Failed to build numpy - NumPy 1.21.2 may not yet support Python 3.10

I am trying to install ML Agents following these instructions

python -m pip install ./ml-agents-envs

error: subprocess-exited-with-error
× Building wheel for numpy (pyproject.toml) did not run successfully.

╰─> [287 lines of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.

Bumping the required version of numpy in the ml-agents\ml-agents-envs\setup file to 1.23.1 seems to have worked:

Before:
install_requires=[
"cloudpickle",
"grpcio>=1.11.0,<=1.48.2",
"Pillow>=4.2.1",
"protobuf>=3.6,<3.20",
"pyyaml>=3.1.0",
"gym>=0.21.0",
"pettingzoo==1.15.0",
"numpy==1.21.2",
"filelock>=3.4.0",
],

After:
install_requires=[
"cloudpickle",
"grpcio>=1.11.0,<=1.48.2",
"Pillow>=4.2.1",
"protobuf>=3.6,<3.20",
"pyyaml>=3.1.0",
"gym>=0.21.0",
"pettingzoo==1.15.0",
"numpy==1.23.1",
"filelock>=3.4.0",
],

After running >mlagents-learn --help
I get this error (NumPy doesn't initialize - do you have the same issue?):

[W ..\torch\csrc\utils\tensor_numpy.cpp:77] Warning: Failed to initialize NumPy: module compiled against API version 0x10 but this version of numpy is 0xf (function operator ())

[mikehaojiang]

After some digging: numpy==1.23.1 will fix it

@miguelalonsojr please update the setup.py in ml-agents/ml-agent-envs/ folder - thank you!

[sheslkw]

I got this problem today too. Thank you ! I think it is a mistake in the setup.py.

[miguelalonsojr]

This has been fixed on the develop branch.

[Thomasphifer]

Updated my comment to say numpy 1.23.1 worked best. Thanks!

[quakerntj]

Thanks. Changed to 1.23.1 work for my environment.

[f20500909]

thanks ,change numpy version to 1.23.1 in setup.py slove this problem!

Dear developer

Yet not changed in GitHub.
Today, three hours have melted away.

[Serch24]

1.23.1 works for me.
The installation guide should at least mention that we have to modify setup.py and change it!
