[Python] Issue to install pyarrow and pandas together in a conda environment

[Mathias5]

Describe the bug, including details regarding any error messages, version, and platform.

Hi,
since a few days when I create a conda environment with pyarrow and pandas, I get a segmentation fault when loading pandas.
To replicate:
conda create -n test python pyarrow pandas
conda activate test
python
import pandas

This leads to a segmentation fault.

Component(s)

Python

Can you show the output of conda list? Do you see any traceback or error message besides "segmentation fault"?

This is probably a conda packaging issue.

Hi. I believe the issue is related to new release of snappy 1.2.0
Similar issue is solved (for me) with snappy 1.1
I get same bug (segmentation fault). specifically:

File "/homes/.../.conda/envs/.../lib/python3.10/site-packages/pyarrow/init.py", line 65, in
import pyarrow.lib as _lib
ImportError: /homes/.../.conda/envs/.../lib/python3.10/site-packages/pyarrow/../../.././liborc.so: undefined symbol: _ZN6snappy11RawCompressEPKcmPcPm

If that was the issue, that should be solved now when recreating a fresh environment, see #41058

But, that issue should only have occurred since yesterday, and not for a "few days" (and it's also not a segmentation fault)

Hi,
Indeed I think it started to happen yesterday and not "a few days ago" as I initially said.
And it did cause segmentation fault in my python env.
It seems like it has been resolved now, thanks for the update.

The issue has been resolved, see #41058
