Fundamental AttributeError when running PyMC that I cannot trace #125

Closed steveehlert closed 8 years ago

steveehlert commented 8 years ago

Hi all-

I have run into a very unusual issue with a PyMC run I am trying and I cannot explain why it is failing. Mainly, I want to do some MCMC sampling of a single sample of measurements against a custom scipy stats distribution, and for some reason the MCMC run is completely failing for reasons I cannot ascertain. The relevant code is below, but I don't see why it is giving me the failure of

AttributeError: 'builtin_function_or_method' object has no attribute 'dict'

This seems like a rather serious failure for something that is rather trivial conceptually. Any ideas where this came from and how to fix it? Thanks in advance!

I'd need to see the full error log to debug this. Its probably something to do with the scipy functions, as I have never seen this error before.

steveehlert commented 8 years ago

This is the full output I am seeing. I agree that the scipy functions are a likely culprit but I cannot seem to trace it to them.

How about this: return locals() instead of return locals.

steveehlert commented 8 years ago

Yup, that did it. I can't believe I forgot the () on the end of locals. Sorry to have wasted your time.

No problem. Happens to me all the time.
