This PR adds two tests for subtle issues related to this bug in
tt.switch
: pymc-devs/pytensor#270The tests are being added because these two bugs (#4389 and #4417) were rather surprising and difficult to debug. The tests fail before #4444 and pass afterwards.
I have included them in
test_model::TestValueGradFunction
because it seemed to be the most conceptually close block. For e.g.: https://github.com/pymc-devs/pymc3/blob/03d7af5b6dd5ad99ab2f3bd8ca7987a744dbef46/pymc3/tests/test_model.py#L338Closes #4417
