How to extract the tensor element from tuple?

1

I have a prior which is multivariate gaussian and a tensor zs.
self.prior.log_prob(zs[-1])

the above line of code is throwing the folowing error:

AttributeError: 'tuple' object has no attribute 'log_prob'

Please help

Based on the error message self.prior seems to be a tuple, so you would have to unwarp or index it to access the distribution, which defines the log_prob method.
