For example, installing of requests package:Įnter this into the Python interactor: import pip Start Slicer as administrator: in the start menu, instead of left-click on the Slicer icon, use right-click, then select More. I’ve tried this on the latest nightly version and it all works well for me! Note that this will change as soon as we standardize on Visual Studio 2015 and switch to python >= 3.5. On windows, it will currently work only for pure python wheels because the official package for python 2.7 are built with a compiler than the one used for the official wheels.
Second, on linux (and most likely macOS), it is indeed possible to pip install official packages (even the including binaries like scipy, tensorflow, …). It for example includes an updated setuptools as well as pip. There are a lot of improvement regarding the python infrastructure. That said, depending on the platform there is way around it.įirst, I suggest you download the latest nightly build of Slicer. Since Slicer bundles its own python, it is generally NOT possible to simply copy python packages (especially the one including binaries) from your own site-packages into the one of Slicer. I tried to copy and paste all the installed packages into the “Slicer 4.6.2\lib\Python\Lib\site-packages” folder, but Slicer ended up not running at all. If I already have Python 2.7 and all packages I want installed on my computer, can I add path in Slicer so it knows where to find those packages?
