AttributeError: 'PlotLosses' object has no attribute 'set_max_epoch'

[KhondokerIslam]

Hi,

I am trying to use this library but the following error of no "set_max_epoch" attribute is showing. Thanks.

@KhondokerIslam Could you write the code and full error message?

I got this problem solved by reinstalling tensorflow and restarting my notebook

Great @loic-cgi !

Also, check out the next version 0.5.0 as there are new changes.
