So, if you are serious about your project, you need to either consider building on top of Unix-like platforms and inherit external quality assurance, or (on Windows) you need to anticipate issues of various kinds, and do extensive testing on your own. In fact, 64 bit Windows is not officially supported by NumPy. There are no official NumPy 64 bit builds available for Windows. Python 3.This article is a short note on how to set up NumPy on a 64-bit Windows, and it was originally posted on Jan-Philip Gehrcke’s blog. When you have completed all of the above, each of the following shellĬommands should indicate Python 3.6.1 (or a more recent version of # sudo ln -s /usr/bin/python3.6 /usr/local/bin/python # instead of python2 (may be dangerous, esp. # Do this only if you want python3 to be the default Python Sudo ln -s /usr/local/bin/pip /usr/local/bin/pip3 Sudo ln -s /usr/bin/python3.6 /usr/local/bin/python3 Then, run the following (this works out-of-the-box on 16.10 and If you're using Ubuntu 16.04 LTS, you'll need to use a PPA: sudo add-apt-repository ppa:jonathonf/python-3.6 # (only for 16.04 LTS) Let's suppose that you have a system running Ubuntu 16.04, 16.10, orġ7.04, and you want Python 3.6 to be the default Python. Of course you can alternatively use python3.6 -m pip as well. Pip 18.0 from /usr/local/lib/python3.6/dist-packages (python 3.6) VerificationĪfter this, pip, pip3, and pip3.6 can all be expected to point to the same target: $ (pip -V & pip3 -V & pip3.6 -V) | uniq You prefer to suppress this warning, use -no-warn-script-location. Consider adding this directory to PATH or, if WARNING: The script wheel is installed in '/home/ubuntu/.local/bin' This may sometimes give a warning such as: Installation without sudo curl | python3.6 -user '/home/someuser/.cache/pip' or its parent directory is not owned by theĬurrent user and caching wheels has been disabled. Pip with sudo, you may want sudo's -H flag. Please check the permissions and owner of that directory. Is not owned by the current user and the cache has been disabled. The directory '/home/someuser/.cache/pip/http' or its parent directory The -H flag is evidently necessary with sudo in order to prevent errors such as the following when installing pip for an updated python interpreter: With regard to installing pip, using curl (instead of wget) avoids writing the file to disk. For python3.8, replace 3.6 with 3.8, but it may also first require the python3.8-distutils package. This answer assumes that you have python3.6 installed.
