do_intervention never ends running despite simple query

[ironcrypto]

Hi QB––

Description

I am running a do-calculus on a small dataset (116x32) with 2 to 4 discretized buckets.
The BN fits the CPDs in 2 sec, so relatively good perf.

However a simple do-intervention takes forever and even never ends running, I waited several hours then I interrupted kernel.

Steps to Reproduce

$ from causalnex.inference import InferenceEngine
$ ie = InferenceEngine(bn)
$ ie.do_intervention("cD_TropCycl", {1: 0.2, 2: 0.8})
$ print("distribution after do", ie.query()["cD_TropCycl"])

Expected Result

Shouldn't it be running just a few seconds given the low number of buckets?
How long does it normally take?

Actual Result

no results returned after hours running a simple query.

Your Environment

Include as many relevant details about the environment in which you experienced the bug:

• CausalNex version used (pip show causalnex): 0.5.0
• Python version used (python -V): python 3.7.6
• Operating system and version: osx 10.15.14 on 2.3 GHz Quad-Core Intel Core i5

Thank you very much!!

Hello @qbphilip
Any chance I get get an answer or help on this?
Thank you

Same problem when I do intervention on a little large dataset. Some nodes can be queried easily while some cannot be.

@ironcrypto Could you replicate this on a minimum example, e.g. on a small synthetic dataset?

[ironcrypto]

@qbphilip yes I think so. Do you have such dataset or should I create it?

Hi @ironcrypto, it would be great if you could provide us this dataset to debug this. Thanks :)

@SteveLerQB
Sure. here attached the Notebook and the dataset to reproduce.
You will see that I interrupted the last two instructions of Do-Calculus as an effect of very high latency.
I would be curious to see if you get the same problem or if error is on my side. Maybe a bad discretization policy? I doubt because it is pretty simple though.

Hi @SteveLerQB @qbphilip
Have you been avale to reproduce the bug or do you observe the same latency?
Thank you

thank you @ironcrypto for reporting this. This is also linked to issue #100. The above has been fixed with this commit will be available in the next CausalNex release.
