Install Python Development Version
Published: Mon 02 January 2017ByIn.tags:When working on a python project with several dependencies, sometimes I want to see what's going on in one of the required packages. I don't use IDEs so the preferred method of debugging code inside of package dependencies is to grep for an entry point to that package inside of virtualenv, open the source file, add a debug point and re-run test suite or a script until the code hits the debug point.
Figuring out what is the actual problem left as an exercise to the reader.The main issue with the approach above is that when debug console gets activated, it doesn't print out any source code surrounding the debug point, I have to constantly switch between source editor and console hoping that the line printed out in the console matches file lines open in the editor.A better approach is to clone the source package in question and then install it in the current virtual environment with regular install command.

Small business inventory sales program free. NoteThe above installs the ATLAS implementation of BLAS(the Basic Linear Algebra Subprograms library).Ubuntu 11.10 and later, and recent (testing) versions of Debian,offer an alternative implementation called OpenBLAS.Using OpenBLAS can give speedups in some scikit-learn modules,but can freeze joblib/multiprocessing prior to OpenBLAS version 0.2.8-4,so using it is not recommended unless you know what you’re doing.If you do want to use OpenBLAS, then replacing ATLAS only requires a coupleof commands. ATLAS has to be removed, otherwise NumPy may not work. Pip install - user - install - option = '-prefix=' - U scikit - learnThe -user flag asks pip to install scikit-learn in the $HOME/.localfolder therefore not requiring root permission. This flag should make pipignore any old version of scikit-learn previously installed on the system whilebenefiting from system packages for numpy and scipy. Those dependencies canbe long and complex to build correctly from source.The -install-option='-prefix=' flag is only required if Python has adistutils.cfg configuration with a predefined prefix= entry.

64-bit PythonFor the 64-bit architecture, you either need the full Visual Studio orthe free Windows SDKs that can be downloaded from the links below.The Windows SDKs include the MSVC compilers both for 32 and 64-bitarchitectures. They come as a GRMSDKXENDVD.iso file that can be mountedas a new drive with a setup.exe installer in it. For Python 2 you need SDK v7.0:. For Python 3 you need SDK v7.1:Both SDKs can be installed in parallel on the same host. To use the WindowsSDKs, you need to setup the environment of a cmd console launched with thefollowing flags (at least for SDK v7.0).
