Error in py_call_impl(callable, dots$args, dots$keywords) : UnicodeEncodeError: 'ascii' codec can't encode character '\u03b5' in position 5: ordinal not in range(128)

Hi,

After the training I got this error:
Error in py_call_impl(callable, dots$args, dots$keywords) : UnicodeEncodeError: 'ascii' codec can't encode character '\u03b5' in position 5: ordinal not in range(128)

Do you how to fix this?

Many thanks.
