pyufunc.cvt_py_to_dll

pyufunc.cvt_py_to_dll(py_file, output_dir='')

Convert a Python file to a DLL using Cython and setuptools.

Parameters:

• py_file (str) – The path to the Python file to convert. It should have a .py or .pyx extension.

• output_dir (str) – The directory where the DLL should be saved. Default is current directory.

Raises:

• ValueError – If the provided file is not a .py or .pyx file.

• FileNotFoundError – If the DLL file is not found after conversion.

Notes

• The function uses Cython to compile the Python file into a shared library (DLL).

• It creates a temporary directory to perform the conversion and cleans it up afterwards.

• The output DLL will have the same name as the input Python file (without extension).

Example

>>> import pyufunc as pf
>>> pf.cvt_py_to_dll('example.py', output_dir='output_directory')
>>> # This will convert 'example.py' to 'example.pyd (Windows)/example.so (Linux or Macos)'.
>>> import example # Now you can import the compiled module as a regular Python module.

Returns:

True if the conversion was successful, False otherwise.

Return type:

bool
