def forward(self, x):
if self.dowsample:
identity = self.downsample(x)
else:
identity = x
if need_downsampling == True:
self.downsample = do the downsampling stuff
else:
self.downsample = lambda x : x
def forward(self, x):
identity = self.downsample(x)
Is one of the above more computation or memory efficient than the other?
