Shape of a vector is ambiguous #41

From reading the spec, it seems that it's ambiguous what we should put under the key shape when the format is DVEC. Do we want shape: 100? shape: [100]? Or shape: [100, 1]?

In order to work well with tensors, I'm guessing we want shape: [100], but we need to make sure it's unambiguous in the spec, and preferably add some examples.

@willow-ahrens @eriknw and @ivirshup, do you have opinions here? If we have consensus, I'll go update the spec.

My opinion: clarify that vectors (including DVEC) are shape e.g. [100] (not 100).

willow-ahrens commented 11 months ago

Yes! This allows scalars to be shape []
