error when the output_size isn't 1

[mhdabbasi]

I get error when the output_size isn't equal to 1 in forecasting code.
for example when the output_size is 10. I get this error :

return F.linear(input, self.weight, self.bias)
RuntimeError: mat1 and mat2 shapes cannot be multiplied (16x65 and 74x10)

Set the environment variable HYDRA_FULL_ERROR=1 for a complete stack trace.
