Re: Python subprocess fails to execute Pip-installed module / Packaging Python Ray

[Pradana Adrinusa AUMARS <paumars@courrier.dev>]

I'm in the process of packaging Ray for Python.

Here is the current SCM configuration:

(use-modules (guix packages)
	     (guix download)

	     (gnu packages python-build)
	     (gnu packages protobuf)
	     (gnu packages machine-learning)
	     (gnu packages python-science)
	     (gnu packages python-web)
	     (gnu packages python-xyz))

When I build the package, pip tries to download from
pypi.org/simple/psutil, even though it's written as an input in this
configuration. The output gives this error:

warning: build_py: byte-compiling is disabled, skipping.

running build_ext

...
ERROR: Could not find a version that satisfies the requirement psutil (from versions: none)
ERROR: No matching distribution found for psutil

Has there been a similar issue with Python packages with psutil as an
input or with pip not properly finding dependencies like this?

Thanks
