Heroku buildpack: Python, Numpy, and Scipy
This is a custom Heroku buildpack for Python apps that use NumPy and/or SciPy, powered by pip.
Note: This buildpack currently only supports the cedar-14 stack. If you
need binaries for the original cedar stack, check out
thenovices' repo
Please open a GitHub for any problems encountered or feature requests.
Details
This buildpack currently supports:
NumPy:
- 1.9.1
SciPy:
- 0.14.0 (compiled against NumPy 1.9.1)
This package will also install compiled runtime libraries for BLAS, LAPACK, ATLAS, and Fortran, which are needed by NumPy and SciPy at runtime.
Usage
For a new app:
heroku create --buildpack https://github.com/andrewychoi/heroku-buildpack-scipy
For an existing app:
heroku config:set BUILDPACK_URL=https://github.com/andrewychoi/heroku-buildpack-scipy
You must specify your exact desired version in requirements.txt (e.g.,
numpy==1.9.0). If no version is specified, the latest version available will
be used. At this time, this buildpack does not support requirements of the
form numpy>=1.8.
Demo
$ mkdir testheroku
$ cd testheroku
$ git init
$ heroku create --buildpack https://github.com/andrewychoi/heroku-buildpack-scipy
$ echo -e "numpy==1.8.1\nscipy==0.14.0" > requirements.txt
$ git add requirements.txt
$ git commit -m 'Added requirements'
$ git push heroku master
