I have the same problem as ImportError: DLL load failed: The specified module could not be found (sklearn) but I'm USING Anaconda. The error I get is at bottom. Is there a way to do this uninstall/reinstall separately without breaking my Anaconda install?

I've tried uninstalling and reinstalling scikit-learn. I was about to start uninstalling and reinstalling mkl and numpy but doing so would uninstall a whole host of other packages as well, at which point I'd likely be better off just reinstalling Anaconda from scratch. Except no guarantee I won't end up back at this same problem again if I do so.

Of note, I have a second computer with an Anaconda install that works fine so it must be a problem specific to my installation but I haven't managed to fix it.

I tried the answer from this and got a success.

  1. First uninstall Numpy, Scipy, and Sklearn.
  2. Choose your Numpy+MKL installer from here and put it into the Anaconda Scripts folder.

  3. Reinstall Numpy with MKL using the installer you just downloaded.

    pip install --upgrade --force-reinstall "numpy-1.10.2+mkl-cp35-none-win32.whl"

  4. After that, reinstall Scipy and Sklearn.
