Replace `none_throws` with a direct non-None assertion and remove the unused Buck dependency so OSS installations can import `NativeBackend` without installing `pyre_extensions`. Validated with `pyre_extensions` absent: 62 native preprocessing, partitioner, pass, and PTN export tests passed, plus 14 subtests. Flake8 and ufmt passed. Authored with OpenAI Codex.

…, and Samsung conv1d (#22373) ### Summary Error-guard sites that construct a failure which cannot actually fire. This PR inserts the missing `raise` (or replaces an always-true `assert` with the file's existing `check_or_raise`) so the documented failure mode is the one callers see. Updated for `main` at 5e21c13: the two `ExportSession` guards were fixed upstream in the meantime by #21748, so the only code change left in `export/export.py` is the message typo. The regression tests for those two guards are kept, since nothing else covers them. | File | What happens on `main` today | Reachability | | --- | --- | --- | | `export/export.py` `ExportSession.print_delegation_info` | Both guards already `raise` (#21748). Remaining here: the message says "atleast", and no test pins either guard. | **Reachable.** `ExportSession` is in `executorch.export.__all__` and is `@experimental`. A pipeline with no lowering stage, or one that lists `TO_EDGE_TRANSFORM_AND_LOWER` / `TO_BACKEND` without having run it, reaches each guard. This PR fixes the wording and adds `export/tests/test_print_delegation_info.py` for both. | | `backends/xnnpack/operators/node_visitor.py` per-channel axis `else` | `assert f"Unsupported weight per channel quantization axis ..."`: the f-string is always truthy, so the assertion never fires. An `assert` would also disappear under `python -O`. | **Not reachable on a normal export.** The only call that passes `swap_in_out_for_weights=True` is `backends/xnnpack/operators/op_conv2d.py:102`, and that visitor already `check_or_raise`s the axis to `0` (depthwise) or `1` (transpose) before `define_tensor`. This change restores a guard that can actually raise if that `else` is ever entered; it does not fix a mis-serialized `.pte` on the current conv2d path. | | `backends/samsung/_passes/conv1d_to_conv2d.py` `update_kernel` `else` | `RuntimeError("Weight of 1d conv should be constant tensor or Parameter obj")` is built and discarded; `weight_node.meta["val"]` is still unsqueezed. | **Not reachable on a normal Parameter / lifted-constant / buffer conv1d export.** Those cases are handled by the preceding branches (the buffer branch was added on `main` by #22725). The `else` is the leftover for a weight that is none of those. This change only makes that documented `RuntimeError` actually raise if the branch is entered. | ### Test plan Tests cover only the two reachable `ExportSession` guards. There is intentionally no test for the XNNPACK `else` and none for the Samsung `else`: both are unreachable on a normal export, and a test that injects that state would exercise a situation the production callers do not produce. `export/tests` is already in `pytest.ini` `testpaths`: ``` pytest export/tests/test_print_delegation_info.py ``` Measured on 89cf698 (merge of `main` 5e21c13), CPython 3.12, torch 2.15.0.dev20261004+cpu: - `export/tests/test_print_delegation_info.py`: 2 passed. - Negative control, after `git checkout origin/main -- export/export.py`, same run: `AssertionError: 'at least one of the lowering stages' not found in 'No delegation info available, atleast one of the lowering stages should be present'`, 1 failed / 1 passed. - `pytest export/tests --ignore=export/tests/test_target_recipes.py`: 8 failed / 172 passed on this branch, and the same 8 failed / 170 passed on `main` alone. The 8 are a local-environment gap (`exir/_serialize/program.fbs` is copied in by the build, which this checkout has not run), not a regression. `test_target_recipes.py` does not collect locally (no `coremltools`). ### CI Merged `main` into the branch. The conflict in `export/export.py` was resolved in favour of `main`'s `_raise_if_released` call, keeping the typo fix. The six reds triaged earlier on 12c3858 came from the merge base and their upstream fixes (#22802, #22754) are now in this branch. Two checks are still red on 89cf698, neither of them from this change: - `pull / android / run-emulator`: the emulator boots (`sys.boot_completed` returns 1), and `reactivecircus/android-emulator-runner` then fails on its own post-boot `adb shell input keyevent 82` with `cmd: Failure calling service input: Broken pipe (32)`, exit code 224. That step runs before the job script, and the log carries no output from `scripts/run_android_emulator.sh`. The same job also failed on `main` at efc7f2e when checked on 2026-10-06, and passed on the seven `main` runs before it. - `MLTEC_elastic - GitHubPOC` (NXP Bamboo): outside this repository's workflows, and red on other PRs too, not just this one: of eight open PRs untouched since 2026-10-05, two carry this status and both are red. Here the status went `pending` at 2026-10-05T07:01:25Z and `failure` one second later, which reads as a trigger-side failure rather than anything built from this branch, but the build log is on an internal host so I cannot confirm that from here. This change touches three Python files and adds one test. cc @nil-is-all @digantdesai Co-authored-by: Axel.Cffrd.Dnty <AxelNoun@users.noreply.github.com> Co-authored-by: Claude Opus 5 <noreply@anthropic.com>
