The error when I try to change the batch_size

[StephenChen625]

@whywhs First of all, thank you very much for providing the source code. The training process was too slow when I run with the default settings(about 20 minutes/epoch). I tried to add the num_workers, but there's not much improvement.

When I wanted to change the batch_size to 2 or 4, the following error occurred:

Could you please help me solve the problem? Thanks a lot.

Sure, I'm glad to answer your question. I'm sorry for that I didn't add batch_size to this project. So, if you add batch_size, the error will occur.

[StephenChen625]

Thanks for your answer. Okay. I'm going to run a weekend under the setting, and see the results. By the way, how many epochs are needed before convergence? I have run 14 epochs, but the sacc is still 0.

Here is part of my log info: epoch is 14, the whole loss is 10.573622 wer is 0.50119 sacc is 0.00000 the best is 0.479045

[whywhs]

yes, I have also noticed this problem. I've been ran about 120 epochs, and the sacc is always 0. I'm also confused and I don't know what's wrong.
Recently, I've been updating my program and try to solve this bug. Meanwhile, I suggest you try to test accuracy with Densenet_testway.py

[StephenChen625]

Looking forward to the updates. Ok, I'll try the Densenet_testway.py. Thanks again.

Thanks so much for updating your code. Now I've successfully trained on batch.

Here is some problems when I tried to train:

1. Error: ModuleNotFoundError: No module named 'Resnet101' Solution: Comment the line 16 in Train.py "# from Resnet101 import resnet101"

2. Error:FileNotFoundError: [Errno 2] No such file or directory: 'densenet121-a639ec97.pth' Solution: I downloaded the model by hand through the urls in Densenet_torchvision.py "'https://download.pytorch.org/models/densenet121-a639ec97.pth'". I don't know why it didn't download automatically.

By the way, I found a new paper about HMER, which claims to have a very good result. I'm new to deep learning, so I'm unable to realize it. But I hope it can help you with your research.

Hi, Thanks for you to remind me about the BUG from my code. If you want to download the pretrain Densenet, you can use this https://download.pytorch.org/models/densenet121-a639ec97.pth Finally, I will read this paper and see what I can do

[StephenChen625]

Thanks. I'll follow your updates.
