build conda package from local python package

Question

I can't find a complete example of how to create a conda package from a python package that I wrote and also how to install the package using conda install, while it is on my computer and not on anaconda cloud. I'm looking for example that not using conda skeleton from pypi, but using a python package on my windows machine, the source code must be on my windows machine and not on pypi or other cloud. any help would be mostly appriciate. thanks very much

Answer 1

I think it should be trivial if you use the editable way to install packages with conda. I did:

conda develop .

in the project directory (where my setup.py file is).

If you want an example of a setup.py here is mine:

from setuptools import setup
from setuptools import find_packages

setup(
    name='ml', #project name
    version='0.1.0',
    description='ML',
    #url
    author='Me',
    author_email='[email protected]', #not a real e-mail
    license='MIT',
    packages=find_packages(),
    install_requires=['torch','numpy','scikit-learn','scipy','matplotlib','pyyml']
)

The file above is at the root of the project (I do a github repo named project and inside I make a project project with all the packages I develop there.

I believe pip -e . will do the same. You shouldn't need to sudo anything.

A local source directory can be specified in the metadata file meta.yaml by using:

  source:
     path: ../src

https://docs.conda.io/projects/conda-build/en/latest/resources/define-metadata.html#source-from-a-local-path

Additionally, to package your own program you have to define the steps needed to build and install it (for instance, running setup.py install for a python script that uses setuptools: https://setuptools.readthedocs.io/en/latest/index.html) in the files build.sh for linux and bld.bat for windows.
