Kohya_ss Lora not working


I have a problem while trying to create a lora of character with Kohya_ss gui for SD automatic1111 . I think I did everything acording to the setup, but when I try to generate lora everything looks like working, but the final file only has 9Mb instead of the cca 145Mb that it should have. Could anybody help me with this problem?

Thanks in advice.
