Hi luisroque,
thanks for your reply.
I actually added the shape arguments because I was getting this error:
TypeError: For compute_test_value, one input test value does not have the requested type.
The error when converting the test value to that variable type:
Wrong number of dimensions: expected 0, got 1 with shape (1,).
Concerning using Metropolis, I’m actually using it for a particular reason, do you think it is what is causing the problem?
