ERROR with command: Command('bash scripts/gen_img.sh when running example case

[OlenaMaiakovska]

Dear authors,

When I run the example provided by executing samplot-ml:
snakemake -s samplot-ml-predict.smk -j 6 --use-conda --conda-frontend mamba

I get the following:

Your conda installation is not configured to use strict channel priorities. This is however crucial for having robust and correct environments (for details, see https://conda-forge.org/docs/user/tipsandtricks.html). Please consider to configure strict priorities by executing 'conda config --set channel_priority strict'.

Removing output files of failed job GenerateImages since they might be corrupted:
/home/olena/Applications/samplot-ml/outdir/img/HG03687
Shutting down, this might take some time.
Exiting because a job execution failed. Look above for error message

Do you have an idea what might be a reason and how can I solve it?
Thank you very much in advance!
Best wishes,
