While reading your code, I saw this line of code, is it a comment to be taken into account? And what exactly is the problem? Thank

[qiaoguan]

do not need to take into account, just leave it alone

Hello, I have the same trouble, did anyone solve it?

[ShiinaMitsuki]

I solve it. just modify the script changeIndex.py at line 20 adn 21 as follow train_save_path = original_path + '/train_new' data_path = original_path + '/train' and run the script.

[qiaoguan]

yes, someone have issued this question before,just change the index of the label using changeIndex.py!

[lufei92]

@ShiinaMitsuki the code you modified has returned at line 17 and 18 in changeIndex.py, weather your mean is take them at line 21?

[ShiinaMitsuki]

@lufei92

here's the code of changeindex.py, I didnt see any return there.
