unable to train with more than one features. Error: mat1 and mat2 shapes cannot be multiplied (640x4 and 1x512) (model dim 512, batch size 128, no of features including target 4))

exogenous_vars = [] # I am adding feature columns to here, but sandbox.py works just when this list is empty

I'm having the same error. The input expected for the encoder is 1x512 dimension, and you're providing 640x4, this is what this error means. I don't know where to modify, did you find a solution?
