Install numpy on python 2.7 windows

Note In this case, we are using bit binaries of Python packages. But if you want to use OpenCV for x64, bit binaries of Python packages are to be installed. Problem is that, there is no official bit binaries of Numpy. Installing Numpy on 64bit Windows 7 with Python 2. Download by right click. NumPy for Python 2. For many users, especially on Windows, the easiest way to begin is to download one of these Python distributions, which include all the key packages.

What do you mean "on windows this won't work"? That's how I installed numpy on my Windows environment… Of course you need to install a C compiler and follow the instructions to get it working, but at some point you're going to run into a library that Gohlke doesn't have, or need a newer version, so it really is worth learning how to do… — abarnert. Sometimes they don't have the library compiled for windows. In the past numpy has not worked for me; maybe it is working now. Getting compilation set up on Windows is not trivial, especially for something like numpy.

If the OP is on windows, it is probably useful to have a solution that is based on running an executable installer. BrenBarn: Saying "on Windows this will not work" isn't a judgment call, it's just plain wrong. Saying "on Windows you may not want to do this", that's a different story, and in fact, I'd agree.

Almost all users should start off with Gohlke's libraries, at the very least to make sure their setup works and they understand it, before learning to build things. The fact that he's downloading a file from that site suggests he's not using pip.

And if you're not using pip to install the library, either a you're using binary installers for your platform whether Christoph Gohlke's or something that comes from an apt or rpm repo or similar , in which case you just need to choose the right binary, or b whatever you're doing, you should stop doing that and instead use pip , in which case this answer will fix all your problems.

BrenBarn: I included an alternative solution already using setup. Your PATH isn't setup correctly. Community Bot 1 1 1 silver badge. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name.

Otherwise: Install Miniforge. Use Poetry as the most well-maintained toolthat provides a dependency resolver and environment management capabilitiesin a similar fashion as conda does. Python package management Managing packages is a challenging problem, and, as a result, there are lots oftools.

Reproducible installs As libraries get updated, results from running your code can change, or yourcode can break completely. Besides install sizes, performance and robustness, there are two more things toconsider: Intel MKL is not open source.

For normal use this is not a problem, but ifa user needs to redistribute an application built with NumPy, this could bean issue. Often all CPU cores will be used. It typically yields better performance, but can also beharmful - for example when using another level of parallelization with Dask,scikit-learn or multiprocessing. Troubleshooting If your installation fails with the message below, see TroubleshootingImportError.
