How did you solve this issue?

In fact, I found that this is caused by incompatible software versions. When I execute pip install rex-gym,, I found that the version of 0.17 was installed instead of the latest version. When I installed through the cloned package, I found that the software libraries would conflict with each other and cancelled the version limit of gym in the "requirements .txt" , that it can be installed smoothly, and rex-gym will be reinstalled to the latest version
