How to install NumPy on Windows 64?

Question

NumPy installer can't find python path in the registry.

---

Cannot install

Python version 2.5 required, which was not found in the registry.

OK

I have to modify the registry? I already modified %PATH% to point to the Python25 installation directory.

Answer 1

Something is strange with the official superpack...

Windows 64 bit unofficial releases Christoph Gohlke has put together an impressive collection of Windows binary installers of recent versions of scientific packages for Python, including amd64 versions of Numpy and Scipy compiled against Intel's MKL, and SciKits: http://www.lfd.uci.edu/~gohlke/pythonlibs

The unofficial release solved this installation problem.

Answer 2

Numpy is not supported on python 2.5 for Windows 64 bits, you need at least python 2.6, and even in that case, you need to build it by yourself, or use something like EPD or the installer given in link given by thor.

NumPy cannot be used in Google App Engine, so I am not sure to understand the argument there.

Answer 3

can I check what installer you're using for this? I don't think there is an official 64bit Numpy binary, but there is an unofficial one you can try here. Of course, if you've already tried this installer then let me know.
