cannot use BinaryScore

[rEstela]

Hi,
Thank you for this git! Is fantastic.

I'm having problems tying to use this for binary classification.

Can you show an example using it?

Thanks!

Thank you,
This is what I was looking for. Somehow didn't see these instructions O.o

I tried to use it on a simpler example (cat and dog binary classification) and it worked!

My problem now is when i have nested models...

I used the code:

score = BinaryScore(1.0)

replace2linear = ReplaceToLinear()

gradcam = Gradcam(model,
model_modifier=replace2linear,
clone=True)

cam = gradcam(score,
x_img,
penultimate_layer=-1)

But i got the following error:

ValueError: Graph disconnected: cannot obtain value for tensor KerasTensor(type_spec=TensorSpec(shape=(None, 141, 898, 1), dtype=tf.float32, name='conv2d_12_input'), name='conv2d_12_input', description="created by layer 'conv2d_12_input'") at layer "conv2d_12". The following previous layers were accessed without issue: []

If i do:

model2 = model2 = model.layers[1]

I have:

ValueError: output shape must be (batch_size, 1), but was (1, 64)

I face the same Graph disconnected error
