About _epoch_train and _epoch_val

[fireholder]

When i was traning, I've met a problem that the progress came to a standstill. And I've found that it was the function _epoch_train and _epoch_val stopped it, which raises NotImplementedError. I wonder why and how to fix it.

[Ike-yang]

hi, bro, I am trying to run the trainer.py, but I don't know about the argument "--load_model_path", there is nothing in the current folder, I am sure what kind of pretrain model need to load here, any advise?

[fireholder]

I think '--load_model_path' is only used when 'pretrained', but the log.txt shows error when not loading model files.

[Ike-yang]

Exactly, I got something in the logs.txt file like this : Vocab Size:1173 [Load Model Failed] [Errno 2] No such file or directory: '' [Load Model Failed] [Errno 21] Is a directory: '.' [Load MLC Failed [Errno 21] Is a directory: '.'!] [Load Co-attention Failed [Errno 21] Is a directory: '.'!] [Load Sentence model Failed [Errno 21] Is a directory: '.'!] [Load Word model Failed [Errno 21] Is a directory: '.'!] Namespace(attention_version='v4', batch_size=16, caption_json='./data/new_data/.......

I thought program just stop here because of the error message. So, I could just ignore the message, and keep training? Are there other places need to be modified?

[fireholder]

I find that it's not stopped, it's just not printed.

[Ike-yang]

Yeah, I leave it to run all night, but I found val_loss is always 0 in logs.txt, there must something wrong and need to be modified

[fireholder]

Because in '_epoch_val' all val loss is set to 0, you can try uncomenting the code in '_epoch_val'. But I find my train loss very large, is it the same to you? By the way, have you tried the tester

[Ike-yang]

Yes, extremely large train loss. Haven't tried the tester yet

[Ike-yang]

I have tried tester.py, not working, someplace need to convert tensor.cpu(), have you run tester.py completely?

[fireholder]

Yes, just convert to tensor.cpu() as the error suggested.

[fireholder]

However , My test results are all the Same. All my predicted captions are the same

When I run python tester.py

Did u guys met the problem like"

Hi @fireholder! Did you eventually give up trying to solve the issue? were all the predicted captions always identical?

[yangyan22]

My train loss is also very large. And all my predicted captions are the same: "No acute cardiopulmonary abnormality", could anyone do me a favor? Thx! Is it because of Python2 and Python3, since I used python3.

[AnkitMalviya]

Yes, extremely large train loss. Haven't tried the tester yet

Hi, you were able to decrease the loss. I am also facing the same issue.

I guess train loss is large, because author uses MSELoss for predicting tags. If he has 156 different tags, then the exponent ~ (156-0)^2 = 24336. That is why so big loss

You can change it L1Loss or decrease lambda argument for tags loss (if you find it reasonable).

[Hareem1997]

In debugger.py and tester.py file of the given project. I'm facing an error at 3rd last line in the following given section of code. ` tag_loss += self.args.lambda_tag * batch_tag_loss.data stop_loss += self.args.lambda_stop * batch_stop_loss.data word_loss += self.args.lambda_word * batch_word_loss.data loss += batch_loss.data

return tag_loss, stop_loss, word_loss, loss`

Error is : File "D:/Hareem/Auto_report/debugger.py", line 61, in train train_tag_loss, train_stop_loss, train_word_loss, train_loss = self._epoch_train() File "D:/Hareem/Auto_report/debugger.py", line 424, in _epoch_train word_loss += self.args.lambda_word * batch_word_loss.data AttributeError: 'int' object has no attribute 'data'

Is there anybody who solve the problem predicting captions all the same?
