The Read the Docs build is done now! Still fails importing, but as I said it looks like a problem with the aurosummary templates

[astrojuanlu]

As I explained in sphinx-doc/sphinx#7989, the WARNING: [autosummary] failed to import 'd3rlpy.algos.AWAC': no module named d3rlpy.algos.AWAC doesn't actually mean that the d3rlpy.algos.AWAC module is being imported. Rather, it is masking a deeper error:

However, launching a Python interpreter doesn't have this problem. I think I got how to fix it, will push one more commit.

@takuseno problem fixed, have a look at the build logs 👍🏽

Thanks for the change! I'll merge this when the test has passed.
