Syntax and logical errors

[sazani]

First of all thanks for shring your great works. However, I found some syntax and logical errors for all three transformers. One of them related to CLTV,
for cnn, transformer in self.layers:
x = cnn(x)
x = norm(x)
x = transformer(x)

### It should be:

for cnn, norm, transformer in self.layers:
x = cnn(x)
x = norm(x)
x = transformer(x)
