Hello,

Whenever I try to open ModelView (the number of Thread is 1), it generates an error message:

Code: Select all

      mview()
    execute("mview()")

At first, I made sure that spicy was installed in the computer but still the error occurred. Would you please help me to use ModelView?

Thank you for your help in advance.

This is fixed in the development version, but in brief: NEURON isn't recognizing your version of scipy and so it can't tell if it's new enough to use certain features, and so it's crashing.

A work around is to edit the file /Applications/NEURON-7.4/nrn/lib/python/neuron/rxd/options.py using your favorite text editor, and replace the line

scipy_version = [int(v) for v in scipy.__version__.split('.')]

with scipy_version = [1, 0, 0]


Sorry about that.

I believe that bug was probably fixed Feb 5, 2016

I recommend uninstalling NEURON-7.4 by dragging to the trash and installing
