DEPRECATED

All of the code in this project has been submitted upstream to LLVM/MLIR.

linalgpy - Experimental linalg python frontend

This project is just some prototyping of a python frontend to the MLIR Linalg code generator. If it works out, we will upstream it to LLVM.

Setting up

Requires pre-release MLIR python bindings:

# Optional but recommended - create a virtual environment.
python -m venv ~/.venv/linalg
source ~/.venv/linalg/bin/activate

# Install deps.
# Note that MLIR wheels are from the pre-release index.
pip install -r requirements.txt -f https://github.com/stellaraccident/mlir-py-release/releases

Since this is aiming for upstream, it lays out tests for execution via lit and FileCheck. lit comes in via the above requirements.txt but FileCheck must be on your path. If you built LLVM, it is in the build tree. If you installed a recent LLVM, you likely have it but with a version suffix like FileCheck-10: In this case create a symlink to FileCheck.

Testing

lit test -v

In order to run a test manually, you will need to set your PYTHONPATH as:

PYTHONPATH=. python test/tc_model.py

Checking types
