Flair: crash on startup

Versions

Please provide the used software versions.

FLUKA: 4.5.1
Flair: 3.4-5.2
Operating system: ubuntu 24.04

Description

Dear experts,

When I start flair (on terminal or by clicking on icon), it crashes immediately, with the following message: Segmentation fault (core dumped). I have installed it with both methods, deb. packages or from repository.

I suspect a problem with python and its double installation on my work station with the Anaconda distribution.

Is there a way to specify that flair should use the regular python libraries?

Thanks in advance,

Jean-Emmanuel

Input files

Please upload all relevant files. (FLUKA input file, Flair project file, user routines, and data files)

Dear @jegroetz

if you are using a specifically created conda environment, try deactivating it with

conda deactivate

and then try to run flair from that same terminal.

If Anaconda installed packages right in your standard environment (not sure if this is still possible, but a bad idea anyway) try creating an empty environment, activate it and run flair from there.

Lastly, you could try to reinstall flair, but this time making sure you run the installation from the same conda environment you usually use.

Best regards
Roman

Thank you Roman for your suggestion, now flair works by disabling conda, both from terminal and icon in the applications environment.

Best regards,

Jean-Emmanuel
