Hi all, I am a newbie in PyPy. But with some experience in CPython, and also OpenCV-Python binding and OpenCV-Julia binding.I want to bring OpenCV into PyPy. Then use PyPy to do my research.
First, I read some PyPy and RPython document in recent days. I want to wrap OpenCV in PyPy in "low level". Like OpenCV-CPython, it use Python-C API and Numpy C-API to wrap function and class. Then write a autowrap script to wrap it. In this way, OpenCV-CPython can communicate with NumPy array type. If my understanding is correct. NumPy-PyPy wrote in RPython, wrap the corresponding C and Fortran function. I want wrap OpenCV in PyPy just like OpenCV-CPython. Let NumPy ndarray hold the image matrix. But RPython documentation said "It(Write with RPython) cannot be used by any 3rd-party module". Does it mean if wrap OpenCV in PyPy with cffi. OpenCV-PyPy could not use ndarray? I plan to use RPython, but RPython documentation said it need rebuild PyPy it self, and the module write in RPython will become a built-in module. Rebuild PyPy seems unacceptable in OpenCV-PyPy. Is there has a way to wrap OpenCV in PyPy that could communicate with NumPy-PyPy and without rebuild PyPy it self? Please correct me if my understanding was wrong. Regards, Sun
