Hello @Eric, with respect to my 1st question above, I did some related experiments with a passthrough node, which was supposed to aid in two consecutive transforms. Unfortunately, NengoLoihi throws error that merging transforms work only with Dense transforms and it suggested to set remove_passthrough=False. So this clarifies my first doubt to check programmatically… that passthrough nodes are set (True) to be removed. Although, upon setting remove_passthrough=False, I got the same error
BuildError: Conv2D transforms not supported for off-chip to on-chip connections where `pre` is not a Neurons object.
as mentioned here. But I was able to circumvent it.
With respect to my 2nd question above, please let me your points.
