<div>Hi, Bill and Kevin:</div>
<div><br>
</div>
<div>Good news! Finally, I got an environment that works! (before update Xcode)</div>
<div><br>
</div>
<div>The following was what I did:</div>
<div><br>
</div>
<div>
<div style="font-family: Calibri; font-size: medium; ">bash Downloads/<a href="http://anaconda2-4.2.0-macosx-x86_64.sh/" target="_blank">Anaconda2-4.2.0-MacO<wbr>SX-x86_64.sh</a><br>
conda update conda<br>
</div>
<div style="font-family: Calibri; font-size: medium; ">conda update -all<br>
</div>
<div style="font-family: Calibri; font-size: medium; "><br>
</div>
<div style="font-family: Calibri; font-size: medium; ">conda create -n metuse python=2.7 spyder basemap netcdf4</div>
<div style="font-family: Calibri; font-size: medium; ">source activate metuse<br>
conda install -c ncar -c khallock pynio pyngl<br>
</div>
<div style="font-family: Calibri; font-size: medium; "><br>
</div>
<div style="font-family: Calibri; font-size: medium; ">I have tested that PyNio, PyNGL, and basemap all works in both python and spyder. No problem, no warnings, etc. </div>
</div>
<div style="font-family: Calibri; font-size: medium; "><br>
</div>
<div style="font-family: Calibri; font-size: medium; ">Thanks for still keeping the versions at channels of ncar and khallock! </div>
<div style="font-family: Calibri; font-size: medium; ">The previous many tries somehow show that conda-forge is against me for now. With conda-forge, I tried only pynio and pyngl, no luck. I tried only pygrib, no luck. Spyder was also downgraded to 2.3.9. Pygrib
is still not working, even when I downloaded the zip file and install with pip. But, with pynio, I think can get around it for grib files.</div>
<div style="font-family: Calibri; font-size: medium; "><br>
</div>
<div style="font-family: Calibri; font-size: medium; ">Thank you for all your time, and again your great patience!</div>
<div style="font-family: Calibri; font-size: medium; ">Also thanks for the reminder of updating Xcode, I did that after the above worked. I guess it will be helpful in the long run.</div>
<div style="font-family: Calibri; font-size: medium; "><br>

<div dir="ltr">Hi Xinygang,
<div><br>
</div>
<div>The error message is indicating that you are missing __sincos_stret, which is probably something that is assumed to be on your Mac already, since it is associated with the compiler math libraries. Can you try installing (or reinstalling) XCode and the
command line tools to see if that fixes your problem. I know Apple just released an XCode update, and sometimes libraries need to get reinstalled manually after the update, usually via installing the command line tools. (Run "xcode-select --install" and
see if it prompts you to install the tools). </div>

<div>Dear Kevin and Bill:</div>
<div><br>
</div>
<div>I really appreciate your patience with me and help. I am kind of new to the python packages and just don't know how to interpret the error messages.</div>
<div>The following was what I did, considering your suggestions:</div>
<div><br>
</div>
<div>FIRST:</div>
<div>Deleted the anaconda2 directory along with .conda .condrc </div>
<div>Reinstalled anaconda2: bash Downloads/<a href="http://Anaconda2-4.2.0-MacOSX-x86_64.sh" target="_blank">Anaconda2-4.2.<wbr>0-MacOSX-x86_64.sh</a></div>
<div>condo update condo</div>
<div>conda update -- all</div>
<div><br>
</div>
<div>With these, python and spyder (newest version) starts well.</div>
<div><br>
</div>
<div>THEN: </div>
<div>conda config --add channels conda-forge # This makes the installation to search packages first from conda-forge #</div>
<div>
<div>conda create -n test -c conda-forge pynio pyngl netcdf4 basemap spyder</div>
<div>source activate test</div>
<div>python Downloads/Basemaps_US_01.py</div>
</div>
<div><br>
</div>
<div>TESTING RESULTS:</div>
<div>spyder (2.3.9) starts well, but running one of my code (tested okay in earlier installations) had problems with either matplotlib or basemap. So, I also run it from command line.</div>
<div>The problems are shown below. Right following it, is the attempt to import Nio directly from running python at command line:</div>

<div>Thanks,</div>

<div><br>
</div>
<div>P.s. I had a successful installation before on this computer. It was messed up when I tried to update the pyngl and pynio from condo-forge. However, I forgot how I installed them the first time. I might have installed from downloading the .zip files from
Github and then use pip. The only thing I didn't have was pygrib. This was the reason why I attempted to update my previous working system (all under root env), because on a Ubuntu virtual machine system, all three of pyngl pynio and pygrib were successfully
installed and can be imported without problem. While keep trying an easy install, I will see if I can repeat my old installation.</div>
<div><br>
</div>
<div>I really need an easy procedure, so that the students would be able to follow on their own Mac system. For Windows machine, the virtual machine I created can be imported into their VirtualBox.</div>
<div><br>
</div>
<div>Thanks again for your help!</div>

<div><br>
</div>
<div>
<div>Instead of creating these two separate environments and then trying to combine them, could you please try creating a single environment using the following command:</div>
</div>
<div>
<div style="font-family:Helvetica;font-size:12px"><font face="Courier New">conda create -n pyn_testing -c conda-forge python=2.7 pynio pyngl netcdf4 basemap spyder</font></div>
</div>
<div>
<div style="font-family:Helvetica;font-size:12px"><font face="Courier New">source activate pyn_testing</font></div>
</div>
</div>
<div><br>
</div>
</div>
<div>Even though both of the environments work before combining them, I would expect them to fail due to incompatible versions of packages. For example, in your “metuse” environment you should have libnetcdf 4.4.1.1 from conda-forge installed as a dependency
of pynio; in your “condaX” environment, you’ll have libnetcdf 4.4.1 from the default channel installed as a dependency of netcdf4. This is just one example of the incompatibilities that can happen when installing from multiple channels. Again, it is important
to use “-c conda-forge” on any “conda create …”/“conda install …”/“conda update …” commands you may run for the environment you’re trying to create.</div>
<div><br>
</div>
</div>
<div>Also, I noticed that you chose to install the anaconda package when creating the condaX environment (in step II above). Installing the “anaconda” package is almost guaranteed to make your environment incompatible with most packages from the conda-forge
channel (including pynio and pyngl), as described in the previous paragraph. Is there a particular package included in “anaconda” that you need? I would try to list specific packages instead of “anaconda”, and I would try to install them from the conda-forge
channel (“-c conda-forge”) if possible.</div>
<div><br>
</div>
<div>I hope this helps!</div>
