pyAgrum - printing and plotting

Question

I'm just starting to learn pyAgrum. I am looking for functions to both plot a network and print the tables/potentials within a python session. I.e., I'm looking to do this without the need for any sort of HTML-based interpreter (pylab, etc.). I'm coming from the R-world, where I'm used to this kind of workflow using R's version of igraph e.g., and where tables can be printed as ordinary R-arrays. I know, that pyAgrum::Potential's are lower-level C++ classes but is there a way to achieve the above? I like to stay in my editor :)

Answer 1

I already answered you somewhere else :-) but for the sake of the other readers :

• to print an ascii version of a table, you can just use the __str__() methods. Hence print(p) where pis a Potential will do the job.

• to export an image of a BN, you can use pyAgrum.lib.image :

import pyAgrum
import pyAgrum.lib.image as gimg

bn=gum.fastBN("A->B->C")

gimg.export(bn,"test.pdf")
gimg.exportInference(bn,"test.png",evs={"A":1})

will export test.pdf containing the graph and test.png containing the (graphical) result of an inference.
