No such layer: block1_conv1

[varrella]

when I change the value of "network" in default.cfg file, I got the following question, how to solve it?
It seems like the code works well when the value of "network" is "vgg16" or "vgg19", but when I modify the value of "network" to "densnet121" or "resnet152", the following problem will occur, how to solve it?

hey, did you get the solution to this?

@varrella @TUMFTM @fnobis I ran into the same error as mentioned above while changing the "network" to "densnet121" or "resnet152" . Help needed to resolve!
