How to properly upgrade numpy on Windows 7?

Question

It seems the whole world is using Linux or Mac, and I couldn't find any answer on the web to question "How to properly upgrade numpy on Windows 7?". I use Windows 7, python 2.7 and numpy 1.7.1, how do I upgrade to numpy 1.9.1 on my machine?

Solution 1

It will be based on your installation.

• First: try pip install --upgrade numpy

Solution 2

My suggestion is uninstall numpy and install again. When you uninstall, it will delete the older version of numpy from your computer. When you install with pip again it will install recent version of numpy.

pip uninstall numpy #removes numpy with older version
pip install   numpy #install new version of numpy
