CCDr algorithm can't run

[chencjiajy]

Describe the bug - cdt version: '0.5.23' - python version: 3.6.9 - no Gpu when I run CCDr algorithm in ipython, it got stucked by hours，the code is snippet in doc:

import networkx as nx
from cdt.causality.graph import CCDr
from cdt.data import load_dataset
data, graph = load_dataset("sachs")
obj = CCCDr()
output = obj.predict(data)

if I use 'ctrl + C' the output is below, it seem RPackages.sparsebn got stucked:

Hello,

Thanks for the feedback, have you tried on other, smaller datasets ? This seems like a inherent CCDr issue (internal to the R library).

Best regards, Diviyan

I have tried other datasets, only about 1000 data. It got stucked too
