3 years ago Hello @Ronald-Kray Could you able to solve this problem?
I also got the same error almost.
Could you please help me with this?
Previously I also got error in dataset.py line [261]. Since I have string in my train.txt I have the line in the following way: truth[data[0]].append([int(float(j)) for j in i.split(',')])
Could you also clarify me how you prepared your dataset and where did you place the file?
Please help me With this @Tianxiaomo
