invalid-action-masking: [Bug?] An error when installing gym_microrts

Hi,

Thanks for the great work. I am interested in this paper and attempt to reproduce the experiments to understand more.

One error is that Multiple top-level packages discovered in a flat-layout: ['maps', 'docker', 'experiments', 'gym_microrts']. when installing gym_microrts. I guess this is caused by automatic discovery of the setuptools as not explicitly specified in setup.py.

This workaround works for me: adding py_modules=['gym_microrts'] in the setup.py.

Specifically, I modified .../envs/act_mask/src/gym-microrts/setup.py to:

from setuptools import setup

setup(name='gym_microrts',
      version='0.1.0',
      install_requires=['gym', 'dacite', 'jPype1', 'hilbertcurve'],
      py_modules=['gym_microrts']
)

Previously, it is:

from setuptools import setup

setup(name='gym_microrts',
      version='0.1.0',
      install_requires=['gym', 'dacite', 'jPype1', 'hilbertcurve']
)

The environment specifications:

• anaconda: v4.11.0
• Python: 3.8

        To avoid accidental inclusion of unwanted files or directories,
        setuptools will not proceed with this build.
        
        If you are trying to create a single distribution with multiple packages
        on purpose, you should not rely on automatic discovery.
        Instead, consider the following options:
        
        1. set up custom discovery (`find` directive with `include` or `exclude`)
        2. use a `src-layout`
        3. explicitly set `py_modules` or `packages` with a list of names
        
        To find more information, look for "package discovery" on setuptools docs.
