title: python module import error when running, while imported fine in interactive mode
body: <p>I've created a clean python3.6 virtualenv in a native python2 environment via anaconda3, and I'm able to import some module in the interactive mode:</p>
  
  <pre><code>$ python
  Python 3.6.3 |Anaconda, Inc.| (default, Oct 13 2017, 12:02:49) 
  [GCC 7.2.0] on linux
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; from skimage.transform import resize
  &gt;&gt;&gt;
  </code></pre>
  
  <p>however, this seems to break when I run in a non-interactive mode by calling: </p>
  
  <pre><code>(py3)$ python filename.py
  ...
  File "path_to_module.py", line 6, in &lt;module&gt;
      from skimage.transform import resize
  ...
  ImportError: /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by path_to_pyenv/anaconda3/lib/python3.6/site-packages/matplotlib/_path.cpython-36m-x86_64-linux-gnu.so)
  </code></pre>
  
  <p>Note this error does not occur exclusively by importing this particular skimage module, so i guess this is a generic error. </p>
  
  <p>Anyone has an idea how to fix this? 
  Thanks!</p>
