chore(deps): bump AiDotNet.Tensors to 0.129.7 - #2057
Conversation
Required for the crash-evidence capture in #2056 to do anything. That pr sets aidotnet_gpu_diagnostics_dump, but the variable is only read by AiDotNet.Tensors code that landed in ooples/AiDotNet.Tensors#995, which ships in 0.129.7. The pin here is 0.129.4, so today that knob names a variable nothing in the test host reads. With this bump a shard that dies leaves the gpu launch journal and buffer residency totals alongside the sequence file. Those counters are the half a dump does not give cheaply: a host holding gigabytes of device buffers looks, in every managed tool and in a heap dump, like a process with a small tidy heap, because the managed wrappers are tiny and collectible while the native allocations are not visible to them. Chasing the recent tensors shard deaths they identified a 1.1 gb device allocation as the cause and ruled out a buffer leak that had looked like the obvious culprit. 0.129.5 through 0.129.7 are patch releases. Blocked until ooples/AiDotNet.Tensors#992 publishes 0.129.7. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GomYPttAfrJzkoFBJx7nv4

Review caught that bumping AiDotNet.Tensors alone broke the lockstep this file documents: the comment ends "All four packages stay on the published lockstep release", and the natives were left at 0.129.2 while Tensors moved to 0.129.7. They had already drifted behind master's 0.129.4. 0.129.7 is published on nuget for OpenBLAS, OneDNN and CLBlast as well as Tensors, so all four now move together and the rationale is updated to say so.

Why this exists
#2056 does nothing without it. That PR sets
AIDOTNET_GPU_DIAGNOSTICS_DUMPon the shard test step, but the variable is only read byAiDotNet.Tensorscode that landed in Tensors#995 and ships in 0.129.7. This repo pins 0.129.4, so today that env var names a variable nothing in the test host reads.I should have queued this alongside #2056 rather than noting the dependency and moving on.
What it unlocks
With the bump, a shard that dies leaves the GPU launch journal and the buffer residency totals next to the
Sequence.xmlnaming the test in flight.Those counters are the half a process dump doesn't give you cheaply. A host that dies holding gigabytes of device buffers looks — in every managed tool and in a heap dump — like a process with a small, tidy heap, because the managed wrappers are tiny and collectible while the native allocations aren't visible to them. Chasing the recent Tensors shard deaths, they identified a 1.1 GB device allocation as the cause and ruled out a buffer leak that had looked like the obvious culprit (5,885 allocated, 41 live at exit).
Blocked on
Tensors#992 publishing 0.129.7. Draft until then — the restore will fail against a version that does not exist yet.
0.129.5 → 0.129.7 are patch releases.
