The reason I originally loaded python_2.7.2 was to avoid the error message below. Now that python_2.7.2 is unloaded this message is back ...% module unload python_2.7.2
% python setup.py develop
yt currently requires Python version 2.7
certain features may fail unexpectedly and silently with older versions.%As the next step I will try to repeat the whole process from scratch w/o using module load pkgsrc/2015Q2. Instead, I will just use standalone mercurial installation to see if this helps.

Following your suggestions, I replaced "conda build conda-recipes/yt" with "conda install yt.” I am also able to do "conda install pip" w/o problem.

Please either install yt from a provided, release tarball,

You may be able to accomplish this by typing:
pip install -U CythonIs there anything obvious in the above command sequence that is wrong? I am wondering if this problem has anything to do with how you setup various modules on Pleiades. For example, in order to use mercuria,l I do "module load pkgsrc/2015Q2” I also do “module load python_2.7.2” The pkgsrc/2015Q2 package loads a number of obsolete modules and perhaps they are messing things up?Yes, that is possible.You want to make sure that you are running the miniconda python and not the python loaded by the module. You can check by doing "which python". If you're using miniconda, you want to unload the python_2.7.2 module.Thanks,Mateusz

miniconda3/bin/conda build conda-recipes/ytHere you want to do "conda install yt" to get all of yt's dependencies. From there you can install the development version of yt. You can "conda install" must python packages.As desika mentioned, you can also install pip with "conda install pip".I'd caution against using the full anaconda distribution since anaconda's MPI will shadow the system MPI installation unless you explicitly remove it.This resulted in:Cython is a build-time requirement for the source tree of yt.

pip install -U Cythonwhich I am not able to install via "pip install -U Cython." So this is essentially the same error message I got when I attempted to install yt using the method described in my previous e-mail. Any idea what may still be wrong?Thanks,Mateusz

You could also use the yt install script, although you might have issues with that if Pleiades has an older (insecure) version of OpenSSL installed, which is sadly quite common on supercomputers these days...Personally, I set up my python environment on Pleiades using miniconda.-Nathan_______________________________________________On Mon, Oct 19, 2015 at 11:23 AM, Mateusz Ruszkowski <mateuszr@umich.edu> wrote:Hi,I am trying to install yt on Pleiades.
