"ERROR: Could not build wheels for nnmnkwii which use PEP 517 and cannot be installed directly"

[oatsu-gh]

I tried to install nnmnkwii via .bat which has the following command

python-3.8.10-embed-amd64\python.exe -m pip install --upgrade nnmnkwii

and faced an error

ERROR: Could not build wheels for nnmnkwii which use PEP 517 and cannot be installed directly.

When I tried the command with PowerShell, nnmnkwii can be installed.

• Could you prepare the package using PEP518?
• How can I avoid the error?

I have the same issue as @maahhi

@sathvikkurap Numpy just announced they upgraded to version 2.0.0. I think this issue occurred due to the out-of-date numpy API used in this project. Try to edit the pyproject.toml, replace the specific numpy bigger than 1.19.3 and not equal to 2.0.0. I encountered the same issue but solved it after using the above tricky method.
