Modulenotfounderror: no module named ‘sklearn’

Time needed: 3 minutes

Here are the solutions to solve the no module named ‘sklearn’. In your project folder root directory, open the command prompt(CMD).

1. Installing Packages with PIP in the Correct Way

   If you have installed different versions of python on your computer. For every time when you install the module it is related to just a single version.
   
   For this reason, there’s a chance that you may install the module scikit-learn in one of the python versions you installed. Yet you are running the source code with a different version of python and this is one of the reasons why the “scikit-learn” cannot be found.
   
   On the other hand, make sure that you will use the correct command to install “sklearn” through the PIP command. Commonly, several users are trying to install this package using the command.
   
   For Python 2:
   pip install package_name
   
   For Python 3:
   pip3 install package_name
   
   The two above commands are to install the specific package with which the Python library is associated with. For example, you can find out by executing the following command below:
   
   pip –version
   
   After you execute the command above, it will show the pip you install in your computer:
   

2. Install the sklearn module in Python 2:

   This is the command to install the sklearn module in Python 2:
   pip install scikit-learn
   
   
3. Install the sklearn module in Python 3:

   This is the command to install the sklearn module in Python 3:
   python -m pip install scikit-learn
   
   

4. Install the sklearn module in Anaconda:

   You can install the scikit-learn (sklearn) module in Anaconda through these following steps below:
   
   Step 1: Open the Anaconda prompt.
   Step 2: Type the following command and press enter to update conda:
   conda update conda
Step 3: Type the following command and press enter to install scikit-learn:
   conda install scikit-learn
   Step 4: Anaconda will ask you to confirm the installation by typing ‘y’ or ‘n’. Type ‘y’ and press enter.
   Step 5: Anaconda will download and install scikit-learn along with any dependencies.
   Step 6: Once the installation is complete, you can start using scikit-learn in your Jupyter notebook or Python script by importing it with the following line of code:
   import sklearn
   
   That’s it! You have successfully installed scikit-learn in Anaconda.

5. Install the sklearn module in Jupyter

   You can install scikit-learn (sklearn) module in Jupyter notebook by using pip, which is a package installer for Python library.
   
   Here are the steps to install the scikit-learn module in Jupyter notebook.
   Step 1: Open a terminal or command prompt.
   Step 2: Type the following command and press enter to install scikit-learn using pip:
   !pip install scikit-learn
   
   
   
   Note: The exclamation mark (!) is used to indicate that the command should be run in the terminal or command prompt, rather than in the Python environment.
   Step 3: Once the installation is complete, you can start using scikit-learn in your Jupyter notebook by importing it with the following line of code:
   import sklearn
   
   That’s it! You have successfully installed scikit-learn in Jupyter notebook using pip.
