MatxScript is an ahead of time compiler for a subset of the Python language.

Installation
-------
```bash
pip install matxscript
```


A Quick Example
-------
```python
import matx
import timeit

def fib(n: int) -> int:
    if n <= 1:
        return n
    else:
        return fib(n - 1) + fib(n - 2)


if __name__ == '__main__':
    fib_script = matx.script(fib)
    
    # test on Macbook with m1 chip
    print(f'Python execution time: {timeit.timeit(lambda: fib(30), number=10)}s')  # 1.59s
    print(f'Matx execution time: {timeit.timeit(lambda: fib_script(30), number=10)}s') # 0.03s
```

Acknowledgement
---------------
We learned a lot from the following projects when building MatxScript.
- [TVM](https://github.com/apache/tvm): Part of MatxScript's IR and Runtime
  originates from TVM. We also learned and adapted some part of codegen pipeline from TVM.

- [Python](https://github.com/python/cpython/tree/3.8): Part of the runtime code comes from cpython for align the semantics

- [Folly](https://github.com/facebook/folly): We adopted the idea of FBString to design our runtime::string_core

- [abseil-cpp](https://github.com/abseil/abseil-cpp): The string_view structure and ByteHash algorithm originates from abseil

- [rapidjson](https://github.com/Tencent/rapidjson): The json module is implemented based on rapidjson

- [CV-CUDA](https://github.com/CVCUDA/CV-CUDA): The vision CUDA runtime is developed using the operators provided by CV-CUDA.
