backends

[Peter230655]

It seems, that backend='numpy' does not like zero initial guesses. Warnings like divide by zero or similar come up, but it continues to run.
backend='cython' does not report anything.
Is this to be expected, or is 'numpy' more 'sensitrive'?

Thanks!

@moorepants : I recall you mentioned something similar in one of your simulations, so I think, it is taken care of.
Not serious in any case as it continues to run.
