[SOLVED] python-mpi4py package not working

It looks like python-mpi4py package is not working.

[glow@GlowArch ~]$ sudo pacman -S python-mpi4py
warning: python-mpi4py-3.0.2-1 is up to date -- reinstalling [...]

(1/1) reinstalling python-mpi4py                                                               [########################################################] 100%

>>> import mpi4py
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'mpi4py'
>>> 

python2-mpi4py is working fine though.

Am I doing something wrong ?

Re: [SOLVED] python-mpi4py package not working

Where is your `python` from?  Are you using [testing]?

mpi4py works fine here, but I have python from [extra], yours is newer.

My bad, I enabled [testing] but not [community-testing], so the mpi4py package from community was not working with the python from testing. Thanks Trilby.
