How to do regression test

This tutorial describes how to do regression test. The deployment configuration file contains codebase config and inference config.

1. Python Environment

pip install -r requirements/tests.txt

If pip throw an exception, try to upgrade numpy.

pip install -U numpy

2. Usage

python ./tools/ \
    --codebase "${CODEBASE_NAME}" \
    --backends "${BACKEND}" \
    [--models "${MODELS}"] \
    --work-dir "${WORK_DIR}" \
    --device "${DEVICE}" \
    --log-level INFO \
    [--performance  -p] \
    [--checkpoint-dir "$CHECKPOINT_DIR"]


  • --codebase : The codebase to test, eg.mmdet. If you want to test multiple codebase, use mmpretrain mmdet ...

  • --backends : The backend to test. By default, all backends would be tested. You can use onnxruntime tesensorrtto choose several backends. If you also need to test the SDK, you need to configure the sdk_config in tests/regression/${codebase}.yml.

  • --models : Specify the model to be tested. All models in yml are tested by default. You can also give some model names. For the model name, please refer to the relevant yml configuration file. For example ResNet SE-ResNet "Mask R-CNN". Model name can only contain numbers and letters.

  • --work-dir : The directory of model convert and report, use ../mmdeploy_regression_working_dir by default.

  • --checkpoint-dir: The path of downloaded torch model, use ../mmdeploy_checkpoints by default.

  • --device : device type, use cuda by default

  • --log-level : These options are available:'CRITICAL', 'FATAL', 'ERROR', 'WARN', 'WARNING', 'INFO', 'DEBUG',  'NOTSET'. The default value is INFO.

  • -p or --performance : Test precision or not. If not enabled, only model convert would be tested.


For Windows user:

  1. To use the && connector in shell commands, you need to download PowerShell 7 Preview 5+.

  2. If you are using conda env, you may need to change python3 to python in because there is python3.exe in %USERPROFILE%\AppData\Local\Microsoft\WindowsApps directory.


  1. Test all backends of mmdet and mmpose for model convert and precision

python ./tools/ \
    --codebase mmdet mmpose \
    --work-dir "../mmdeploy_regression_working_dir" \
    --device "cuda" \
    --log-level INFO \
  1. Test model convert and precision of some backends of mmdet and mmpose

python ./tools/ \
    --codebase mmdet mmpose \
    --backends onnxruntime tensorrt \
    --work-dir "../mmdeploy_regression_working_dir" \
    --device "cuda" \
    --log-level INFO \
  1. Test some backends of mmdet and mmpose, only test model convert

python ./tools/ \
    --codebase mmdet mmpose \
    --backends onnxruntime tensorrt \
    --work-dir "../mmdeploy_regression_working_dir" \
    --device "cuda" \
    --log-level INFO
  1. Test some models of mmdet and mmpretrain, only test model convert

python ./tools/ \
    --codebase mmdet mmpose \
    --models ResNet SE-ResNet "Mask R-CNN" \
    --work-dir "../mmdeploy_regression_working_dir" \
    --device "cuda" \
    --log-level INFO
