I am using the CPU mode execution. Did all the necessary changes recommended by you.

[GrayXu]

Sry, I haven't test codes on CPU enviroments, which is on my to-do list, but I'll check it soon...

[GrayXu]

Hi, after tests on my machine, removing all cuda() can use CPU mode normally. Can you tell your enviroments? I only tested them on torch==1.2.0 torchvision==0.2.0

[avinash-mishra]

Hi @GrayXu I did exactly same for CPU mode, but still I get following erros:

RuntimeError: output with shape [1, 256, 192] doesn't match the broadcast shape [3, 256, 192]

[GrayXu]

What's your pytorch version?
pip3 list | grep torch

---

Also I update codes to change running modes easily here

[avinash-mishra]

Thanks @GrayXu I installed exact version of torch and torchvision. And it is working fine.

Unfortunately, Cloth transfer results are not satisfactory. :(

[anantaarora]

Hi @GrayXu When I am clicking the radio button for selecting the cloth, it throws an error on submitting. We are saving them in static/img folder right?
