How To Install Python Packages – Part VIII

See the previous installment in this series here to learn more about resolution of frequent user queries.

Query #3: Check for the dependency packages – scikit-learn

Let’s go back to this image once more.

You can see while installing ‘iexfinance’ pip checked for a lot of other Python packages such as requests, pandas etc.,

These are the dependency packages that are required to run ‘iexfinance’ smoothly.

For ‘scikit-learn’ package you can find the dependency packages in the PyPI project description.

You can also see the versions for the dependency packages.

Whenever you try to install or upgrade ‘scikit-learn’, make sure the scipy and numpy packages are also upgraded to their latest versions.

Note: Restart the Kernels

Do not forget to restart the kernels in Jupyter or Spyder before you start using ‘scikit-learn’ package in your code. Otherwise, you would face an error while importing the ‘scikit-learn’ package.

This happens because when you open the Jupyter or Spyder to code they create a Python environment based on the package versions existing at that point of time. So, whenever you install or upgrade a new package you need to restart the kernel too.

In summary, we've seen how to install Python packages and also addressed some of the most frequently asked queries about Python here in this tutorial on how to install Python packages. Hope this helps in creating a smooth journey as you explore Python!
