No module named 'catboost'

You are missing catboost package in your Python environment!

You got error message about missing Python package. The error happens when you try to import Python module catboost. The Python complains that catboost module can't be importend because its path is not present in your current Python path.

When using Python srcipt in your terminal your output with error message might look like this:

computer:~$

python -c "import catboost"

Traceback (most recent call last):
File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'catboost'

Are you using Python notebook? Then your code cell with error message looks similar to:

import catboost
---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)      
Cell In[1], line 1
----> 1 import catboost

ModuleNotFoundError: No module named 'catboost'

3 ways to fix - No module named catboost

Don't worry. We will fix the issue. You need to install missing package. We will show you 3 ways of how it can be fixed:

  • - install catboost using pip
  • - install catboost using conda
  • - automatic install of catboost in MLJAR Studio

Why there are three ways to fix this issue? It all depends on which package manager are you using. The most common package manager is pip. The common choice, especially in Windows environments, is conda manager. There are also other Python package managers, for example Poetry, but we don't cover them in this article.

The last way to fix issue, is to use MLJAR Studio. It is a notebook based programming environment that can automatically detect missing Python packages and install them.

How to check if package manager is pip or conda

Are you not sure what package manager are you using? Please try the following command and if you goet the conda version displayed it means that you are using conda package manager:

computer:~$

conda --version

conda 23.11.0
If conda is missing in your environment you will get output similar to:
computer:~$

conda --version

Command 'conda' not found

Please try the below code cell if you are in Python notebook. If you get no error then you are using conda otherwise please use pip for installing new packages.

import sys
!conda list --prefix {sys.prefix}

Install catboost with pip

Please run the following command to install catboost with pip:

pip install catboost

If you are using virtual environment, please make sure that it is activated.

For Python notebook users, please use the following command:

import sys
!{sys.executable} -m pip install catboost

This will ensure that a new package is installed in Python from currently used notebook kernel. You will be able to import catboost package in your notebook.

It is worth to check the PyPi website of catboost. You can check there what is the current version and history of releases.

Install catboost with conda

The catboost package can be installed with the command:

conda install -c conda-forge catboost

If you are in Python notebook, please use the following code:

import sys
!conda install --yes --prefix {sys.prefix} -c conda-forge {entry.installName}

The above code cell ensures you that catboost is installed in the correct environment and will be accessable in your current notebook. Please check catboost conda-forge website to check latest version number and history of releases.
