----------------------------------

Hi, I meet the same issue when trying the flink runner, what am I doing right now is adding my "pip install xxx" in ~/beam/sdks/python/container/base_image_requirements.txt to make it work, what's the correct way of doing it other than change the source code?

> It's pretty common that Python scripts require extra dependencies, even the tensorflow model analysis TFMA example requires a different version of TF than the one we install by default. While users can roll their own container or edit the Dockerfile, it would probably be useful to provide an easier path to integrating their dependencies.
> While we support automatically installing the dependencies at runtime on the workers, this can be very slow, especially for things like tensorflow, arrow, or other numeric heavy code.
> Another alternative could be a simple script to augment the existing base image.
