@matbryan52 there are some deprecation warnings emitted from test_random_set_with_array which I couldn't figure out - feel free to have a look if you find some time (or want to procrastinate)

Other than that, this should be ready to go, and especially for the data tests reduce the number of warnings significantly.

Fixed in the code itself as well as the testcase. Relates to numpy/numpy#10615

👍 yeah - I fixed a few instances of this in the I/O code (and also in rosettasciio), but wasn't entirely sure how to apply that in the dask wrapper stuff. Thanks for taking care of it!
