Making binary wheels and uploading them to PyPi, would allow to pip install tslearn without needing a compiler or Cython.
Usually this requires quite a bit of work, see e.g. https://github.com/MacPython/scikit-learn-wheels/. However there is a shortcut with https://github.com/regro/conda-press that might allow generating wheels from conda-forge builds. I have not used it yet personally, but it could be worth a try.
