title: Python AttributeError: module 'sklearn.externals.joblib.numpy_pickle' has no attribute 'NumpyArrayWrapper'
body: <p>I got a deep learning code in python (anaconda 4.2), on Ubuntu 16.04. It basically detects ad frames inside a video. When trying to run it, I get an error. How can I fix it? I'm not a python/anaconda guy myself.</p>
  
  <pre><code>from __future__ import absolute_import
  from __future__ import division
  from __future__ import print_function
  import time, cv2, librosa
  import skvideo.io
  import numpy as np
  import tensorflow as tf
  import subprocess, os, glob
  from sklearn.externals import joblib
  //...........
  clf_trained = joblib.load('/home/myuser/Desktop/Detection_module/trainsvm_mfcc.pkl') 
  //...........
  </code></pre>
  
  <p>And here are the errors:</p>
  
  <pre><code>​/home/myuser/anaconda3/lib/python3.5/site-packages/skvideo/__init__.py:356: UserWarning: avconv/avprobe not found in path:
