If I have the following model class for example:
class MyTestModel(nn.Module):
def __init__(self):
super(MyTestModel, self).__init__()
self.seq1 = nn.Sequential(
nn.Conv2d(3, 6, 3),
nn.MaxPool2d(2, 2),
nn.Conv2d(6, 16, 3),
nn.MaxPool2d(2, 2),
nn.Flatten(),
nn.Linear(myflattendinput(), 120), # how to automate this?
nn.ReLU(),
nn.Linear(120, 84),
nn.ReLU(),
nn.Linear(84, 2),
)
self.softmax = nn.Softmax(dim=1)
def forward(self, x):
x = self.seq1(x)
x = self.softmax(x)
return x
I know, normally you would let the data loader give a fixed size input to the model, thus having a fixed size for the input of the layer after nn.Flatten()
, however I was wondering if you could somehow compute this automatically?
CodePudding user response:
PyTorch (>=1.8) has LazyLinear which infers the input dimension.
