IPython magic command interface for interactive work with mypyc.

Project description

mypyc_ipython

IPython magic command interface for interactive work with mypyc, a compiler from type-annotated Python to C extensions.

Installation

Supported Python versions are 3.6 or later.

$ pip install mypyc-ipython

Usage

You can use this library like %%cython magic command.

  1. Execute %load_ext mypyc_ipython to enable the magic.
  2. Write the code in %%mypyc code cell.
In [1]: %load_ext mypyc_ipython

In [2]: %%mypyc
   ...: def my_fibonacci(n: int) -> int:
   ...:     if n <= 2:
   ...:         return 1
   ...:     else:
   ...:         return my_fibonacci(n-1) + my_fibonacci(n-2)
   ...:

In [3]: my_fibonacci(10)
Out[3]: 55

In [4]: def py_fibonacci(n: int) -> int:
   ...:     if n <= 2:
   ...:         return 1
   ...:     else:
   ...:         return py_fibonacci(n-1) + py_fibonacci(n-2)
   ...:

In [5]: py_fibonacci(10)
Out[5]: 55

In [6]: %load_ext cython

In [7]: %%cython
   ...: cpdef int cy_fibonacci(int n):
   ...:     if n <= 2:
   ...:         return 1
   ...:     else:
   ...:         return cy_fibonacci(n-1) + cy_fibonacci(n-2)
   ...:

In [8]: cy_fibonacci(10)
Out[8]: 55

In [9]: %timeit py_fibonacci(10)
10.3 µs ± 30.2 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

In [10]: %timeit my_fibonacci(10)
848 ns ± 5.82 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

In [11]: %timeit cy_fibonacci(10)
142 ns ± 1.18 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

In [12]:

The contents of the cell are written to a .py file in the directory IPYTHONDIR/mypyc using a filename with the hash of the code. This file is then mypycified and compiled. The resulting module is imported and all of its symbols are injected into the user's namespace.

If you want to disable the cache, you can use --force option like this:

In [2]: %%mypyc --force
   ...: def my_fibonacci(n: int) -> int:
   ...:     if n <= 2:
   ...:         return 1
   ...:     else:
   ...:         return my_fibonacci(n-1) + my_fibonacci(n-2)
