vsketch VS pip

The frames' vector data is generated using a sketch made with my vsketch framework (it involves loading GeoJSON data, processing it with Shapely, and projecting it in 3D with NumPy).

There isn't a GUI, but that's by design. The CLI format facilitates the integration in automated workflows. The show command does provide a viewer for visualisation at any point in the pipeline. Also, I have another framework (based on vpype) named vsketch which is a plotter-centric python clone of Processing with a viewer and live refresh.

Matplotlib for plotter stuff seems tedious indeed ! Definitly check out vsketch, it has an API similar to processing, but focused on generating plotter-ready SVG.

I started by using Processing, but have switched to [vsketch](https://github.com/abey79/vsketch), a Python-based framework which has a similar API to Processing. I like it because it has built-in UI for changing parameters, which I find hugely useful. Plus, it integrates with vpype, which is designed for image processing for plotters.

Whenever you are working on a Python project that has external dependencies installed with pip, it is strongly recommended to first create a virtual environment.

Unfortunately that feature is easy to break: https://github.com/pypa/pip/issues/9644

I think I did my part https://github.com/pypa/pip/issues/6409

$ sudo pip install y$ sudo pip install yaml WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip. Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue. To avoid this problem you can invoke Python with '-m pip' instead of running pip directly. ERROR: Could not find a version that satisfies the requirement yaml (from versions: none) ERROR: No matching distribution found for yaml

What are you implying will happen?

Using the build-in tools, you can save the exact versions of dependencies (i.e. a lock file) using "pip freeze >dependencies.txt". This should give you the exact same set of packages in two years' time.

If you want to be even more sure, you can also store hashes in the lock file. This has to be generated by a separate tools at the moment [1][2] but can be consumed by the built-in tools [3], so "pip install -r requirements.txt" is still all you need in two years' time.

Here’s the issue, https://github.com/pypa/pip/issues/11664. I think the idea would be to have some file/json description of environment that could be passed to pip to allow it to fully cross compile. They are open to supporting it just needs contributor to be found to implement it and go through review/discussion.

To be fair the only alternative is fixing Python, and even then you still would have to wait a good 5 years at least for all the old Python versions to dwindle.

It doesn't look like the fixing effort is progressing very quickly: https://github.com/pypa/pip/issues/8606

To their credit, at least they didn't close it "works as intended" which I imagine a lot of projects would.

Another good benchmark to trying to resolve apache-airflow[all]==1.10.13 using the state of PyPi on 2020-12-02, I give instructions here on how to reproduce that workflow: https://github.com/pypa/pip/issues/11836. Including a benchmark how how many extra packages your resolver should visit.
