<div>Hi, Kevin:</div>
<div><br>
</div>
<div>Thank you so much for getting back with me!</div>
<div><br>
</div>
<div>I am trying anaconda on my MacBook Pro.</div>
<div><br>
</div>
<div>One question: Can anaconda be installed on Windows system with the PyNGL and PyNIO, pygrib to work? Or it has to be on a virtual machine. Our lab have all windows machines. Thanks!</div>

Hi,
<div class=""><br class="">
</div>
<div class="">Is there any chance you could possibly use Anaconda/Miniconda on these virtual machines instead of Enthought Canopy? As far as I am aware, there is no easy way for us to create and distribute a version of our software that is built against Enthought
Canopy’s libraries.</div>
<div class=""><br class="">
</div>
<div class="">However, we do have up-to-date versions PyNGL and PyNIO (and NCL) available on the "conda-forge” Anaconda channel, which also hosts many other commonly used scientific packages (including pygrib!). Unfortunately, Anaconda and Enthought Canopy
may not be compatible; in order for Anaconda to work properly, its provided python needs to be the “default” python.</div>
<div class=""><br class="">
</div>
<div class="">We have information regarding the installation of Anaconda/Miniconda on the PyNGL/PyNIO download page:
<a href="https://www.pyngl.ucar.edu/Download/" class="">https://www.pyngl.ucar.edu/Download/</a></div>
<div class=""><br class="">
</div>
<div class="">In order to use the recommended "conda-forge" versions (different from the example on the linked page), create a conda environment using a command such as:</div>
<div class=""><font face="Courier New" class="">conda create --name <env_name> --channel conda-forge pynio pyngl</font></div>
<div class=""><br class="">
</div>
<div class="">and then activate the environment:</div>
<div class=""><font face="Courier New" class="">source activate <env_name></font></div>
<div class=""><br class="">
</div>
<div class="">Note that “<env_name>” can be whatever you would like your conda environment to be named; for example, the linked documentation above uses “pyn_test”.</div>
<div class=""><br class="">
</div>
<div class="">If using Anaconda/Miniconda is not possible, then we will have to further troubleshoot building PyNIO from source code.</div>
<div class=""><br class="">
</div>
<div class="">Please let us know if this information helps!</div>
<div class=""><br class="">
</div>
<div class="">Thanks,</div>
<div class="">Kevin</div>
