4 layer SNN using Nengo Core (2.80)

Hi Eric,

Thank you for quickly reviewing the post and the helpful guidance to further develop the SNN network. Yes, this one is from Single-Layer MNIST example. My goal is to build a 4 layer network (if possible in the NEF encoder based approach) for inference using the weights from an identical network (I have the weights). Training is not necessary for the one I am trying to build, but if the weights can be further optimized/learned, that will help!

If you can take a look at the code and suggest some improvements, that would be great!
You can call me Krishna.
Thank you!
Best Regards,
