I did that earlier today:
pip install jupyter
pip install numpy
pip install scipy
pip install scikit-learn
pip install matplotlib
The only problem I had was with OpenCV, which requires manual make installation if you want the contrib package. The other problem was when trying to install scikit-learn, it requires manual pip installation of scipy.
- yeukhon 11y agoThe reason you can't is because of the C libraries levaaged must be installed prior to install numpy and scipy. For example, you can't get through PyYaml unless python-dev is installed on Ubuntu. I am not sure if wheel would fix it but I don't think so.
- takeda 11y agoWheel is a binary distribution, so files would already be compiled and therefore python-dev would not be needed anymore.
- yeukhon 11y agoIs wheel not default? Or play it elementary :-) how would I avoid this issue in the future?
- takeda 11y agoI did not write anything worthy to send to PIP so don't know exactly but looks like it is up to the developers[1] Anyway I just noticed that PyPI only supports binary packages for Windows and Mac OS X. Although, you could still generate wheels of packages that you use by using something like this: pip wheel -r requirements.txt You can then install them with pip install <file> or (unfortunately I forgot the option, perhaps it was -i) you can use an option to point to a directory containing wheels and pip install to install the main package. It should use all dependencies in that directory as well. [1] http://pythonwheels.com/ http://pythonwheels.com/
- techdragon 11y agothe issue with Wheels on Linux, and this is very much a Linux problem, is that the 'pre built' nature of libraries in wheels doesnt play nice with the raw chaos of Linux's package management + distro + kernel ecosystem. I raised the question of FreeBSD and Solaris based wheels at a PyCon when I was in a face to face discussion with someone more knowledgeable, and the answer was 'in theory that should work like Windows & OSX, no one has done the hard work yet.' So yeah Linux is not the most friendly environment for Python Wheels.
- timClicks 11y agoI would always be worried with installing numpy/scipy via pip that I wouldn't be linking to BLAS/LAPACK correctly.
