Interestingly we've started getting several CuPy-related test failures with

17:04:41 E   TypeError: Implicit conversion to a NumPy array is not allowed. Please use `.get()` to construct a NumPy array explicitly.

Thanks @jrbourbeau for finding this, it seems that our docker image was picking NumPy 1.19.5, which doesn't contain NEP-35. I'm adding NumPy 1.21 now in rapidsai/dask-build-environment#3. I'll also work on skipping those tests on NumPy < 1.20.

I opened #7982 to address tests that missed the skip mark.

rerun tests

rapidsai/dask-build-environment#3 is merged and new docker images have been built already. Previously failing tests that depend on NEP-35 now pass, but there's still test_set_index_interpolate[cudf] that fails which is being addressed by #7982, when that's merged all gpuCI tests here should pass.

Closing as failures are being resolved elsewhere -- thanks @pentschev!
