mcmc_sampler not visible from do_samplers about dowhy HOT 8 CLOSED

I tried this and am unable to reproduce--seems to work on my setup. Can you share your python version/system details?

from dowhy.

Python version 3.6.3 :: Anaconda custom (64-bit)
OS Ubuntu 16.04

if there is more that you need (dependencies on system libs? versions of some other programs?) I'm glad to provide that information too

can't recreate on my ubuntu 18.04 setup. can you make sure you're up to date with master?

Thanks for getting back to me. I still get the error but looking closer at the error message I saw that pymc3 is missing.
After installing pymc3 I got a key error about blas. blas is installed. There was also a missing environment variable, which I set and I got a lot of complaints about theano not having a compile module. So I will have a look at the dependencies again to find the reason before I continue to answer here. And maybe I'll upgrade to 18.04 first.

EDIT: running pip install -r requirements.txt says that all requirements are met.
EDIT 2: running the do_sampler_demo notebook and adding a block at the end the mcmc_sampler IS found. So something is weird in my setup and you will definitely not be able to solve this.
import dowhy.do_samplers as do_samplers
do_samplers.get_class_object("mcmc_sampler")
OUT[9]: dowhy.do_samplers.mcmc_sampler.McmcSampler
EDIT 3: when I start ipython in the dowhy troot directory, the object exists. So it seems like something is missing in setup.py and not everything is visible when I'm working in another directory. This might be something you could solve.

Hi @steunenberg Checking in, were you able to run it on your machine?

Hi @amit-sharma I tried to find out what was missing in setup.py but I could not find out. As mentioned above, when I'm in the dowhy root directory, the object exists. But somewhere else it does not. This seems a setup.py issue. But I must admit that I did not try that much. Half an hour seemed enough to me.

Hey @steunenberg, just merged an update from @ktmud that may be a fix for this issue. It could be that a PyMC's version was creating a problem. If you get a chance, can you pull the latest master and try if it fixes the problem for you?

Fixed! thank you
