I had updated my PyMC to 3.4.1.

yuliang0225 commented 6 years ago

I understand where is wrong. The code should be updated.

edoven commented 6 years ago

@yuliang0225 how did you solve? I'm having the same problem.

ryanxiang0306 commented 5 years ago

how to updated the code ?

BartKeulen commented 5 years ago

I cannot find the updated code either.

@yuliang0225 please add your fix.

bernha18 commented 5 years ago

same issue, somebody figured out?

ysgit commented 5 years ago

anyone who gets here and is trying to solve it, replace the code block with:

with model:
    trace = pm.sample(5000, init='advi', n_init=50000)
