I use the 'pip install scipy' command in the cmd, but get this error at the end. How do I fix it?

  • updated the comment so that it has the entire error – UberKoolMan Apr 12 '16 at 23:06
  • Your problem is with the lack of underlying scientific libraries and according to [this](https://www.scipy.org/scipylib/building/windows.html) page they are a pain to build on Windows. Scipy needs a [whole stack](https://www.scipy.org/install.html) of packages to work properly and the recommended solution is to use precompiled packages as in the answer by @MattDMo. – Ferdinand van Wyk Apr 12 '16 at 23:28

For modules on Windows that require compilation, just use Christoph Gohlke's Python Extension Packages for Windows repository. You can download scipy here, but as indicated you'll need to also install the MKL version of numpy.

Once you have downloaded the .whl files, simply install them with

pip install -U wheel_file_name.whl

The -U is for upgrade, in case you have a previous version installed already.

  • What exactly is the difference between using .whl files and installing directly from pip ? Asking because I spent almost an hour trying to install through pip (I mean PyPi package) but never got it to work. Was almost going to install Anaconda do deal with this but saw your comment and got scipy installed. Thanks. – karun_r May 26 '17 at 04:42

download installer for your version of python from this website: https://github.com/scipy/scipy/releases

There are a lot of files to download from the website but e.g. for python 2.7, the right installer is named scipy-0.16.1-win32-superpack-python2.7.exe After downloading the file, you can easily install Scipy by a few clicks.

  • Except that the latest version of scipy is 0.17.0, and there is no executable installer for it on that page. – MattDMo Apr 12 '16 at 20:46

It seems you have to install cython. I was hitting the same error and "sudo pip install cython" solved the issue. See here build scipy error cythonize failed

In the errors it says: "Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27"
