copy to a dense format
This is exactly what I'd like to avoid -- COO
should be doable though.
I believe we can do this. The main challenge I have a hard time designing for is the selection of an appropriate output format. If we know the appropriate output format, I don't think it would be so hard to do a direct copy. We would need to use one of the randomly accessible sparse formats if the swizzles don't match up. I think we could implement something similar to the style of our getindex kernel, where we use a generated function to write some Finch code and call it.
@mtsokol Is this is a blocker for you?
@willow-ahrens It's needed for doing https://github.com/willow-ahrens/finch-tensor/pull/48 cleanly.
hmm. Okay! I'll do it today then.
Hi @willow-ahrens,
I wanted to discuss feasibility of eager only (and simplest possible)
reshape
function in Finch.It looks like most of the Array API test suites require
reshape
to run (test_signatures.py
test suite that I ran to count the number of supported functions is an exception).To run them locally I used a crude/test only implementation:
Do you think it would be feasible to have an eager only
reshape(::SwizzleArray, ...)
? Even if it would be as simple as copy to a dense format ([EDIT] or COO?), reshape and then copy back to the original format?
