Looks right to me.

This is correct (cuml is taking ownership of the buffer, so we can't do anything), but I think this is an impossible branch? How could we get here given that if data is a Buffer that exposes get_ptr then it also has a __cuda_array_interface__ property so we'll never end up in this branch?

You are right, we will never branch for a Buffer to this part of the code. Reverted the change.

Can a cuml-ite cast some light on what is meant to be going on in this function? I think that this patch:

Just deletes unreachable code:

Both CudfBuffer and DeviceBuffer advertise a __cuda_array_interface__ property

Only CudfBuffer and DeviceBuffer have a .ptr property

So if data is either a CudfBuffer or a DeviceBuffer then we will never fall through the initial

try: data.__cuda_array_interface__ except AttributeError: ...

check.

@wphicks can you comment?

@wence- Yep, that patch looks right to me. This code was based on an earlier version that did not take advantage of __cuda_array_interface__ at all. To answer the question about what this function is meant to, it helps construct a unified interface for all the data types cuML accepts. This function harvests all the data necessary for the CumlArray to populate a __cuda_array_interface__ or __array_interface__ of its own, even if the original object does not have an array interface.

thanks, I'll submit something as a followup, in the interests of keeping Prem's change as small as possible

Code changes look good, just had the comment about the temporary changes

libcudf is not a depencency of libcuml just for context. These chanes are just temporary to test things, right?

Yup, all the .sh file changes will be reverted before merging this PR. Hence tagged it DO NOT MERGE for now.

Same question as above. Python cuml does use cudf so it makes more sense, but these seem like temporary changes for testing, right?

Yup, same as above

We should probably investigate the test failure we're seeing here rather than just doing a rerun. It looks like we're getting an incorrect array shape for that test, which could certainly be caused by a change to the CumlArray logic. Could we check to see if this is a regression using the Hypothesis reproducer instructions before merge?
