For anyone else getting this error, this is due to how the example code imports the module.

If you run from dtreeviz import *, you won't get the necessary function.

Use from dtreeviz.trees import dtreeviz instead.

from dtreeviz.

Hi @p42ul I can't find from dtreeviz import *. Can you point me where to look? I'll fix it :)

from dtreeviz.

@parrt My apologies, I can't seem to find it either. I think I may have just mistyped it 🙄
In any case, from dtreeviz.trees import * works.

from dtreeviz.

no problem!

from dtreeviz.

from dtreeviz.trees import *
from dtreeviz.trees import dtreeviz
I have used both libraries but still error occured. Error: module object is not callable

from dtreeviz.

@Mirza-Ahmad can you give us more details, dtreeviz version, code example? That error occurs when you try to use a Python module as if it were a function or callable object.

@tlapusan Hello, why is it that when I run the following code in PyCharm, no plot appears?
from sklearn.datasets import load_iris
from sklearn.tree import DecisionTreeClassifier
import dtreeviz

Load the Iris dataset

iris = load_iris()
X = iris.data
y = iris.target

Train the decision tree model

clf = DecisionTreeClassifier(max_depth=3)
clf.fit(X, y)

Visualize the decision tree

viz = dtreeviz.model(clf, X, y,
feature_names=iris.feature_names,
class_names=iris.target_names)

Display the visualization

viz.view()

from dtreeviz.

Hi @Gejb01 , did you try it from notebook ? to be honest, I didn't try to see the library behavior from pycharm.

from dtreeviz.

@tlapusan Thank you for your reply.Using your method, I obtained the visualization, but cannot save it, and received the following prompt: ''Traceback (most recent call last) Cell In[19], line 1 ----> 1 viz.save('model.svg') AttributeError: 'DTreeVizAPI' object has no attribute 'save'''. Why is this happening?Looking forward to your reply.

from dtreeviz.

@Gejb01 would help to post also your code to better understand your issue :)

maybe this line of code will do your job:
viz_model.view().save("./tree.svg")

from dtreeviz.

@tlapusan Thank you very much for your reply. I can now output the SVG image, but may I ask if it's possible to save it as a PDF file?

from dtreeviz.

I guess you could use an image editor/converter for this.

from dtreeviz.

@tlapusan Thank you very much. By the way, do you have any tuning experience to share?

from dtreeviz.

@tlapusan again help me with the same

1. Classification
   viz = dtreeviz.model(clas,
   X_train,
   y_train,
   feature_names=iris.feature_names,
   class_names=["setosa", "versicolor", "virginica"]
   )
   viz.view()
   this is the code that I am using for some practice point of view but it is showing the below mentioned error.

NameError Traceback (most recent call last)

help me to resolve it

from dtreeviz.

Hi @MitaliJain123, the error indicates that the dtreeviz library is not imported or installed in your environment.

from dtreeviz.

@tlapusan but I checked it several times it is already installed
