Enable to instal Magenta on WinPython 3.11

Question

I am encountering issue to install Magenta with my WinPython 3.11 installed on my external drive.

I have installed Microsoft Visual C++ Build Tools: specifically Desktop development with C++ only and Cython. I tried then to install Magenta and I got the following errors:

Possible solutions: 1. Declare '_cb_func' as 'noexcept' if you control the definition and you're sure you don't want the function to raise exceptions. 2. Use an 'int' return type on '_cb_func' to allow an error code to be returned. performance hint: src_rtmidi.pyx:219:5: Exception check on '_cb_error_func' will always require the GIL to be acquired.

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

× Encountered error while generating package metadata. ╰─> See above for output.

note: This is an issue with the package mentioned above, not pip. hint: See above for details.

I have upgraded Cython, installed the dependencies separately, I have installed wheels and tensorflow but when I went to install Magenta, I always got the same type of error - compilation and conflict issues with the python-rtmidi package.

I have a HP Probook with the following: Processor Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz 1.99 GHz Installed RAM 16.0 GB (15.9 GB usable)

Would anyone be so kind as to advice what I should do to resolve the issue and install Magenta? Thank you so much in advance.
