ERROR IN PROCESS mountainsort.compute_templates

[alfonsogravante]

Dear,
I recently started using mountainlab / mountainsort. I completed the installation, prepared my data and started the process, as described in the guide (old / doc / installation.md).
right now I'm in front of a problem that I can't solve. specifically:

---

I installed mountain sort on linux mint 19.2 with a virtual machine.

I'm not an expert and I don't know how to proceed.
do you have any ideas?

thank you my friends!!
