RuntimeError: DataLoader worker (pid(s) 17016, 18312) exited unexpectedly
This error is usually caused by one or more worker processes in the DataLoader crashing and can be due to many different issues, such as insufficient memory, wrong file paths, or other system issues.
Here are some workarounds:
1. Reduce batch_size: Reducing batch_size may reduce memory usage, thereby reducing the possibility of DataLoader process crash.
2. Increase num_workers: Increasing num_workers may increase the parallelism of DataLoader, thereby reducing the possibility of DataLoader process crash. However, be careful not to increase too much, or it may cause excessive system resource consumption.
3. Check the data file path and format: Make sure the file path is correct and the data format is consistent with the format specified in the code.
4. Check system resources: Make sure the system resources are sufficient, such as memory, disk space, etc.
5. Use the try-except statement: Use the try-except statement in the training code to catch errors and process them when the DataLoader process crashes.
If the above does not resolve the issue, you can try restarting your computer or training with a different environment or computer.
