5 years ago I ran into this problem as well. The problem is that setup.py uses packages=find_packages() to determine which directories to include when installing. It only includes directories with __init__.py which the assets directories do not have. One simple fix is to install the package by cloning the repository locally and then installing with pip install -e .. This works because all files, even those not included by find_packages will be available. I ran into this problem by installing using: pip install git+https://github.com/vitchyr/multiworld and based on the traceback you posted it looks like you did a similar thing. The fix would be to manually include the assets directory in the setup call.

I ran the code from the rlkit ,but it seems that something is missing in the environment.
