Hey,
Thanks for the library, it is fantastic to have a python version of CHAID!
I am having issues visualizing the tree model. I get some error about orca and I cannot find a way to solve. Would…

What should be changed in Your code to get an "exhaustive CHAID" version of this algorithm?

Hi again,
Unfortunately, I cannot export the tree graph. Here is a reproducible example:
```
#library
from CHAID import Tree
X = np.array(([1, 2, 3] * 5) + ([2, 2, 3] * 5)).reshape(10, 3)
Y =…
