EfficientNet GradCAM doesn't work

[vesalucsf]

Could you advice on how to plot GradCAM for EfficientNet. The current strategy you mentioned on the tutorials won't work, specially my last activation is a sigmoid.

Thank you for letting us known!

I will examine the cause of the problem.
Because I want to understand the error and the situation where you find the problem, could you please submit the code snippet that reproduce the problem?

Thanks!

Hi, @vesalucsf , I'm sorry for the late reply.
I've tried to reproduce the problem, but couldn't it.

specially my last activation is a sigmoid.

Did you replace the sigmoid function to a linear function?
If not, please try it such as below:

model.layers[-1].activation = tf.keras.activations.linear

I'll close this issue.
But when the problem is NOT resolved or you have any question, please feel free to reopen this issue.

Thanks!
