no callable exp method

How to debug such error?

TypeError: loop of ufunc does not support argument 0 of type ArrayBox which has no callable exp method

So far I encountered when starting some optimization parameters at zero (unchanged system) and sometimes when reducing the tunable parametric space.

More info:

AttributeError: 'ArrayBox' object has no attribute 'exp'

Sorry, it's best if you provide a minimum working example to reproduce the error, I don't really know how to fix right off the bat.

my apologies, I just sent the file to your email. The code is too long to conveniently paste here but it is just a build up on the examples that you have provided.

To my understanding, the error occurs when backend.exp() term in the Circle shape object is set to an integer zero. It appears that numpy.exp() and so is backend.exp() support explicitly inputs of float types.
