How to Solve ImportError Cannot Import Name dtreeviz From dtreeviz.trees Error in Python?

The ImportError: Cannot Import Name dtreeviz From dtreeviz.trees error occurs when we tried to import the dtreeviz from dtreeviz.trees class. The main reason for the error is either the module is not properly installed on your system or you are using the new version of the dtreeviz module. Here we will discuss how you can import the dtreeviz module without getting any errors.

When we tried to import the dtreeviz module using the following statement, we got the error:

from dtreeviz.trees import dtreeviz

Now, let us see how we can solve the problem and import the module without having any issues.

Install the dtreeviz module

First, make sure that you have installed the module on your system. If you haven’t installed the module yet, then you can use any of the given statements to install the module depending on your system.

import dtreeviz

Now you can use the treeviz to create or visualize a decision tree.

Visualize Random Forest Using dtreeviz Module

You can visualize the random forest or decision trees using various methods which are discussed in this article. Here we will just go through how we can visualize a random forest using the dtreeviz module.

# importing the modules
import graphviz
from sklearn.tree import export_graphviz

# selecting the first graph
dot_data = export_graphviz(classifier.estimators_[0])

# saving the image
graph = graphviz.Source(dot_data, format='png')
graph

Output:

Here we are visualizing the decision tree inside the random forest module.
