I’m using ResNet18 for a classification task.
I tried using the pretrained model and training it from scratch: one thing that bothers me is that the time per epoch is more or less the same for both. On my GPU (GTX 1060), it takes roughly 19 minutes if I use the pretrained model, and around 23 minutes if I train it from scratch. For the pretrained model, I just re-initialize the first convolutional layer and the FC layer.
Is this expected?
