The warnings are fine (its deprecations in the pandas <-> dask interface). Thank you so much for testing this all out. I will increase the minimal required pandas version to 1.1.0 (which works, I just tested). Thanks for testing 1.2.1 - I tested some time ago with 1.2.0 and it failed, but I will repeat the tests.
