[Bug report] test failures on s390x/i686/aarch64/ppc64le

[sanjayankur31]

Describe the bug

While building NetPyNE for Fedora, we're running examples as tests on all the architectures Fedora supports. Of these, on s390x, i686, ppc64le, and aarch64, some of the examples fail.

https://fedoraproject.org/wiki/Architectures

All examples run fine on x86_64.

Reproducing the bug
Run examples on different architectures after building netpyne from source. The build spec can be seen here:

https://src.fedoraproject.org/rpms/python-netpyne/blob/rawhide/f/python-netpyne.spec

Steps to reproduce the behavior:

1. on i686, s390x, ppc64le: doc/source/code/tut2.py fails. On aarch64, doc/source/tut6.py fails

These are the first examples fail, and they cause the build to fail. There may be more tests failing, I'm still checking builds.

Build logs for all of these attached:

netpyne-aarch64-log.txt
netpyne-i686-log.txt
netpyne-ppc64le-log.txt
netpyne-s390x-log.txt

Here's the test build (but it'll be deleted in some time): https://koji.fedoraproject.org/koji/taskinfo?taskID=82980719

Expected behavior

They should ideally run fine

System information

• OS and version: [e.g. iOS 10.14.6] Fedora rawhide (37)
• NetPyNE version: [e.g. 0.9.5 (see CHANGES.md for version)] 1.0.0.2
• NEURON version: [e.g. 7.6.4 (run nrniv --version in terminal for version)] 7.8.2
• Python version: [e.g. 3.7.0 (run python --version in terminal for version)] 3.10

Additional context

NEURON builds fine on these arches, but I've not really run any tests to check if it's the underlying cause of these errors.
