Hi Nathan, Yahoo! doing the conda install instead of pip has fixed it! For completion, though, here are the answers to the other two questions: Yes, it all runs nicely (until scipy is needed) if I don't have scipy installed. If I start python and type import scipy.optimize I get a Segmentation fault --when I used the pip install version. with conda install, import scipy.optimize seems to work fine. Thanks!!!

Hi Nathan,
I am not sure how to get a core dump or how to make gdb give me useful things. But maybe this will help...
By running my code via a command line, I find that import h5py import scipy import yt from yt.analysis_modules.cosmological_observation.api import LightRay
all are fine. But,
from yt.analysis.modules.absorption_spectrum.api import AbsorptionSpectrum from yt.analysis.modules.absorption_spectrum.api import generate_total_fit
And both of these succeed when scipy isn't installed?
What happens if you do:
import scipy.optimize
Also you're using the conda-based python that the latest version of the install script builds, right? Maybe you should try the conda binary builds instead:
$ pip uninstall scipy $ conda install scipy
both give me a Segmentation fault and kick me out of python
I can keep trying to figure out how to have gdb give me something useful, but does this give any clues in the meantime?
Thanks, Stephanie

Hi Stephanie,
It's very hard to say what's going wrong without more information.
Can you get a core dump or run python under gdb to get a stack trace at the place where the segmentation fault happens?
Can you run this on your laptop? If so, do you get a segmentation fault there?

Hi all,
I have the yt-conda installation of yt. I am trying to create an absorption spectrum, so need the command "generate_total_fit".
yt told me I needed scipy for this to work. yt does not have scipy. So I typed:
pip install scipy
scipy was installed.
However, then my submission script no longer worked at all and I was given the error:
/var/spool/torque/mom_priv/jobs/50052.mies.stanford.edu.SC: line 26: 3750 Segmentation fault python HI_absorbers.py
When I pip uninstall scipy, my code runs again! The only commands in my script are source /home/stonnes/yt-conda/bin/activate python HI_absorbers.py
Can anyone help me out with this?
Thanks! Stephanie
