Thank you sir, it solved the problem, I’m trying another thing here, and I failed to fine-tune the model. It’s my first time doing that. It will take ages, if I’m going to run the model from the begining espacially it’s not the dataset that I will work on, I just want to test if it works properly. I will apperciate if you take a look on this one : Fine Tuning a Resnet Model . Thank you.
