requirements, why?

[danpovey]

@csukuangfj why does our requirements file have detailed requirements on the numpy and associated python versions?

"Cython; sys_platform=='win32' and python_version >= '3.10'",
"numpy<=1.19.5; python_version >= '3.6' and python_version < '3.7'",
"numpy<=1.21.6; python_version >= '3.7' and python_version < '3.8'",
"numpy<1.23.0; python_version >= '3.8' and python_version < '3.10'",
"numpy; python_version >= '3.10'",

Is this just what we've tested? I think we are basically only using the dlpack or whatever, no detailed features, I think?
It seems to sometimes cause problems e.g. when lhotse wants to update numpy, and it suggests a version that isn't within this requirements matrix.

Because it has errors when using GitHub actions to compile it.

I am retesting it and see if we can remove that constraint.

Should be fixed by #58
Please use
