ImportError: Failed to import pydot. You must install pydot and graphviz for ‘pydotprint’ to work error occurs when “pydot library or Graphviz is absent in your environment.” This is often encountered when visualizing models in deep learning libraries like TensorFlow and Keras.
How to fix it?
To fix the ImportError: Failed to import pydot. You must install pydot and graphviz for `pydotprint` to work error, install the below libraries one by one:
Solution 1: Using pip
pip install pydot pip install pydotplus pip install graphviz
After installing the required packages, you may need to restart your Jupyter kernel, IDE, or terminal session to ensure the new packages are recognized.
By following these steps, you should be able to resolve the ImportError and use the pydotprint function or other functionalities that rely on pydot and Graphviz.
Solution 2: Using conda
If you are using the conda package manager on Windows, uninstalling and reinstalling pydot + pydotplus fixed the issue on my Windows 10 machine using Anaconda 3.
conda uninstall pydot conda uninstall pydotplus conda uninstall graphviz
And then install the packages using these commands:
conda install pydot conda install pydotplus
Installing pydot will also install the graphviz library.
Install Graphviz on Ubuntu
sudo apt-get install graphviz
Install Graphviz on macOS
brew install graphviz
Install Graphviz on Windows
You can download the Graphviz installer from the official Graphviz website. Follow the instructions provided on the site to install it on your system.
I hope following these steps will fix your error.
