No module named 'info' on fresh Python 3 installation

I did a fresh python3 installation on OSX via homebrew:

brew install python3

Then I created a virtual environment for my project and installed scipy and scikits.samplerate: 

virtualenv -p /usr/local/bin/python3 pythen_env 
pip install scipy
pip install scikits.samplerate

However, when I try to import a function from scikits.samplerate, I get the following error: 

>>> from scikits.samplerate import resample
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/my/project/path/pythen_env/lib/python3.6/site-packages/scikits/samplerate/__init__.py", line 4, in <module>
    from info import __doc__
ModuleNotFoundError: No module named 'info'

Info happens to be the first module from the package itself that is imported in __init__.py.

Strangely, the module info.py exists in /my/project/path/pythen_env/lib/python3.6/site-packages/scikits/samplerate/:

ls /my/project/path/pythen_env/lib/python3.6/site-packages/scikits/samplerate/
__init__.py    setup.py        tests        __pycache__
info.py        setuphelp.py    version.py

The error also happens when I try the same without virtualenv, as well as for other packages. How could I start to debug this issue?

Solution

  • The problem seems to be that the package scikits.samplerate does not support Python 3.X (see issue). However, there is a fork which supports Python 3.X. You can install it via

    $ pip install git+https://github.com/gregorias/samplerate.git

    As always: people can make anything they like in repositories. I did not check which changes gregorias made.
