Hi all,
I’m trying to run a super-resolution by implementing EDRS following the super-resolution lesson 2018/2019.
When I run learn.summary().
I get this error:
TypeError Traceback (most recent call last)
Cell In[9], line 1

211 xb = self.dls.train.one_batch()[:getattr(self.dls.train, “n_inp”, 1)]

213 res += f"Optimizer used: {self.opt_func}\nLoss function: {self.loss_func}\n\n"
214 if self.opt is not None:

627 def has_children(m):
→ 628 try: next(m.children())
629 except StopIteration: return False
630 return True
TypeError: children() missing 1 required positional argument: ‘self’
I’m wondering if it’s say I have to flatten the model. eg. the flatten layer is missing
Here my layers classes:
class ResSeq(nn.Module):
def init(self, layers, resScale =1.0):
super().init()
self.resScale = resScale
self.m =nn.Sequential(*layers)
def forward(self, x):
return x+self.m(x) * self.resScale
class edrs8(nn.Module):
def init(self,nf,scale):
super.init()
features = [conv(imgchnl,flt)] #starting convolution
for i in range(nResBlock):
features.append([resBlock(flt)]) #ResBlock
features +=[conv(nf,nf),pixShuffleBlock(nf,nf,scale),
nn.BatchNorm2d(flt),
conv(flt,4)] #exit of ResBlock and adding pixel shuffle
self.features = nn.Sequential(*features)
Thanks for the help
