[yt-users] from yt.analysis_modules.api import EnzoSimulation

[Matthew Turk]

Hi Shankar,

This is a worrisome error.  Please leave in the import in your script
and run it like this:

gdb python

At the gdb prompt, type "run my_script.py" where "my_script.py" is your script.

When it segfaults, type:

bt

And then send that here, to the list.

Best,

Matt
