How can explain the low of value for the accuracy for training (60%)

I tried many pre-trained model as Resnet-50, VGG-16, Inception V1 also algorithm from scratch but always I get the 60% in the accuracy in training and validation.

Why do you think I’m really very confused because I haven’t great experience in this topic?

@MootazMnasri

Could you share all models you tried creating and dataset steps with screenshots.
