title: Permission denied: netcdf4 python module
body: <p>I have got a big problem of using the netcdf4 python module. My error is this:</p>
  
  <pre><code>Traceback (most recent call last):
    File "convert_lmkCosmoCols.py", line 264, in &lt;module&gt;
      ncdf_file= netCDF4.Dataset(pathNCDF+filenameNCDF+'.nc',mode='w',format='NETCDF4')

  OSError: Permission denied
  </code></pre>
  
  <p>I have installed the hdf5 library like it is described on this site:
  <a href="https://code.google.com/archive/p/netcdf4-python/wikis/UbuntuInstall.wiki" rel="nofollow noreferrer">https://code.google.com/archive/p/netcdf4-python/wikis/UbuntuInstall.wiki</a>
  and installed the netcdf4 library with this command: </p>
  
  <pre><code>sudo pip3 install netcdf4
  </code></pre>
  
  <p>I know I can use anaconda but I had a problem with its download an I prefer to avoid install anaconda.</p>
  
  <p>I use the python3.5.2 Version. First I updated python to 3.6 but then my ubuntu (Version 16.04) got broken and I only have solved it by reinstallation of the whole system. </p>
  
  <p>Can anyone help me, please?</p>
