I’m absolutely sure that my code has not changed so I was wondering if updates to NengoDL might be the cause.
On a theoretical level, what could be the cause of the error:
NotImplementedError: Cannot convert a symbolic Tensor (TensorGraph/while/iteration_0/meshgrid/Size:0) to a numpy array. This error may indicate that you’re trying to pass a Tensor to a NumPy call, which is not supported
Sorry about the code! I’ve been reorganising it and moved it to a new repository. Here are the NengoDL build function and OpBuilder for my learning rule and here is the OpBuilder for my neuron, which I register here.
Thanks again!
