It seems like broadcasting information gets lost when applying `pm.make_shared_replacements`, leading to problems with the metropolis sampler. Potentially related issues below: - pymc-devs#1083 - pymc-devs#1304 - pymc-devs#1983 This fix was previously suggested in the following issue: - pymc-devs#3337 It could be that further adaptations are necessary as indicated in the issue.

The original fix was merged into master after the Aesara rename and this PR cherry-picks it onto the v3 branch.
