuration class: FlaxViTForImageClassification (ViT model)
Instantiates one of the model classes of the library (with a image classification head) from a configuration.
Note: Loading a model from its configuration file does not load the model weights. It only affects the model’s configuration. Use from_pretrained() to load the model weights.
from_pretrained
< source >( *model_args **kwargs )
Parameters
-
pretrained_model_name_or_path (
stroros.PathLike) — Can be either:- A string, the model id of a pretrained model hosted inside a model repo on huggingface.co.
Valid model ids can be located at the root-level, like
bert-base-uncased, or namespaced under a user or organization name, likedbmdz/bert-base-german-cased. - A path to a directory containing model weights saved using
save_pretrained(), e.g.,
./my_model_directory/. - A path or url to a PyTorch state_dict save file (e.g,
./pt_model/pytorch_model.bin). In this case,from_ptshould be set toTrueand a configuration object should be provided asconfigargument. This loading path is slower than converting the PyTorch model in a TensorFlow model using the provided conversion scripts and loading the TensorFlow model afterwards.
- A string, the model id of a pretrained model hosted inside a model repo on huggingface.co.
Valid model ids can be located at the root-level, like
-
model_args (additional positional arguments, optional) —
Will be passed along to the underlying model
__init__()method. -
config (PretrainedConfig, optional) —
Configuration for the model to use instead of an automatically loaded configuration. Configuration can
be automatically loaded when:
- The model is a model provided by the library (loaded with the model id string of a pretrained model).
- The model was saved using save_pretrained() and is reloaded by supplying the save directory.
- The model is loaded by supplying a local directory as
pretrained_model_name_or_pathand a configuration JSON file named config.json is found in the directory.
-
cache_dir (
stroros.PathLike, optional) — Path to a directory in which a downloaded pretrained model configuration should be cached if the standard cache should not be used. -
from_pt (
bool, optional, defaults toFalse) — Load the model weights from a PyTorch checkpoint save file (see docstring ofpretrained_model_name_or_pathargument). -
force_download (
bool, optional, defaults toFalse) — Whether or not to force the (re-)download of the model weights and configuration files, overriding the cached versions if they exist. -
resume_download (
bool, optional, defaults toFalse) — Whether or not to delete incompletely received files. Will attempt to resume the download if such a file exists. -
proxies (
Dict[str, str], optional) — A dictionary of proxy servers to use by protocol or endpoint, e.g.,{'http': 'foo.bar:3128', 'http://hostname': 'foo.bar:4012'}. The proxies are used on each request. -
output_loading_info(
bool, optional, defaults toFalse) — Whether ot not to also return a dictionary containing missing keys, unexpected keys and error messages. -
local_files_only(
bool, optional, defaults toFalse) — Whether or not to only look at local files (e.g., not try downloading the model). -
revision (
str, optional, defaults to"main") — The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a git-based system for storing models and other artifacts on huggingface.co, sorevisioncan be any identifier allowed by git. -
trust_remote_code (
bool, optional, defaults toFalse) — Whether or not to allow for custom models defined on the Hub in their own modeling files. This option should only be set toTruefor repositories you trust and in which you have read the code, as it will execute code present on the Hub on your local machine. -
kwargs (additional keyword arguments, optional) —
Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,
output_attentions=True). Behaves differently depending on whether aconfigis provided or automatically loaded:- If a configuration is provided with
config,**kwargswill be directly passed to the underlying model’s__init__method (we assume all relevant updates to the configuration have already been done) - If a configuration is not provided,
kwargswill be first passed to the configuration class initialization function (from_pretrained()). Each key ofkwargsthat corresponds to a configuration attribute will be used to override said attribute with the suppliedkwargsvalue. Remaining keys that do not correspond to any configuration attribute will be passed to the underlying model’s__init__function.
