| - **Python import flow**: framework selection happens in `transformer_engine/__init__.py` (driven by `NVTE_FRAMEWORK`); native `.so` resolution happens in `transformer_engine/common/__init__.py`. Start tracing from these two files for any import or framework-selection issue — function names inside may change, but the entry points are stable. | ||
| - **Build orchestration**: `setup.py` + helpers in `build_tools/` + CMake. ROCm vs CUDA backend detection lives in `build_tools/utils.py` — grep there (and for `NVTE_USE_ROCM`) for current behavior. | ||
| - **3rdparty submodules**: read `.gitmodules` for the current set and commit pins to determine current submodules. | ||
| - **AITER source**: the tree QoLA/TE actually builds is cloned on-demand to `3rdparty/QoLA/build/third_party/aiter` at the commit pinned in `transformer_engine/common/ck_fused_attn/qola_manifest.toml`. The in-tree `3rdparty/*/aiter` checkouts are stale — read the built tree (and check its HEAD) when reasoning about the linked ABI. |
