Computational Cost in Spiking Neural Network

Hello Brian Community,
I am simulating a simple 2-layer spiking neural network to classify naturalistic textures. I would like to ask if there is any rule or tool that I can use to calculate the FLOPs of my network?
worth mentioning that I am using brian2 simulator.
I appreciate your help.
