PySCeS on OSX High Sierra: nleq2 error

[bgoli]

Hi A student installed the Anaconda PySCeS package for OSX High Sierra 10.13.6 and is getting the following nleq2 error:

Has anyone with a Mac run into this problem before?

I can't reproduce this on OSX 10.13.3 in a fresh conda env, pysces installed with

conda install -c bgoli -c sbmlteam pysces

Everything seems to work and the nleq2 object does exist:

In [9]: m = pysces.model('pysces_test_branch1')
Assuming extension is .psc
Using model directory: /Users/jr/Pysces/psc

Out[13]: <fortran object>

In [14]: id(pysces.nleq2.nleq2)
Out[14]: 4758184104

Only difference I can see is that above is anaconda3 (albeit with a python2.7 environment) whereas I have anaconda 2. Dunno whether it makes a difference. Should be okay for python itself, but I'm not sure about the fortran extension modules.

Thanks, I will look into this in more detail.

Should work with latest conda builds on macOS. Alternatively pip install it from PyPI. The binary wheels have been processed with delocate to package the dynamically linked library dependencies with the wheel so the linker can find them.
