Installation

Install the package via pip:

pip install "qai-hub-models[deepbox]"

Configure Qualcomm® AI Hub to run this model on a cloud-hosted device

Sign-in to Qualcomm® AI Hub with your Qualcomm® ID. Once signed in navigate to Account -> Settings -> API Token.

With this API token, you can configure your client to run models on the cloud hosted devices.

qai-hub configure --api_token API_TOKEN

Navigate to docs for more information.

Demo off target

The package contains a simple end-to-end demo that downloads pre-trained weights and runs this model on a sample input.

python -m qai_hub_models.models.deepbox.demo

The above demo runs a reference implementation of pre-processing, model inference, and post processing.

NOTE: If you want running in a Jupyter Notebook or Google Colab like environment, please add the following to your cell (instead of the above).

%run -m qai_hub_models.models.deepbox.demo

Run model on a cloud-hosted device

In addition to the demo, you can also run the model on a cloud-hosted Qualcomm® device. This script does the following:

  • Performance check on-device on a cloud-hosted device
  • Downloads compiled assets that can be deployed on-device for Android.
  • Accuracy check between PyTorch and on-device outputs.
python -m qai_hub_models.models.deepbox.export

How does this work?

This export script leverages Qualcomm® AI Hub to optimize, validate, and deploy this model on-device. Lets go through each step below in detail:

Step 1: Compile model for on-device deployment

To compile a PyTorch model for on-device deployment, we first trace the model in memory using the jit.trace and then call the submit_compile_job API.

import torch

import qai_hub as hub
from qai_hub_models.models.deepbox import Model

# Load the model
model = Model.from_pretrained()
bbox2D_dectector_model = model.bbox2D_dectector
bbox3D_dectector_model = model.bbox3D_dectector

# Device
device = hub.Device("Samsung Galaxy S23")

# Trace model
bbox2D_dectector_input_shape = bbox2D_dectector_model.get_input_spec()
bbox2D_dectector_sample_inputs = bbox2D_dectector_model.sample_inputs()

traced_bbox2D_dectector_model = torch.jit.trace(bbox2D_dectector_model, [torch.tensor(data[0]) for _, data in bbox2D_dectector_sample_inputs.items()])

# Compile model on a specific device
bbox2D_dectector_compile_job = hub.submit_compile_job(
    model=traced_bbox2D_dectector_model ,
    device=device,
    input_specs=bbox2D_dectector_model.get_input_spec(),
)

# Get target model to run on-device
bbox2D_dectector_target_model = bbox2D_dectector_compile_job.get_target_model()
# Trace model
bbox3D_dectector_input_shape = bbox3D_dectector_model.get_input_spec()
bbox3D_dectector_sample_inputs = bbox3D_dectector_model.sample_inputs()

traced_bbox3D_dectector_model = torch.jit.trace(bbox3D_dectector_model, [torch.tensor(data[0]) for _, data in bbox3D_dectector_sample_inputs.items()])

# Compile model on a specific device
bbox3D_dectector_compile_job = hub.submit_compile_job(
    model=traced_bbox3D_dectector_model ,
    device=device,
    input_specs=bbox3D_dectector_model.get_input_spec(),
)

# Get target model to run on-device
bbox3D_dectector_target_model = bbox3D_dectector_compile_job.get_target_model()

Step 2: Performance profiling on cloud-hosted device

After compiling models from step 1. Models can be profiled model on-device using the target_model. Note that this scripts runs the model on a device automatically provisioned in the cloud. Once the job is submitted, you can navigate to a provided job URL to view a variety of on-device performance metrics.

bbox2D_dectector_profile_job = hub.submit_profile_job(
    model=bbox2D_dectector_target_model,
    device=device,
)
bbox3D_dectector_profile_job = hub.submit_profile_job(
    model=bbox3D_dectector_target_model,
    device=device,
)

Step 3: Verify on-device accuracy

To verify the accuracy of the model on-device, you can run on-device inference on sample input data on the same cloud hosted device.

bbox2D_dectector_input_data = bbox2D_dectector_model.sample_inputs()
bbox2D_dectector_inference_job = hub.submit_inference_job(
    model=bbox2D_dectector_target_model,
    device=device,
    inputs=bbox2D_dectector_input_data,
)
bbox2D_dectector_inference_job.download_output_data()
bbox3D_dectector_input_data = bbox3D_dectector_model.sample_inputs()
bbox3D_dectector_inference_job = hub.submit_inference_job(
    model=bbox3D_dectector_target_model,
    device=device,
    inputs=bbox3D_dectector_input_data,
)
bbox3D_dectector_inference_job.download_output_data()

With the output of the model, you can compute like PSNR, relative errors or spot check the output with expected output.

Note: This on-device profiling and inference requires access to Qualcomm® AI Hub. Sign up for access.

Deploying compiled model to Android

The models can be deployed using multiple runtimes:

  • TensorFlow Lite (.tflite export): This tutorial provides a guide to deploy the .tflite model in an Android application.

  • QNN (.so export ): This sample app provides instructions on how to use the .so shared library in an Android application.
