Does MushroomRL support environment parallelization. about mushroom-rl HOT 1 CLOSED

No, you cannot use environment parallelization in mushroom.
It's also not planned to be implemented in the short term. There are many software reasons that bring us to this decision.
The fact that we don't support parallel execution gives us a very clean and simple framework for every algorithm. As this is a research tool, having good and easy-to-extend implementations is more valuable than speed: indeed in research, you need to run multiple runs with different seeds, so the parallelization is useless.

What you can do, is to implement your own core that does parallel execution of policies. However, we will not merge it in mushroom, at least in the short term, as this brings a lot of software issues and usage issues that we don't want to handle.
