When I run “python train.py --dataroot ./datasets/UIBED --name chinamm_train --model cycle_gan” ，the error occured ：File "/root/TACL/train.py", line 60, in
objs.update(loss.data.item(), opt.batch_size)
AttributeError: 'NoneType' object has no attribute 'data'

Hello, have you solved this problem yet

When I run “python train.py --dataroot ./datasets/UIBED --name chinamm_train --model cycle_gan” ，the error occured ：File "/root/TACL/train.py", line 60, in objs.update(loss.data.item(), opt.batch_size) AttributeError: 'NoneType' object has no attribute 'data'

hey bro！The reason for this issue is that the model. optimize_marameters () on line 59 of train. py does not have a return value set in cycle_gan. You can obtain the loss by using loss=model. get_currentloss().

当我运行“python train.py --dataroot ./datasets/UIBED --name chinamm_train --model cycle_gan”时，错误发生：文件"/root/TACL/train.py"，第 60 行，在 objs.update(loss.data.item(), opt.batch_size)处，属性错误："NoneType"对象没有"data"属性。

嘿，兄弟！这个问题出现的原因是 train.py 文件第 59 行的 model.optimize_marameters()函数在 cycle_gan 中没有设置返回值。你可以通过使用 loss=model.get_currentloss()来获取损失值。

AttributeError: 'CycleGANModel' object has no attribute 'get_currentloss'

I can't figure it out
