Code modification problem

[ElliottZhen]

Hello author, may I ask if you ever encountered the error of DDP backpropagation when modifying the code on the basis of stark, such as the picture? I also modified on the basis of stark following your code style, and the error was located at loss.backward(), which could not be done with a single card? I'm very sorry to bother you. Looking forward to your reply.

Hello Wanzhen, I apologize for the inconvenience, but I haven't come across this issue previously, and as a result, I'm unable to provide any assistance. I'm sorry for any frustration this may cause.

Hello, I'm sorry for forgetting to reply you. Finally, I carefully read your code and solved the problem. I forgot to set the broadcast parameters of DDP.

Thank you for your open source, so that people with poor code ability like me can have reference resources, I wish you a smooth scientific research!
