Hi , i need help with my problem. Thanks .

Hello @MatějPROCHÁZKA 

I see

ValueError: could not convert string to float: '139,05'

Please correct me if I am wrong but I am guessing you used the Export Training Data tool when your Windows regional format was set to a Language that uses comma for decimal separator. This becomes a problem in the Training Deep Learning Models tool because this tool is expecting dots (periods) for commas.

It was a known problem in the Export Training Data tool because other Deep Learning tools don't support non-English languages yet. We have fixed this problem in the Export Training Data tool in v3.1. The tool will use dots for decimals.

For now to workaround this problem, you can either try replacing the commas with dots in the xml file or exporting out data with English regional settings.
