Is it possible to get the information regarding the fused activation functions used from the .tflite file?
I know that could do the job of visualizing it, but I'm looking for some functions which could print the information.

Thanks in advance.

I specifically wanted to that, let's take an example, for a fully connected layer with relu as activation function, I would like to extract the info which states that relu is the activation function used here.

At first, I thought a string search around the tensor layer might do the trick, but that wouldn't work in all cases, esp when the last layer is an FCNN with relu as activation function(here, the tensor name would be changed to Identity)

int8ops (12).tflite

The activation status is stored at the operator options like the below link in the flatbuffer file

You can retrieve it from the operator table like the below point:
