gtburst hangs, not doing Likelihood Analysis

[nyctophile-aayu]

Hi Guys,

I have encountered a strange issue with the gtburst tool. Whenever I pick any GRB and start performing Likelihood Analysis, then after clicking on Run, it hangs. Also, generate an error. I have tried multiple re-installation of Fermitools but the issue is not resolving. If anybody have any idea, what is causing this error and how to fix this. Then please help me.

Regards,
Ayush

Please try
conda create -n fermicurrent -c conda-forge -c fermi fermitools numpy=1.20

I have tried that, it is giving me the same error as mentioned before:

(fermicurrent) ubuntu@ubuntu-HP-Z2-Tower-G9-Workstation-Desktop-PC:~ $ gtburst

Please suggest what could be the possible cause for it and how to resolve it. Also, I wish to know as it is an alternative, so why won't fermitools=2.2.0 work?
