__getitem__ function cannot be invoked #3

Closed turinglife closed 4 years ago

turinglife commented 4 years ago

my environment:

  1. Ubuntu
  2. Pytorch 0.4.1
  3. Python 3.5

Does anyone encounter this problem? Thanks.

turinglife commented 4 years ago
  1. init function in dataset_nocs.py can be invoked successfully.
  2. the code line "optimizer.zero_grad()" in the train.py can be performed successfully.
  3. When performing the line of "for i, data in enumerate(dataloader, 0):" in the train.py, the getitem function cannot be called and then the program has been in halt status(like suspending, it's not crash). I printed the length of dataloader, which is 5000.

Thanks!

Hi, it's probably because the "try-except" code hides the bugs in your dataloader. This is why it seems like your program is halted. One method is to first remove the "try-except" code in Line 434 and Line 457 of the dataset/dataset_nocs.py. Then you can see the bugs. Another easier way is to add KeyboardInterrupt into the except situations, which is how I do to debug the dataloader.

Hello, I met the same problem with you. The program has been in halt status at dataloader 5000. Could you pls tell me how solve the problem?

Many thank!
