again thanks for reporting! can you send me the config files you have in the project_folder/configs directory as a zip and I will take a look?

Thanks Sara - it's odd, I could not reproduce this error, with my configs or yours, but I inserted a couple of rows that should correct for it if it occurs.

Can you try with simba version 2.0.9 using pip install simba-uw-tf-dev --upgrade --no-deps and see how it runs on your end?

Hi @sronilsson,

Thank you ! I used simba 2.0.9 and the training job was completed successfully.
