Closing as obsolete. This issue originated as ARROW-4387 (2019). The underlying null bitmap has long been reachable from a tensor via `Data().Buffers()[0].Bytes()` (as noted in the 2020 comment), and that is still true on `main`: `tensorBase` exposes `Data() arrow.ArrayData`, from which the validity buffer is accessible. More fundamentally, Arrow tensors are dense by definition in the columnar spec — they do not carry a per-element validity bitmap the way arrays do, so dedicated `IsNull`/`IsValid` accessors on the tensor type are not meaningful. If a concrete use case for tensor-level validity helpers comes up, please open a fresh feature request describing the specific API you'd like. -- This is an automated message from the Apache Git Service.
