I’m working on a project and I need the output of a truncated ResNet. Taking ResNet18 as an example, if I do the following changes
import torch import torch.nn as nn import torchvision.models as models resnet = models.resnet18(pretrained=False) resnet.avgpool = nn.Identity() resnet.fc = nn.Identity()
The output gets flattened and I don’t know why. The curious thing is that if I forward a (16, 3, 256, 256) tensor through it, I get an output of size (16, 32768), while if I manually forward the input layer by layer, I get the expected output (16, 512, 8, 8). It seems like a bug, but I’m not sure. Can anyone take a look into it?
