Problems with more traffic sign classes, help please!!

[tony9378]

Hello,
I met "train loss : nan, validation loss ：nan“ since more traffic sign classed been added by following steps.

In file creat_pickle.py

sign_name = fields[1]
if sign_name != 'pedestrainCrossing' and sign_name != 'signalAhead' and sign_name != 'stop':
continue
sign_class = sign_map[sign_name]
class_list.append(sign_class)

It seems that something wrong with your data.
you should use data_prep.py to create data_prep_400x260.p ,It almost 514MB
