Pass flags to pip to install a project from a commit version

[Victor Escorcia]

Hi,

I want to install a package from a commit version in a reproducible way. It is possible that YAML-file explicitly mentions (and reproduce) the appropriate behavior.

I describe two hacks around below (based on SO answer) but I want to know if this is the best reproducible YAML that I can distribute?

Hack using conda

This will create a folder called "src" inside your project that you can't delete.

name: daps-eccv16

dependencies:

- h5py=2.6.0=np111py27_2

- hdf5=1.8.17=1

- libgfortran=3.0.0=1

- mkl=11.3.3=0

- nose=1.3.7=py27_1

- numpy=1.11.2=py27_0

- openssl=1.0.2j=0

- pandas=0.19.1=np111py27_0

- pip=9.0.1=py27_0

- psutil=5.0.0=py27_0

- python=2.7.12=1

- python-dateutil=2.6.0=py27_0

- pytz=2016.7=py27_0

- readline=6.2=2

- scipy=0.18.1=np111py27_0

- setuptools=27.2.0=py27_0

- six=1.10.0=py27_0

- sqlite=3.13.0=0

- tk=8.5.18=0

- wheel=0.29.0=py27_0

- zlib=1.2.8=3

- pip:

  - "--editable=git+https://github.com/Theano/Theano.git@88648d8d5531deb4e5e4201a3663ffbc1465b84d#egg=theano-master"

  - "--editable=git+https://github.com/Lasagne/Lasagne.git@9886da26df40cbde9222d4e20706b4b21bbdb627#egg=lasagne-master"

Hack using shell

1. Remove the package that you install with PIP from your YAML file.
   
2. Create bash script that:
1. Create the environment from the YAML file
2. Activate the environment
3. Install the package that you want using pip

Thanks in advance!

This is an excellent use case for creating a conda package for your special versions, and keeping them on an anaconda.org channel.

There is already a good recipe for theano that should get you started:

https://github.com/conda-forge/theano-feedstock

For lasagne, you might be able to use conda-skeleton:

conda skeleton pypi lasagne

For both of these recipes, you will then use conda-build to build the packages.  Conda-build can also upload them for you to Anaconda.org.

I hope this helps you get started.  Sorry I don't have time to write more detailed instructions.

Thank you Michael. This is a more principled solution ;)
