- ## Installation
106
-
107
-
108
- Install the package via pip:
109
- ```bash
110
- # NOTE: 3.10 <= PYTHON_VERSION < 3.14 is supported.
111
- pip install "qai-hub-models[resnet-2plus1d]"
112
- ```
113
-
114
-
115
- ## Configure Qualcomm® AI Hub Workbench to run this model on a cloud-hosted device
116
-
117
- Sign-in to [Qualcomm® AI Hub Workbench](https://workbench.aihub.qualcomm.com/) with your
118
- Qualcomm® ID. Once signed in navigate to `Account -> Settings -> API Token`.
119
-
120
- With this API token, you can configure your client to run models on the cloud
121
- hosted devices.
122
- ```bash
123
- qai-hub configure --api_token API_TOKEN
124
- ```
125
- Navigate to [docs](https://workbench.aihub.qualcomm.com/docs/) for more information.
126

-
129
- ## Demo off target
130
-
131
- The package contains a simple end-to-end demo that downloads pre-trained
132
- weights and runs this model on a sample input.
133
-
134
- ```bash
135
- python -m qai_hub_models.models.resnet_2plus1d.demo
136
- ```
137
-
138
- The above demo runs a reference implementation of pre-processing, model
139
- inference, and post processing.

- **NOTE**: If you want running in a Jupyter Notebook or Google Colab like
142
- environment, please add the following to your cell (instead of the above).
143
- ```
144
- %run -m qai_hub_models.models.resnet_2plus1d.demo
145

148
- ### Run model on a cloud-hosted device
149
-
150
- In addition to the demo, you can also run the model on a cloud-hosted Qualcomm®
151
- device. This script does the following:
152
- * Performance check on-device on a cloud-hosted device
153
- * Downloads compiled assets that can be deployed on-device for Android.
154
- * Accuracy check between PyTorch and on-device outputs.
155
-
156
- ```bash
157
- python -m qai_hub_models.models.resnet_2plus1d.export
158
- ```
159
-
160
-
161
-
162
- ## How does this work?
163
-
164
- This [export script](https://aihub.qualcomm.com/models/resnet_2plus1d/qai_hub_models/models/ResNet-2Plus1D/export.py)
165
- leverages [Qualcomm® AI Hub](https://aihub.qualcomm.com/) to optimize, validate, and deploy this model
166
- on-device. Lets go through each step below in detail:
167
-
168
- Step 1: **Compile model for on-device deployment**
169
-
170
- To compile a PyTorch model for on-device deployment, we first trace the model
171
- in memory using the `jit.trace` and then call the `submit_compile_job` API.
172
-
173
- ```python
174
- import torch
175
-
176
- import qai_hub as hub
177
- from qai_hub_models.models.resnet_2plus1d import Model
178
-
179
- # Load the model
180
- torch_model = Model.from_pretrained()
181
-
182
- # Device
183
- device = hub.Device("Samsung Galaxy S25")
184
-
185
- # Trace model
186
- input_shape = torch_model.get_input_spec()
187
- sample_inputs = torch_model.sample_inputs()
188
-
189
- pt_model = torch.jit.trace(torch_model, [torch.tensor(data[0]) for _, data in sample_inputs.items()])
190
-
191
- # Compile model on a specific device
192
- compile_job = hub.submit_compile_job(
193
- model=pt_model,
194
- device=device,
195
- input_specs=torch_model.get_input_spec(),
196
- )
197
-
198
- # Get target model to run on-device
199
- target_model = compile_job.get_target_model()
200
-
201
- ```
202
-
203
-
204
- Step 2: **Performance profiling on cloud-hosted device**
205
-
206
- After compiling models from step 1. Models can be profiled model on-device using the
207
- `target_model`. Note that this scripts runs the model on a device automatically
208
- provisioned in the cloud. Once the job is submitted, you can navigate to a
209
- provided job URL to view a variety of on-device performance metrics.
210
- ```python
211
- profile_job = hub.submit_profile_job(
212
- model=target_model,
213
- device=device,
214
- )
215
-
216
- ```
217
-
218
- Step 3: **Verify on-device accuracy**
219
-
220
- To verify the accuracy of the model on-device, you can run on-device inference
221
- on sample input data on the same cloud hosted device.
222
- ```python
223
- input_data = torch_model.sample_inputs()
224
- inference_job = hub.submit_inference_job(
225
- model=target_model,
226
- device=device,
227
- inputs=input_data,
228
- )
229
- on_device_output = inference_job.download_output_data()
230
-
231
- ```
232
- With the output of the model, you can compute like PSNR, relative errors or
233
- spot check the output with expected output.
234
-
235
- **Note**: This on-device profiling and inference requires access to Qualcomm®
236
- AI Hub Workbench. [Sign up for access](https://myaccount.qualcomm.com/signup).

- ## Deploying compiled model to Android
242
-
243
-
244
- The models can be deployed using multiple runtimes:
245
- - TensorFlow Lite (`.tflite` export): [This
246
- tutorial](https://www.tensorflow.org/lite/android/quickstart) provides a
247
- guide to deploy the .tflite model in an Android application.
248
-
249
-
250
- - QNN (`.so` export ): This [sample
251
- app](https://docs.qualcomm.com/bundle/publicresource/topics/80-63442-50/sample_app.html)
252
- provides instructions on how to use the `.so` shared library in an Android application.

+ # ResNet-2Plus1D: Optimized for Qualcomm Devices
 
 
14
 
15
  ResNet (2+1)D Convolutions is a network which explicitly factorizes 3D convolution into two separate and successive operations, a 2D spatial convolution and a 1D temporal convolution. It used for video understanding applications.
16
 
17
+ This is based on the implementation of ResNet-2Plus1D found [here](https://github.com/pytorch/vision/blob/main/torchvision/models/video/resnet.py).
18
+ This repository contains pre-exported model files optimized for Qualcomm® devices. You can use the [Qualcomm® AI Hub Models](https://github.com/quic/ai-hub-models/blob/main/qai_hub_models/models/resnet_2plus1d) library to export with custom configurations. More details on model performance across various devices, can be found [here](#performance-summary).
19
