r/learnpython on Reddit: Question about installing scikit-learn using pip
December 15, 2021 -
Just as a preface, I should say I'm a complete beginner that's only started learning python in the last few weeks.
I came across a question that wanted me to write a function that minimised the mean squared error/deviation for a list of integers.
I looked online about how to solve this and it seems both numpy and scikit-learn are 2 modules that can be used to solve this problem.
I then looked up how to install modules which instructed me to use the command prompt.
For numpy, I simply opened up the command prompt and typed in:
pip install numpy
That instruction was what I found on the numpy website and this seemed to work.
I then tried to install scikit-learn by typing in the following in the command prompt:
pip install -U scikit-learn
However, despite the fact that was the command prompt listed on the scikit website, there were a lot of issues (just a wall of red text after a minute or so) and tbh I just closed the command prompt in a panic.
From looking online, I read that typing in '-U' between 'install' and 'scikit...' was an error because the '-U' implies I already have scikit-learn installed and I just want to update it. Another fact that I found was that in order to install scikit-learn I first have to install scipy.
Can anyone tell me what I should do to install scikit-learn?
Having installed numpy already, is it enough to simply type in:
pip install scipy
Wait for that to install and then type in:
pip install scikit-learn
Any replies would be appreciated

First things first - make sure you are using a virtual envronment, either through PIP or conda. https://duckduckgo.com/?q=why+use+a+virtual+environment+python Second, for beginnersm Anaconda is very helpful becuase it comes with all the popular packages including those you mentioned, pre-installed and ready to use out of the box. https://www.anaconda.com/products/individual If you do this you don't have to worry about a virtual environment i mentioned about, Anaconda does it for you. Main benefit, you won't have to worry about questions like the one posted this while you increase your skills and knowledge. BTW I almost guarantee critics will complain that it's bloated etc, but 1) that's the point, it's all included, you can easily uninstall when you are ready and 2) those people are mostly developers who don't apprecate that there are other use cases for python. Anaconda is widely used in academia and data science for the exact reasons i mentioned. To anwer your question if you want to do it yourself without Anaconda - do a virtual environment, activate it and then yes just type in pip install scikit-learn. You don't need to do pip install scipy. It is a formal dependency and will be automatically installed for you if you don't already have it, same with numpy.

Answering some stuff: -U (same as --upgrade) will upgrade the package if it is there, if not, it will install it from zero (so it's not a problem) Environments are recommended (so you can use different programs with different packages, without one interfering with each other, think of like each project having a separate house to work on) One of the dependencies of scikit-learn is scipy. You usually don't need to worry about it, because pip will automatically install scipy for you when it installs scikit-learn. I don't know what error happened with you. Can you paste the full thing that appeared (specially the red lines?). I assume it may be trying to compile something, so try running the following command: python -m pip install --upgrade pip setuptools wheel

We ‘pip install scikit-learn’, but we ‘import sklearn’ in python code , why? | by G Wang | Medium
April 2, 2024 - The package name used in pip install is defined by the package's developers for the Python Package Index (PyPI) and does not have to strictly match the Python import statement. Here's why this happens in the case of Scikit-learn: Package Naming vs. Module Naming: The package name (scikit-learn) is chosen to be descriptive and adheres to PyPI naming conventions, while the module name (sklearn) is chosen for simplicity and ease of use in code.

You didn't provide us which operating system are you on? If it is a Linux, make sure you have scipy installed as well, after that just do
pip install -U scikit-learn

The --user flag ask pip to install scikit-learn in the $HOME/.local folder therefore not requiring root permission. This flag should make pip ignore any old version of scikit-learn previously installed on the system while benefiting from system packages for numpy and scipy.
