Muna Compiler

Muna compiles stateless Python functions to run anywhere. This project is a playground for testing the Muna compiler. Over time, we expect to open-source more and more of the compiler infrastructure in this project.

Setup Instructions

First, install Muna for Python:

# Run this in Terminal
$ pip install --upgrade muna

Next, head over to the Muna dashboard to generate an access key. Once generated, sign in to the CLI:

# Login to the Muna CLI
$ muna auth login <ACCESS KEY>

Compiling a Function

The predictors directory contains several prediction functions, ranging from very simple functions to AI inference with PyTorch. Internally, we use these functions to test language and library coverage in the compiler. To compile a function, first update the predictor tag with your Muna username:

@compile(
    tag="@username/some-function", # replace `username` with your Muna username
    description="Compile a cool function."
)
def grader (score: float) -> str:
    ...

Next, use the Muna CLI to compile the function, providing the path to the module where the function is defined:

# Compile the decorated function at the module path
$ muna compile --overwrite path/to/module.py

The compiler will load the entrypoint function, create a remote sandbox, and compile the function:

Inspecting the Generated Code

Once you compile a function, you can download the generated C++ code:

# Retrieve the generated C++ source code for a given predictor
$ muna source --predictor @username/some-function

Note

Because our compiler can generate hundreds of implementations for a given predictor, we recommend using muna source --prediction <id> to get the generated C++ code for a specific prediction. The provided id must have been provided directly by our API.

Warning

The generated C++ code is provided for reference and cannot be compiled independently, as it depends on additional scaffolding provided by the Muna compiler toolchain.
