From 08dc10d05e4c73d2d2697ef5b765e8e25b7c3228 Mon Sep 17 00:00:00 2001 From: Aaron Bockover Date: Thu, 1 Dec 2022 22:07:06 -0500 Subject: [PATCH 1/9] Fix TensorType to return new types for shapes instead of type instances This ensures that TensorType is never actually instantiated and instead new TensorType subclasses are created (and cached) for each shape. This is a stepping stone to a fully generic TensorType where the dtype and shape are modeled into the type itself, but it appears that won't be easily realized until we can depend on Python 3.11. Importantly, this adds unit tests to ensure if we can move to a proper generic that behavior will remain the same.
