Installing Python Scikit-Learn

Question

I'm running the command "pip3 install scikit-learn", and the command prompt spits out the following error:

reading manifest file 'scikit_learn.egg-info\SOURCES.txt'

I know my numpy+MKL and Scipy are both up to date, along with my C++ Redistributable. Any idea what could cause this?

Answer 1

Install it from here http://www.lfd.uci.edu/~gohlke/pythonlibs/ . If you use python 3.6 and win64 download scikit_umfpack‑0.2.3‑cp36‑cp36m‑win_amd64.whl this one.

Answer 2

Can you try with Anaconda ? https://www.continuum.io/downloads#windows After installing anaconda you can create a virtual environment with conda: conda create -n myenv python=3.5

After that you will activate the evn source activate myenv (myenv)$ conda install scikit-learn

This works for me
