numpy undefined symbol: PyFPE_jbuf

Issue

I am trying to use the One Million Song Dataset, for this i had to install python tables, numpy, cython, hdf5, numexpr, and so.

Yesterday i managed to install all i needed, and after having some troubles with hdf5, i downloaded the precompiled binary packages and saved them in my /bin folder, and the respective libraries in /lib , after that i tested this python script : http://labrosa.ee.columbia.edu/millionsong/sites/default/files/tutorial1.py.txt

and it worked fine, to be clear the way i made it work was to first run the script and start installing the needed dependencies, but today i restarted my laptop and it didn’t work, now it throws me this error on the console :

python2.7 script.py 

returns :

import numpy as np # get it at: http://numpy.scipy.org/
from . import random
from .mtrand import *
ImportError: /home/francisco/.local/lib/python2.7/site-packages/numpy/random/mtrand.so: undefined symbol: PyFPE_jbuf

seems to me that there is a missing variable in such file, my guess is that the script is looking for the numpy library in the wrong place, since i made so many failed installations maybe i broke something and it only worked out because it was loaded in the temporal memory of the computer.

I tried installing Anaconda, and i created a new environment and installed the packaged with the anaconda package manager, and even thought i listed all packaged and it returns :

i still get the same error. I really need help and don’t know what else to try. Thanks.

Solution

I had the same problem, probably you have installed numpy without Anaconda, so there is a conflict because of this, which numpy to use: that one installed with pip or with conda. When I removed non-Anaconda numpy, error gone.

pip uninstall numpy
