crnn acc =0 about crnn-pytorch

Hi, the images used in pre-trained model are generated by me and they all look very well. Just try to make more training data, it will work!

Thanks for the reply.
It really work after with more data and with more patient :)

I have another question :
While in training , all my input image size is (120,32) and in validation I saw there has a code
with "dataset.resizeNormalize(params.imgW,params.imgH)" . And in params, I set keep_ratio =True ,and imgW=120 , imgH=32. After several epochs training, my val acc comes to 0.96.

But when I put images which from CTPN model (different size of images) and send them to demo.py, the acc are terrible.

So, it means I have to put my training data with different size? (e.g: (300.32), (150,32), (500,32)..... )
But the code "dataset.resizeNormalize(params.imgW,params.imgH)" will resize and image will become distortion. What dataset did you make ?

Hi, the images from CTPN should look like your training data. If your training data is generated by yourself and looks very nice, while the images out from CTPN are more real, the net will do bad

So, you mean if I train with generated images and test with CTPN's crop image, then the result will be very bad.... ?
I have to train with self crop real images and test with TPN's crop images?
So the 3600 thousand dataset is useless?

Hello, I encountered the same problem, I used 6 million pieces of data for training. However, during verification, the predicted data is empty, and the previously generated data does not have this problem.
