pyBigWig fails to find numpy installation when installing from PyPI #131

Closed EricR86 closed 2 years ago

EricR86 commented 2 years ago

I cannot reliably get pyBigWig to install with numpy features enabled as a dependency. In a docker image with numpy pre-installed I can get two different outcomes depending on whether or not I install from source or not.

For examples in the source directory (on current HEAD), if I run: python3 -m pip install -vv --upgrade --force-reinstall . numpy features are enabled

Outside the source directory if I run: python3 -m pip install -vv --upgrade --force-reinstall pybigwig numpy features are disabled

This is very problematic to having pyBigWig as a dependency especially when the numpy features are needed.

Thanks for your time.

That's very confusing. It should look for numpy if it can run from numpy.distutils.misc_util import get_info. Can you try running python3 -c "from numpy.distutils.misc_util import get_info; print('worked')"? It should print "worked" in both cases.

Both on an install with numpy features enabled and disabled both print the same message:

python3 -c "from numpy.distutils.misc_util import get_info; print('worked')"
<string>:1: DeprecationWarning: 

  `numpy.distutils` is deprecated since NumPy 1.23.0, as a result
  of the deprecation of `distutils` itself. It will be removed for
  Python >= 3.12. For older Python versions it will remain present.
  It is recommended to use `setuptools < 60.0` for those Python versions.

worked

Which is what I expected. I specifically made sure numpy was in the environment in both cases. Even if I run the python3 -m pip install -vv --upgrade --force-reinstall pybigwig command with the additional --no-deps option (and numpy already installed) to ensure nothing gets re-installed, it still fails to build with numpy features enabled.

What happens if you run pip cache remove pyBigWig before installing from pypi? I got it installed using numpy (numpy 1.23.3) in either case, but I wonder if it's just cached a build without numpy in your case.

EricR86 commented 2 years ago

You're correct. --force-reinstall apparently still uses the cached pypi version. I had installed with pyBigWig as a dependency and it did not detect numpy which is its own issue. Force reinstalling apparently used the cached version built locally.

Caching is the cause of and solution to all of life's problems :P
