Bug: 'numpy.random._generator.Generator' object has no attribute 'randint'

[xinyu-site]

Hello,

I encountered an issue while using your repository. When attempting to run the code, I encountered the following error:

AttributeError: 'numpy.random._generator.Generator' object has no attribute 'randint'
It seems that the error is caused by the missing randint attribute in the numpy.random.Generator object. According to my understanding, the randint method should be available in newer versions of NumPy.

I suspect that this issue may be related to the version of NumPy being used. Therefore, I have a few questions:

What version of NumPy did you use during the development and testing of this repository?
Could you provide a specific NumPy version number that I can try, either to downgrade or upgrade my own NumPy version to potentially resolve this issue?
If this issue is indeed related to the NumPy version, have you considered updating the code to accommodate a wider range of NumPy versions?
Thank you for your help and support! Please let me know if you need any further information.

Hi @xjtueryx, thanks for reporting this! The compact layer for numpy.random.Generator was removed in Gym 0.26.0 (see openai/gym#3022). Could you try:

pip3 install 'gym<0.26.0'

I would range-pin the Gym version or find a more general solution.
