I am fitting a sample using prior distribution nd getting following error:

Seems like you have an issue with your installation of Aesara

Try a function with a dot and its gradient

I didnt get you. You meant to calculate gradient of a function output.

I mean that the Aesara function you tried was too simple. I think you have an issue with caching/installation and you would get a similar error if you tried to evaluate an Aesara function that has a dot operation and/or possibly its gradient wrt to one of the inputs as well.

Can you replicate your PyMC model in google colab? https://colab.research.google.com/

And if so, can you share the colab afterwards?

Thanks for the suggestion . I need to see how can do it. Colab is blocked in my organization but will see how can i share it by some other means.
