About the full distribution of levels

Does "the full distribution of levels" equal to "num_level=0" ?
I can't find any definition from your paper or comments from your code. (If I missed, I'm sorry)
Yes, 0 or unset (which defaults to 0) should result in INT32_MAX levels: https://github.com/openai/procgen/blob/master/procgen/src/vecgame.cpp#L287 which is about 2 billion.
The README says "num_levels=0 - The number of unique levels that can be generated. Set to 0 to use unlimited levels." Which is slightly inaccurate since it's not "unlimited", changing the docs to say "the full distribution of levels" may make more sense.
Thank you very much for your answer.

Yes, I definitely agree. "unlimited" made me confused.

Hi! I hope to know whether it means that we have to train and test on all of the set having 2 billion levels, as the paper said, 'When evaluating sample efficiency, we train and test agents on the full distribution of levels in each environment' (If I missed something important, I'm sorry)
I believe that means that each episode selects a random level from the 2 billion, not that all 2 billion are used since there should be fewer than 2 billion episodes.
