This directory provides apure Pythonversion ofpattern_base_pass/1_fuse_matmul_add_pass, with logic consistent with C++FuseMatMulAndAddPass:

• Pattern 0:MatMul(a, b)→Add(..., c), graph inputs0/1/2correspond toa/b/c
• Pattern 1:BatchMatMulV2(a, b)→Add(..., c), same three-input topology
• Replacement:GEMM(r_a, r_b, r_c, alpha=1, beta=1)(scalar1.0aligns with C++CreateScalar(1))
• InheritsPatternFusionPass, implementspatterns()/meet_requirements()/replacement(); phase isBeforeInferShape

No additional matcher configuration likeenable_const_value_match()enabled, consistent with C++ default matching behavior.

Directory Structure

python/ ├── README.md // Python sample documentation ├── CMakeLists.txt // Build script for generating es_all Python ES API ├── src │ ├── python_fuse_matmul_add_pass.py // Python pass implementation file

Prerequisites

• CANN environment variables configured viasource ${ASCEND_PATH}/set_env.sh, see C++ sample README environment configuration steps
• GE Python package importable (includesge.passesand pass loading chain)

run package typically includesge_pywheel, no need to install separatege_py-*.whl. Python pass runtime loadspybind11-based precompiled binary components. CANN package provides artifacts matching current Python version; if no match, fallback compilation occurs automatically. Fallback compilation requirespybind11installed in current Python environment. If execution reports missingBatchMatMulV2,GEMMetc. ES API, follow "ES API Missing Handling (Optional)" below to generate and loades_all.

Usage

Commands below default to execution in1_fuse_matmul_add_pass/pythondirectory.

1. Set environment variable for GE to load this Python pass during compilation:

export ASCEND_GE_PY_PASS_PATH=$PWD/src/python_fuse_matmul_add_pass.py

1. Follow C++ sample README program execution section for verification.

2. Notes:

   • This sample is not a standalone execution script, directly runningpython src/python_fuse_matmul_add_pass.pywon't trigger pass execution
   • If execution reports missingBatchMatMulV2,GEMMetc. ES API, generate and loades_allfirst per below, then rerun

ES API Missing Handling (Optional)

If execution reports missingBatchMatMulV2,GEMMetc. ES API, generatees_allvia this Python directory'sCMakeLists.txt:

cmake -S . -B build cmake --build build --target build_es_all -j$(nproc)

Install generated Python package and ensure current Python process can find the package and corresponding dynamic library:

pip install --force-reinstall --upgrade --target ./build/whl_package ./build/es_output/whl/es_all-1.0.0-py3-none-any.whl export PYTHONPATH="$PWD/build/whl_package:${PYTHONPATH:-}" export LD_LIBRARY_PATH="$PWD/build/es_output/lib64:${LD_LIBRARY_PATH:-}"

Expected Behavior

Similar to C++ sample, when pattern/replacement invoked:

Define pattern for FuseMatMulAndAddPass Define replacement for FuseMatMulAndAddPass
