Error due to 'Segmentation Fault' on Linux
Hey, I keep running into the issue of "Segmentation Fault". I am working on Linux and tried reinstalling the environment/phy. The following error messages appear:

Segmentation fault
Incase that helps somehow: when using another environment (without the respective libaries), Phy is opening, but showing blank (white) ClusterView and SimilarityView; other panels are black except of TraceView. Even the test-dataset provided doesn't work with both scenarios (environments).
Thank you for your help, Paul
As mentioned in #1231, I installed phy via environment.yml and ran into the following problem with the imp libary. Did you find a solution yet?
(phy2) paul@spikesorter:~/Downloads/phy-data-master/template$ phy template-gui params.py --debug
Traceback (most recent call last):
File "/home/paul/miniconda3/envs/phy2/bin/phy", line 5, in
Found a workaround using the base version environment and the command in #1143. Please inform me about any other solution if possible.
What exactly was your workaround? I've had the same segfault issue on Ubuntu 22.04.
I just tried to run env QTWEBENGINE_CHROMIUM_FLAGS="--single-process" phy template-gui params.py
as recommended in #1143 in the regular phy2 environment, but still got the same error. I likely missed something, any help is greatly appreciated.
@fbartsch try the preexisting base environment, that somehow worked for me
@paulweger still not working for me, but thanks for confirming - I'll keep looking.
You should install with the environment yaml instead. But when you download it you need to edit it and limit it to python=3.11. You should never install in base. It can break your conda install. @fbartsch , @paulweger.
I have a PR open to fix the imp issue, but I'm waiting for review and merge.
@zm711 Ha, that (and a quick reboot after reinstalling using the yaml) did it! Thanks so much!
