Train Deep Learning Model error

Hi. Geoprocesing show error when train Deep learning model.

Error:

Are you using a comma for the decimal separator?  If so, it appears not to be able to handle regionalized settings.

Thank a lot. I changed windows regional settings and now everything ok

Hello @MārisNitcis ,

Can you please elaborate on what regional settings were changed to fix the issue?

Thanks,

US regional settings. You must make sure that decimals are separated by a dot and not a comma.

I am just following this conversation. When I used the detect object using deep learning using self created training sample. I got the following result that is 100 percent incorrect. I am not sure there must be something wrong while creating the training sample. for building footprints, would there be only one class while labelling the sample under image classification tab?
