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
