EfficientZeroV2

[redzhepdx]

I think the current efficient zero implementation is focused on the first paper. Last year they announced EfficientZeroV2.
https://github.com/Shengjiewang-Jason/EfficientZeroV2. According to the paper they expanded existing efficient zero with Gumbel sampling and additional dynamics computation.

Are you planning to bring efficient-zero-v2 updates into this repository?

Thank you for your suggestion. Yes, our current implementation is based on the original EfficientZero. We are very interested in integrating the improvements from EfficientZeroV2 into LightZero, although this may be part of our long-term plans for the future. If any community contributors are willing to incorporate it into LightZero, we would greatly appreciate it and provide comprehensive discussion support throughout the reproduction process.
