assertion error assert x_t.shape == eps.shape

Hi I have trained the segmentation code on dataset ISIC. But when I am running sample I am getting the following error. I have used all the default parameters suggested and have not made any changes to the code except few print statement for debugging:

[W socket.cpp:663] [c10d] The client socket has failed to connect to [::ffff:127.0.1.1]:56131 (system error: 10049 - The requested address is not valid in its context.).

I also encountered the same problem. Have you resolved this bug now？
