There was a problem hiding this comment.
This doesn't actually test ndonnx's None case until #232 gets merged.

CI failure seems unrelated |

dask arrays of unknown shape return NaN in their
.sizeand.shapeproperties. This was chosen a long time before the Array API standard existed, but alas diverges from the array API standard itself:ndonnx, another library which can have arrays of unknown shape, uses None instead.
This PR changes the
size()function to make dask conform to the standard and adds units tests which were previously missing.Q: Should we add a
shape()function to cover for Dask's.shapeproperty non-standard behaviour?
