title: netCDF4 import not being found by Python
body: <p>I need to use the netCDF4 module in order to do some processing. I have followed the steps on this <a href="http://unidata.github.io/netcdf4-python/" rel="noreferrer">guide</a> and also tried used anaconda2 as recomended on this <a href="https://stackoverflow.com/questions/31471751/how-can-i-install-netcdf4-python-to-ubuntu14-04">post</a>.</p>
  
  <p>netCDF4 seems to be installed, as i can run <code>nc-config --version</code> and obtain:</p>
  
  <pre><code>netCDF 4.4.0-rc2
  </code></pre>
  
  <p>Although, when i try to import netCDF4 in python with:</p>
  
  <pre><code>from netCDF4 import Dataset
  </code></pre>
  
  <p>It Returns:</p>
  
  <pre><code>Traceback (most recent call last):
    File "test.py", line 2, in &lt;module&gt;
      from netCDF4 import Dataset
  ImportError: No module named netCDF4
  </code></pre>
  
  <p>I have all dependencies installed. Cython, numpy and h5py. <br>
  It was working last night, before i turned off the PC. When i came back this morning, it just would not work. So if i have netCDF4 installed and can check it's version, how come python is not recognizing it as a module?</p>
