Pyproject.toml missing package-data, index files not installed

[dsuedholt]

If you pull the repo from the master branch at the latest commit (cb25046), local setup with pip install . won't copy over the index files. This can be tricky to reproduce / check, because the indexes folder might still be cached in build folder from previous builds. This causes pip install . to copy the folder over, even though it's not included in pyproject.toml.

To reproduce:

• set up a completely fresh conda env or venv
• freshly clone the mirdata repo, or run rm -rf build mirdata.egg-info to make sure nothing is left cached from previous builds
• install mirdata with pip install . --no-cache-dir again avoiding any caches
• cd .. or cd ~ or similar to leave the mirdata folder, making sure that import mirdata refers to the installed library and not the local module
• python -c "import mirdata; d=mirdata.initialize('maestro'); print(d.track_ids[0])" will now fail with a FileNotFoundError.
  • alternatively, confirm that the folder printed by python -c "import mirdata; print(mirdata.__file__)" does not contain the indexes folder

Adding a package-data subtable into pyproject.toml fixes this.
