Is your code working in a terminal?
Are you using multiple workers in your DataLoader?
If so, could you add the “if-clause protection” as described here.

yes i am using num worker 2.

In that case, try to add the if-clause as described in the link I’ve posted.
There is a known issue on Windows machines using multiprocessing.

PS: You can add code snippets using three backticks ``` :wink:
This makes is easier to read the code and your code can be found by the search engine in this board.
