[yt-users] Re: yt dies/hangs with latest python/conda

And actually, if it *doesn't* provide you a traceback, you should be able to get one by running in pdb like: python -m pdb some_script_that_imports_yt.py and then entering 'c' to continue, and when you ctrl-c after it hangs it should tell you where it is.

Hi Romeel,

If you Ctrl-C out, does it tell you where it is in a traceback?

Hi, I seem to be unable to import yt after I had to upgrade my Anaconda to the latest version. First there was the dreaded cubehelix import error:

% python Python 3.9.7 (default, Sep 16 2021, 13:09:58) [GCC 7.5.0] :: Anaconda, Inc. on linux Type "help", "copyright", "credits" or "license" for more information.

...

...

...

import yt Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/rad/anaconda3/lib/python3.9/site-packages/yt/__init__.py", line 63, in <module> from yt.fields.api import \ File "/home/rad/anaconda3/lib/python3.9/site-packages/yt/fields/api.py", line 19, in <module> from . import angular_momentum File "/home/rad/anaconda3/lib/python3.9/site-packages/yt/fields/angular_momentum.py", line 26, in <module> from .vector_operations import \ File "/home/rad/anaconda3/lib/python3.9/site-packages/yt/fields/vector_operations.py", line 32, in <module> from yt.geometry.geometry_handler import \ File "/home/rad/anaconda3/lib/python3.9/site-packages/yt/geometry/geometry_handler.py", line 29, in <module> from yt.utilities.parallel_tools.parallel_analysis_interface import \ File "/home/rad/anaconda3/lib/python3.9/site-packages/yt/utilities/parallel_tools/parallel_analysis_interface.py", line 30, in <module> from yt.data_objects.image_array import ImageArray File "/home/rad/anaconda3/lib/python3.9/site-packages/yt/data_objects/image_array.py", line 18, in <module> from yt.visualization.image_writer import write_bitmap, write_image File "/home/rad/anaconda3/lib/python3.9/site-packages/yt/visualization/image_writer.py", line 26, in <module> from .color_maps import mcm File "/home/rad/anaconda3/lib/python3.9/site-packages/yt/visualization/color_maps.py", line 164, in <module> add_colormap("cubehelix", _cubehelix_data) File "/home/rad/anaconda3/lib/python3.9/site-packages/yt/visualization/color_maps.py", line 52, in add_colormap mcm.register_cmap(name, yt_colormaps[name]) File "/home/rad/anaconda3/lib/python3.9/site-packages/matplotlib/cm.py", line 245, in register_cmap raise ValueError(msg) ValueError: Trying to re-register the builtin cmap 'cubehelix'.

I tried a conda update yt, also installing from pip, same result.

So I pulled the latest development version and installed it. This doesn't give the cubehelix error, but it simply hangs with no output whenever I try to import (or run) yt.

Any suggestions would be appreciated, thanks. _______________________________________________ yt-users mailing list -- yt-users@python.org To unsubscribe send an email to yt-users-leave@python.org https://mail.python.org/mailman3/lists/yt-users.python.org/ Member address: matthewturk@gmail.com
