Keras verbose training progress bar writing a new line on each batch issue

Question

running a Dense feed-forward neural net in Keras. there are class_weights for two outputs, and sample_weights for a third output. fore some reason it prints the progress ver

Answer 1

This seems to be a consistent problem with Keras. I tried to find the lines

sys.stdout.write('\b' * prev_total_width)

sys.stdout.write('\r')

at the Keras/utils/generic_utils.py file and they are (as of the current version) at 258 and 259 accordingly. I commented like 258 but this seems not to resolve the issue. I did manage to make the progress bar work by commenting the line:

line 303: sys.stdout.write(info)

It seems as if the info makes the bar too long for the terminal and so it breaks to a new line.

So I finally resolved the issue. It seems like it was rather simple at the end....

Just make the terminal wider...
