Strange NameError Issue #130

Closed steveehlert closed 6 years ago

steveehlert commented 8 years ago

Hi all-

I am running into a very strange error whose origin I cannot ascertain. I am not sure what is causing it, but here is the error output. Are there any reasons I would expect something like this? I have a good amount of experience running the pymc library and don't know why this would happen now. 

Tuning at iteration 1000
Metropolis_massindex tuning:
    value: 1.99308772654
    acceptance rate: 0.035

You appear to have quite an old version of PyMC. Can you try updating to the most recent release, or better yet, install from master:

pip install -U git+https://github.com/pymc-devs/pymc.git
