the local wheel file specified in the `requirements_lock_<python_version>.txt`.

Packages are imported one by one in alphabetical order during runtime.

The test doesn't identify package's order-dependent issues; for instance,
importing "tf.foo" followed by "tf.bar" won't reveal that "tf.bar" depends on
"tf.foo" being imported first.

The `_api/v2/api_packages.txt` file is generated during the TensorFlow API v2

  // Runtime. This is necessary to decouple runtime-dependent

    *   Code that uses `isinstance(x, tf.Tensor)` instead of `tf.is_tensor` when
        checking Keras symbolic inputs/outputs should switch to using
        `tf.is_tensor`.
    *   Code that is overly dependent on the exact names attached to symbolic
        tensors (e.g. assumes there will be ":0" at the end of the inputs,
        treats names as unique identifiers instead of using `tensor.ref()`,
        etc.) may break.
