file for testing, such as:

* Ensuring the entire API is importable
* Testing downstream projects against the wheel

Ensure you have Bazel installed and accessible from your command line.

These tests use hermetic Python. They also require a built TensorFlow wheel file
and a requirements_lock file. The requirements_lock file is generated by the

    echo "buildifier formatting is recommended. Here are the suggested fixes:"

By default, the lowest supported version is used.

To set a different version, use the `TF_PYTHON_VERSION` environment variable,
e.g.

```
export TF_PYTHON_VERSION=3.11
```

To specify the version via a Bazel command argument, use the following:

```
--repo_env=TF_PYTHON_VERSION=3.11
```

#   You will need the NVIDIA Container Toolkit for GPU testing:

#   Note: if you interrupt a bazel command on docker (ctrl-c), you

#   Note: new files created from the container are owned by "root".
