WebAug 29, 2024 · Well, with conv layers in pyTorch, you don't need to specify the input size except the number of channels/depth. However, you need to specify it for fully connected layers. So, when defining the input dimension of the first linear layer, you have to know what is the size of the images you feed. WebEach machine learning model should be trained by constant input image shape, the bigger shape the more information that the model can extract but it also needs a heavier model. … change font of icons
