ImportError: No module named sklearn (Python)

I wanna use scikit-learn. I have typed

pip install -U scikit-learn
pip3 install sklearn

to install it; but when i type 

$ Python
>>> import sklearn

it returns 

ImportError: No module named sklearn

I followed other tutorials, but it doesn't work. Furthermore, my enviroment returns this warning:

If you have installed scikit-learn from source, please do not forget to build the package before using it: run python setup.py install or make in the source directory.

What is the true code to type in the terminal? I tried to type python setup.py installin the terminal but it doesn't work

Solution

  • Make sure that pip and python are the same version. For example if you run pip for python 2.7, it will install the package only in 2.7, and if your python command point to for example python 3.3 interpreter, it will not have that package
