  Python compilation expects using the tarball based compilation strategy from above.
  +
  +## Testing using Python backend
  +
  +Torch-TensorRT supports testing in Python using [nox](https://nox.thea.codes/en/stable)
  +
  +To install the nox using python-pip
  +
  +```
  +python3 -m pip install --upgrade nox
  +```
  +
  +To list supported nox sessions:
  +
  +```
  +nox --session -l
  +```
  +
  +Environment variables supported by nox
  +
  +```
  +PYT_PATH - To use different PYTHONPATH than system installed Python packages
  +TOP_DIR - To set the root directory of the noxfile
  +USE_CXX11 - To use cxx11_abi (Defaults to 0)
  +USE_HOST_DEPS - To use host dependencies for tests (Defaults to 0)
  +```
  +
  +Usage example
  +
  +```
  +nox --session l0_api_tests
  +```
  +
  +Supported Python versions:
  +```
  +["3.7", "3.8", "3.9", "3.10"]
  +```
