PROBLEM DESCRIPTION
I'm getting this error while calling a python script :
Traceback (most recent call last): File "/path/t/file/file.py", line 61, in <module> from sklearn.externals import joblib File "/anaconda2/lib/python2.7/site-packages/sklearn/__init__.py", line 20, in <module> import logging File "/anaconda2/lib/python2.7/logging/__init__.py", line 26, in <module> import sys, os, time, cStringIO, traceback, warnings, weakref, collections File "/anaconda2/lib/python2.7/weakref.py", line 14, in <module> from _weakref import ( ImportError: cannot import name _remove_dead_weakref Failed to load file As stated in the error log, this happens when I import :
from sklearn.externals import joblib NOTES
NOTE 1: calling import sklearn alone also produces this error.
NOTE 2: Running without any other import statements and the rest of the code in the file commented out also produces the error
NOTE 3: Objective-C code is calling this python file via the Python C API (https://docs.python.org/2/c-api/index.html). This works perfectly on another machine with the exact same specs and OS (see details below).
NOTE 4: There is no error if I call Python from the terminal then import sklearn OR from sklearn.externals import joblib (Without calling from objective-C)
NOTE 5: I don't think I have any virtual environments installed. I've tried calling pyenv, pyvenv and virtualenv on the terminal. Always getting -bash: pyvenv: command not found
DETAILS
Both machines I've tried this on are MacBook Pros with identical specs running Mac OS 10.13. (The code works on one of them and fails on the other)
I've tried this on the machine the code fails on :
I've added the following lines to both (a) the script called by the executable AND (b) on the python CLI on the terminal :
print ">>>>>>>>>"+str(sys.executable) print ">>>>>>>>>"+str(sys.version) print "++++++++++++++++++++++++++++++++++++++++++++++++++++" for p in sys.path: print p Output from the script that's failing :

Try to uninstall, then install again your package:
conda uninstall scikit-learn

Try following the below commands. I faced a similar issue I was able to resolve it using:
sudo pip uninstall scikit-learnsudo pip install -U scikit-learn
Make sure following dependencies are met: Scikit-learn requires:
Python (>= 2.7 or >= 3.3) NumPy (>= 1.8.2), SciPy (>= 0.13.3)
Also checkout this Link.
For Note5: pyenv command does not exist in Python 2. You can use virtualenv instead.
