Hi everyone! In my CNN structure defined in the the __init__ method I have different Linear layers which are fed with feature maps that are obtained from Conv2d layers. By leaving the network structure as-is, my network is dependent on the input image size. Is there a way to comvert the linear layers to Conv2d and obtain the same results?
This is the code:
...
self.smooth1 = nn.Conv2d(512, 256, kernel_size=3, stride=1, padding=1)
self.smooth2 = nn.Conv2d(768, 256, kernel_size=3, stride=1, padding=1)
self.smooth3 = nn.Conv2d(1024, 256, kernel_size=3, stride=1, padding=1)

# Fully Connected Layers
self.fc5 = nn.Linear(256*25*25, num_classes)
self.fc4 = nn.Linear(256*50*50, num_classes)
self.fc3 = nn.Linear(256*100*100, num_classes)
self.fc2 = nn.Linear(256*200*200, num_classes)

In the Linear layers 25, 50, 100 and 200 depend on the input image size. Is there a way to make the “independent”?
