Re: PyTrilinos import error Mac OS

2017-08-29 Thread Seufzer, William J. (LARC-D307)

But wait… there’s more…

The afore mentioned conda install uses gmsh 2.15. There is a runtime error 
saying it wants a gmsh version > 2.5. I renamed gmsh in my environment and made 
sure I had a path into a > 2.5 version of the gmsh application on the Mac. I 
also had to do this on Linux. I had to rename (hide) since in trying to remove 
gmsh, conda also wanted to remove FiPy.

Then there was an error that I found described in:

https://github.com/usnistgov/fipy/issues/491

I went into mpi4pyCommWrapper.py, removed the recvobj form the allgather call 
and things seem to be OK.

That edit was done on both Mac and Linux.

Cheers,

Bill

Things should work on Mac OS X and Linux with:

conda create --name  --channel guyer --channel conda-forge fipy nomkl

Note, this does not work on Windows. On that platform, you should be able to do:

conda create --name  --channel guyer --channel conda-forge python 
numpy scipy matplotlib mayavi
source activate 
pip install fipy

There are presently no conda packages of any solver suite but scipy available 
for Windows.

OK, multiple things are messed up here and I'm not sure any of them are related 
to Apple possibly moving things. 

Things should work on Mac OS X and Linux with:

  conda create --name  --channel guyer --channel conda-forge fipy 
nomkl



Note, this does not work on Windows. On that platform, you should be able to do:

  conda create --name  --channel guyer --channel conda-forge python

Apple moved something between 10.11 and 10.12. It looks like my rebuild for 
10.12 from a few weeks ago broke 10.11. I'll have to figure out how to post 
both versions (and rebuild the 10.11 version at all).

PyTrilinos import error Mac OS

2017-08-22 Thread Seufzer, William J. (LARC-D307)

I get the following error on Mac OS 10.11.6 (Xcode 8.2.1 w/ command line tools 
installed). I used:

conda create --name pytril --channel guyer --channel condo-forge fipy

to create the environment (BTW, thanks for setting that up!!)

Father Google doesn’t seem to be of any help on this one.

The error:

I’m on a centrally managed Mac, so OS update is not an option. Xcode, gcc, and 
Conda install are under my control.

Thanks,

Bill
