For example, named attributes, operand and results are usually accessible as properties of the OpView subclass with the same name, such as operation.const_value instead of operation.attributes["const_value"]. If this name is a reserved Python keyword, it is suffixed with an underscore. The operation itself is iterable, which provides access to the attached regions in order: from mlir.ir import Operation operation = <...> for region in operation: do_something_with_region(region)

December 19, 2024Is there any tool that converts python to MLIR language?
Pretty sure the Mojo compiler is open source and has a pipeline to get to mlir dialect. As mojo is a superset of python, this should suit your needs (any python code is also mojo code). I’m sure there are many other tools which fit your use case, but this was the only one that occurred off the top of my head More on reddit.com

Hi everyone! I'm struggling to find the documentation on how to install mlir to use in python, i.e.
import mlir module = mlir.ir.Module.parse(stablehlo_text)
I have been following https://mlir.llvm.org/docs/Bindings/Python/ but where exactly do they install mlir? I eventually get an error at:
python -m pip install -r mlir/python/requirements.txt

It should be possible to compile using a single command of the style "c++ -O3 -shared -fPIC -I/path/to/mlir/includes -I/path/to/llvm/includes -I/path/to/pybind11 -L/path/to/mlir/lib -L/path/to/llvm/lib -lMLIRIR -lMLIREDSC -lMLIRSupport -lLLVM -o mlir_bindings", or using cmake https://pybind11.readthedocs.io/en/stable/compiling.html#building-with-cmake after setting up the include/link locations so that MLIR and LLVM libraries can be found. It should give you a Python binary module that can be loaded as usual in Python.

Python Bindings - tt-mlir documentation
Since most constructors for IR primitives are created in C++, the goal is to construct objects in C++, but have the ownership exposed to Python. We do this through the creation of a Get function. The get function will essentially intake primitive C-types, and invoke the ::get operator in C++ to construct the object. A simple code example for the ttkernel.TileType is shown below: ... // We export the function outside of the scope of "C" such that it can be defined later using C++ methods. MLIR_CAPI_EXPORTED MlirType ttmlirTTTileTypeGet(MlirContext get, unsigned height, unsigned width, uin32_t dataType);

I see filia, where a tool called py2mlir can e used to convert python to mlir. However, the project looks unmaintained as the last commit was 2 years back.
I see codon, which can be used to convert python to llvm but not mlir. I know there are ways to convert from llvm to mlir, with something like mlir-translate --import-llvm. However, that might not include higher level information.
So, is there any maintained tools available that converts python to MLIR LangRef?

There’s torch-mlir for PyTorch.I don’t know about plain python though.

March 10, 2025 - When using any of these print-ir flags, including --mlir-print-ir-tree-dir, the IRs are written to files in a directory tree if you don't want to parse through the terminal stdout. Note: The order of the passes can be important, for example convert-scf-to-cf must come before convert-cf-to-llvm.
