Keras: How to get layer index when already know layer name?

Question

I already knew the name of a layer of a model, now I want to know that layer's index. Is there any available function to do that? Thank you all.

Answer 1

Suppose your model is model and the layerName is name of the layer.

index = None
for idx, layer in enumerate(model.layers):
    if layer.name == layerName:
        index = idx
        break

Here index is the idx of required name.

Answer 2

The answer of Akhilesh as function:

def getLayerIndexByName(model, layername):
    for idx, layer in enumerate(model.layers):
        if layer.name == layername:
            return idx
