1. Create a virtual environment and activate it:

python3 -m venv venv
source venv/bin/activate

2. Install required packages:

pip install -r requirements.txt

3. Check if the installation was successful:

python3 -m mlir_wheel --root-dir

4. Configure CMake:

mkdir build
cd build
cmake ../ -DCMAKE_PREFIX_PATH=$(python -m mlir_wheel --root-dir) -DLLVM_EXTERNAL_LIT=$(which lit)

5. Build:

1. Install the Python DSL package (editable mode):

# From project root directory (not the build directory).
pip install -e python/

2. Set the TUTORIAL_OPT environment variable to point to the built tutorial-opt binary:

export TUTORIAL_OPT=$PWD/build/tutorial/tutorial-opt

3. Run an example to verify:

python tutorial/ch1-cpu-vector-dsl/square.py

The examples will print the generated MLIR at each lowering stage.

Each tutorial chapter has a README.md file explaining how to start with the exercise and some basic explanation of the exercise. For example, check out tutorial/ch1-cpu-vector-dsl/README.md
