Thanks. It worked.
But one more thing to mention, when I try to import pre-trained model to Pytorch from Lasange, something weird has happened. Let me describe a little about my problem. I would like to do fine-tuning on my dataset after importing. But Importing does not have any effective result. During the training, the accuracy metric of the system is random, and it seems that there are not any traces of learning from my data (with transfer learning). However, when I start to learn the network from a random state without any transfer learning, the performance metric changes and shows something is learned during the training. Do you have any idea what is the problem?
