The error message mentions gcc. Have you installed some mingw version? As of now our windows build is only properly tested with the Visual Studio C++ compiler from appveyor: https://ci.appveyor.com/project/sklearn-ci/scikit-learn I have not tested the build with mingwpy in a while (I am not a windows user my-self). The file not found error makes me think that you might need to cd into the scikit-learn source folder: !!cd D:\_devs\Python01\scikit_learn\sklearn !!python setup.py build_ext --inplace -- Olivier
