Robert - any suggestions?

Hello,
I just did a fresh install of HNN on a macOS High Sierra.
When I tried to run the Simulating Rhythmic Proximal Inputs: Alpha Only
tutorial, the simulation instantly aborts and the terminal gives off the
following message:
`
Starting simulation. . . mpiexec noticed that the job aborted, but has no
info as to the process
that caused that situation.
WARN: could not read simulation outputs:
dict_values(['/Users/ashish/hnn/data/default/dpl.txt',
'/Users/ashish/hnn/data/default/rawspec.npz',
'/Users/ashish/hnn/data/default/spk.txt',
'/Users/ashish/hnn/data/default/param.txt'])
`
Not really informative as the error message doesn't know what exactly
caused the simulation to abort. Please let me know if you need any other
info to solve this. Thank you!

Do any of the tutorials work? If not, does NEURON load successfully? e.g. if you do
and then in python try "import neuron", does it succeed or fail? If it fails, try:
and then see if the previous test now succeeds or fails. |
One other thing to check: Does typing "python" load Python 2 or Python 3? (It should say in the banner.) |
After some digging, it seems that the newer versions of MacOS doesn't include openMPI, which is required to run HNN simulations I assume? After installing I am now seeing the following: Starting simulation. . . does this help? |
hi @ramcdougal
|
Just to confirm: Are you using Anaconda Python? I would have expected doing the conda install of mpi4py to install openmpi, but you can try removing the openmpi you installed and explicitly doing the conda install of openmpi:
(sudo is assuming you've installed for all users; if it's a local install, do not use "sudo"). |
I did the conda install for mpi4py and openmpi, loaded the tutorial parameters, clicked run simulation and now i'm getting the following: Starting simulation. . . [iMac-Pro.radiology.ucsf.edu:46680] PMIX ERROR: UNPACK-PAST-END in file unpack.c at line 122 [iMac-Pro.radiology.ucsf.edu:46683] PMIX ERROR: UNPACK-PAST-END in file unpack.c at line 122 [iMac-Pro.radiology.ucsf.edu:46685] PMIX ERROR: UNPACK-PAST-END in file unpack.c at line 122 [iMac-Pro.radiology.ucsf.edu:46688] PMIX ERROR: UNPACK-PAST-END in file unpack.c at line 122 [iMac-Pro.radiology.ucsf.edu:46690] PMIX ERROR: UNPACK-PAST-END in file unpack.c at line 122 [iMac-Pro.radiology.ucsf.edu:46691] PMIX ERROR: UNPACK-PAST-END in file unpack.c at line 122 |
To help diagnose. results of the following tests may be useful. Run tests in a terminal.

@vogdb thanks for the instructions above. This error can come about in at least a couple of ways. Even if
I don't know where the 10 comes from. Perhaps @ramcdougal has some insight from the NEURON macOS installer? |
I'm glad @vogdb and @blakecaldwell provided some easy solutions! To be honest, I don't have access to the Mac machine I did this install on anymore, it wasn't my Mac :( So I can't provide more info on my end, apologies. If we can confirm thatextra 10 in Thanks again for all the help and debugging! Really grateful :) |
