**NOTE**: If you want running in a Jupyter Notebook or Google Colab like
|
| 140 |
-
environment, please add the following to your cell (instead of the above).
|
| 141 |
-
```
|
| 142 |
-
%run -m qai_hub_models.models.pidnet.demo

### Run model on a cloud-hosted device
|
| 147 |
-
|
| 148 |
-
In addition to the demo, you can also run the model on a cloud-hosted Qualcomm®
|
| 149 |
-
device. This script does the following:
|
| 150 |
-
* Performance check on-device on a cloud-hosted device
|
| 151 |
-
* Downloads compiled assets that can be deployed on-device for Android.
|
| 152 |
-
* Accuracy check between PyTorch and on-device outputs.
|
| 153 |
-
|
| 154 |
-
```bash
|
| 155 |
-
python -m qai_hub_models.models.pidnet.export
|
| 156 |
-
```
|
| 157 |
-
|
| 158 |
-
|
| 159 |
-
|
| 160 |
-
## How does this work?
|
| 161 |
-
|
| 162 |
-
This [export script](https://aihub.qualcomm.com/models/pidnet/qai_hub_models/models/PidNet/export.py)
|
| 163 |
-
leverages [Qualcomm® AI Hub](https://aihub.qualcomm.com/) to optimize, validate, and deploy this model
|
| 164 |
-
on-device. Lets go through each step below in detail:
|
| 165 |
-
|
| 166 |
-
Step 1: **Compile model for on-device deployment**
|
| 167 |
-
|
| 168 |
-
To compile a PyTorch model for on-device deployment, we first trace the model
|
| 169 |
-
in memory using the `jit.trace` and then call the `submit_compile_job` API.
|
| 170 |
-
|
| 171 |
-
```python
|
| 172 |
-
import torch
|
| 173 |
-
|
| 174 |
-
import qai_hub as hub
|
| 175 |
-
from qai_hub_models.models.pidnet import Model
|
| 176 |
-
|
| 177 |
-
# Load the model
|
| 178 |
-
torch_model = Model.from_pretrained()
|
| 179 |
-
|
| 180 |
-
# Device
|
| 181 |
-
device = hub.Device("Samsung Galaxy S25")
|
| 182 |
-
|
| 183 |
-
# Trace model
|
| 184 |
-
input_shape = torch_model.get_input_spec()
|
| 185 |
-
sample_inputs = torch_model.sample_inputs()
|
| 186 |
-
|
| 187 |
-
pt_model = torch.jit.trace(torch_model, [torch.tensor(data[0]) for _, data in sample_inputs.items()])
|
| 188 |
-
|
| 189 |
-
# Compile model on a specific device
|
| 190 |
-
compile_job = hub.submit_compile_job(
|
| 191 |
-
model=pt_model,
|
| 192 |
-
device=device,
|
| 193 |
-
input_specs=torch_model.get_input_spec(),
|
| 194 |
-
)
|
| 195 |
-
|
| 196 |
-
# Get target model to run on-device
|
| 197 |
-
target_model = compile_job.get_target_model()
|
| 198 |
-
|
| 199 |
-
```
|
| 200 |
-
|
| 201 |
-
|
| 202 |
-
Step 2: **Performance profiling on cloud-hosted device**
|
| 203 |
-
|
| 204 |
-
After compiling models from step 1. Models can be profiled model on-device using the
|
| 205 |
-
`target_model`. Note that this scripts runs the model on a device automatically
|
| 206 |
-
provisioned in the cloud. Once the job is submitted, you can navigate to a
|
| 207 |
-
provided job URL to view a variety of on-device performance metrics.
|
| 208 |
-
```python
|
| 209 |
-
profile_job = hub.submit_profile_job(
|
| 210 |
-
model=target_model,
|
| 211 |
-
device=device,
|
| 212 |
-
)
|
| 213 |
-
|
| 214 |
-
```
|
| 215 |
-
|
| 216 |
-
Step 3: **Verify on-device accuracy**
|
| 217 |
-
|
| 218 |
-
To verify the accuracy of the model on-device, you can run on-device inference
|
| 219 |
-
on sample input data on the same cloud hosted device.
|
| 220 |
-
```python
|
| 221 |
-
input_data = torch_model.sample_inputs()
|
| 222 |
-
inference_job = hub.submit_inference_job(
|
| 223 |
-
model=target_model,
|
| 224 |
-
device=device,
|
| 225 |
-
inputs=input_data,
|
| 226 |
-
)
|
| 227 |
-
on_device_output = inference_job.download_output_data()
|
| 228 |
-
|
| 229 |
-
```
|
| 230 |
-
With the output of the model, you can compute like PSNR, relative errors or
|
| 231 |
-
spot check the output with expected output.
|
| 232 |
-
|
| 233 |
-
**Note**: This on-device profiling and inference requires access to Qualcomm®
|
| 234 |
-
AI Hub Workbench. [Sign up for access](https://myaccount.qualcomm.com/signup).
|
| 235 |
-
|
| 236 |
-
|
| 237 |
-
|
| 238 |
-
## Run demo on a cloud-hosted device
|
| 239 |
-
|
| 240 |
-
You can also run the demo on-device.
|
| 241 |
-
|
| 242 |
-
```bash
|
| 243 |
-
python -m qai_hub_models.models.pidnet.demo --eval-mode on-device
|
| 244 |
-
```
|
| 245 |
-
|
| 246 |
-
**NOTE**: If you want running in a Jupyter Notebook or Google Colab like
|
| 247 |
-
environment, please add the following to your cell (instead of the above).
|
| 248 |
-
```
|
| 249 |
-
%run -m qai_hub_models.models.pidnet.demo -- --eval-mode on-device
|
| 250 |
-
```
|
| 251 |
-
|
| 252 |
-
|
| 253 |
-
## Deploying compiled model to Android
|
| 254 |
-
|
| 255 |
-
|
| 256 |
-
The models can be deployed using multiple runtimes:
|
| 257 |
-
- TensorFlow Lite (`.tflite` export): [This
|
| 258 |
-
tutorial](https://www.tensorflow.org/lite/android/quickstart) provides a
|
| 259 |
-
guide to deploy the .tflite model in an Android application.
|
| 260 |
-

# PidNet: Optimized for Qualcomm Devices
|
|
|
|
|
|
|
| 14 |
|
| 15 |
PIDNet (Proportional-Integral-Derivative Network) is a real-time semantic segmentation model based on PID controllers
|
| 16 |
|
| 17 |
+
This is based on the implementation of PidNet found [here](https://github.com/XuJiacong/PIDNet).
|
| 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/pidnet) library to export with custom configurations. More details on model performance across various devices, can be found [here](#performance-summary).
|
| 19 |
+
|
| 20 |
+
Qualcomm AI Hub Models uses [Qualcomm AI Hub Workbench](https://workbench.aihub.qualcomm.com) to compile, profile, and evaluate this model. [Sign up](https://myaccount.qualcomm.com/signup) to run these models on a hosted Qualcomm® device.
|
| 21 |
