Unable import numpy

[boxfox]

I can't import numpy.

jep.JepException: <type 'exceptions.ImportError'>: 

Importing the multiarray numpy extension module failed.  Most

likely you are trying to import a failed build of numpy.

If you're working with a numpy git repo, try `git clean -xdf` (removes all

files not under version control).  Otherwise reinstall numpy.

It sounds like the numpy build did not go well.  Did you try cleaning and rebuilding it?  If you run python from a terminal and import numpy there, does that work?

I am also getting the same issue with JEP 3.7.1 with python 3.5.2

I tried reinstalling numpy with pip and I still get the same issue. numpy seems to be working fine in the shell.

Here is my stack trace :

Jep comes with a shell script(called jep) that gets installed in the python bin directory. Have you tried running this script and seeing if you are able to import numpy? I suspect that you need to include libpython in LD_PRELOAD because the numpy *.so does not declare its dependency on libpython, if this is your problem then the jep script should work and you can look in the script for an example of how to set LD_PRELOAD. There is also abrief discussion of LD_PRELOAD on the wiki.

Thank you! Setting LD_PRELOAD did it.

LD_PRELOAD needs to be set to the full path of the libpython shared object, the file name should be similar to libpython3.5m.so. Since the exact path is different depending on your configuration I would recommend shust copy the value out of the jep script that is installed with jep.
