`pip install -r requirements.txt` got error

[liqwang]

My environment is linux-x64 with Python 3.9.18

After I execute pip install -r requirements.txt, I got the following error caused by dependency conflict:

The conflict is caused by:
    The user requested numpy==1.21.2
    array2gif 1.0.4 depends on numpy
    contourpy 1.0.6 depends on numpy>=1.16
    gym 0.21.0 depends on numpy>=1.18.0
    imageio 2.13.3 depends on numpy
    magent 0.1.14 depends on numpy>=1.18.0
    matplotlib 3.6.2 depends on numpy>=1.19
    mkl-fft 1.3.1 depends on numpy<1.23.0 and >=1.22.3

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Besides the dependency conflict problems, there are other problems in requirements.txt:

• prl==0.1.0 isn't a valid version: https://pypi.org/project/prl/#history https://github.com/deligentfool/mfrl_pytorch/blob/cc67da79bac2717f3b275305c14e69967b72becb/requirements.txt#L45
• pip isn't neccessary https://github.com/deligentfool/mfrl_pytorch/blob/cc67da79bac2717f3b275305c14e69967b72becb/requirements.txt#L44
• torchaudio==0.7.0a0+a853dff isn't consistent with the official install command, the correct version should be torchaudio==0.7.2 https://github.com/deligentfool/mfrl_pytorch/blob/cc67da79bac2717f3b275305c14e69967b72becb/requirements.txt#L73

I try to fix the above dependency conflict error by changing numpy version to 1.22.3

- numpy==1.21.2
+ numpy==1.22.3

Then I got another dependency conflict error:

The conflict is caused by:
    The user requested numpy==1.22.3
    array2gif 1.0.4 depends on numpy
    contourpy 1.0.6 depends on numpy>=1.16
    gym 0.21.0 depends on numpy>=1.18.0
    imageio 2.13.3 depends on numpy
    magent 0.1.14 depends on numpy>=1.18.0
    matplotlib 3.6.2 depends on numpy>=1.19
    mkl-fft 1.3.1 depends on numpy<1.23.0 and >=1.22.3
    mkl-random 1.2.2 depends on numpy<1.25.0 and >=1.24.3

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
