Not able to install "lifetimes" package using pip script.
Need urgent help.

Followed the following links for help, but still no success

Since you're on Python 3.5, you'll need Visual Studio 2015 to build extensions.

However, since the extension in question is numpy, you'll need to find prebuilt binaries since you won't be able to compile it yourself just yet. I believe Continuum has builds for 3.5 in Anaconda now.

You can build NumPy with only a C compiler, but it won't have accelerated BLAS/LAPACK. However, lifetimes requires SciPy, which in turn requires Fortran. This is a common requirement with a lot of the scientific-computing stack, so you may as well choose a complete solution such as Anaconda.

That said, if you just need a few packages, then Christoph Gohlke provides an extensive collection of wheels 1. For example, I have a directory with the following wheels downloaded from Christoph's site:

C:\>dir /b Z:\Python\wheel
matplotlib-1.5.0-cp35-none-win_amd64.whl
numpy-1.10.2+mkl-cp35-none-win_amd64.whl
pandas-0.17.1-cp35-none-win_amd64.whl
scipy-0.16.1-cp35-none-win_amd64.whl

I'll test installing lifetimes and matplotlib in a virtual environment:

C:\>py -3 -m venv --symlinks C:\Temp\env35
C:\>C:\Temp\env35\Scripts\activate.bat

The command-line option "-f directory" makes pip look for packages in a local directory:

(env35) C:\>pip install -f Z:\Python\wheel lifetimes matplotlib

Debashish: questions on using pip should be directed to python-list, also accessible as newsgroup gmane.comp.python.general at news.gmane.org. pip is otherwise maintained separately from CPython and has its own bug-reporting system.
