New issue 3041: pypy3 import numpy fails unknown symbol PyGILState_Check
https://bitbucket.org/pypy/pypy/issues/3041/pypy3-import-numpy-fails-unknown-symbol
Johan Jönsson:
I am trying to install numpy \(both from source and via pip\). With
pypy-7.1.1-beta0 \(from the gentoo repositories\) I can build/install numpy,
however when I try to import numpy i get the following output
```
Python 3.6.1 (784b254d669919c872a505b807db8462b6140973, Jul 07 2019, 15:05:37)
[PyPy 7.1.1-beta0 with GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
And now for something completely different: ``it's nonsense all the way down,
and also all the way up''

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
1. Check that you expected to use Python3.6 from "/usr/bin/pypy3",
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy version "1.18.0.dev0+48efcc7" you're
trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
- If you're working with a numpy git repository, try `git clean -xdf`
(removes all files not under version control) and rebuild numpy.
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.
Original error was:
~/.local/lib/pypy3.6/site-packages/numpy/core/_multiarray_umath.pypy3-71-x86_64-linux-gnu.so:
undefined symbol: PyGILState_Check
