Something seems wrong with the pip package

[blaggacao]

In [2]: import vrp_cli

In [3]: vrp_cli.lib
Out[3]: <Lib object for '/home/blaggacao/src/.../env/lib/python3.10/site-packages/vrp_cli/native.so'>

In [4]: vrp_cli.lib.solve_pragmatic
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

AttributeError: cffi library '/home/blaggacao/src/.../env/lib/python3.10/site-packages/vrp_cli/native.so' has no function, constant or global variable named 'solve_pragmatic'

I couldn't find the publishing routine in the repo automation so I assume publishing to pip is done manually from your local machine.

Maybe somehow something went wrong for this version, that I use:

  "vrp-cli~=1.21.0",

v1.19.2 is good, btw:

In [2]: import vrp_cli

In [3]: vrp_cli.solve_pragmatic
Out[3]: <function vrp_cli.vrp_cli.solve_pragmatic(problem, matrices, config)>

Yeah, need to see what I did wrong with maturin and local Python environment. Or maybe it is better to spend some time and setup dedicated github actions. Need to find some time for it..

As workaround, you can try to build the package locally using maturin as described here: https://reinterpretcat.github.io/vrp/examples/interop/python.html#using-maturin

I got myself into an environment that builds with nix shell nixpkgs#cargo nixpkgs#rustc nixpkgs#maturin. Let me see how far I can get from there.

And that looks actually like it built successfully:

I've added a dedicated github action [1] to build and publish to PyPI, but cannot make it work as it fails with You are running out of disk space. The runner will stop working when the machine runs out of disk space. Free space left: 43 MB. Tried multiple times with reduced amount of architectures, cleaning deps, project's target folder.. No luck so far

I was able to publish update (1.21.1) to PyPI using dedicated github action, so it should work now on different OS families (windows, macos, linux) and architectures (x86_64, armv7), see https://github.com/reinterpretcat/vrp/blob/master/.github/workflows/maturin.yaml
