Unable to install Scipy using pip

Question

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

Answer 1

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.
