Compile to .pyd file

[ustcfdm]

Is it possible to compile taichi code into .pyd file? The purpose is to protect source code when I want share my program with others. I tried to compile a python file with taichi code into a pyd file using nuitka. It worked for pure python part, but raised an error for taichi part.

I raised a same issue in Nuitka repo. Details are here: Nuitka/Nuitka#2132

@ustcfdm Taichi uses the inspect module to parse the source code, and it fails to find the source code file when your code is compiled into binary format. I'm not familiar with nuitka, but one possible fix is to let nuitka also includes the source code in the result executable. Maybe you can check nuitka's doc that whether they have such options?

@neozhaoliang Thanks for your suggestion. I am wondering whether there is Python API for Taichi AOT? This should also be a solution for me.

[neozhaoliang]

What about using some third-party lib to obfuscate your python code?

[ustcfdm]

This is a solution, but not my preference. Since Taichi needs the source code to compile, obfuscation does not really protect code. I would prefer AOT for Python API if possible.

The AOT module gives shader output that can be called by C++. The shader output is obfuscated but can still be analyzed by AI. So I doubt AOT is the perfect solution.

I see. This may beyond my understanding and requirement. 😮 It will be okay as long as there is no .py files somehow.

@ustcfdm aha then maybe give taichi AOT a try? It currently doesn't support loading from python but writing pybind for the C++ can be pretty straightforward.

[ustcfdm]

@ailzhang It doesn't support Windows for now. I will give it a try when AOT is supported in Windows system.

[ailzhang]

@ustcfdm btw AOT is supported on Windows ;) Feel free to give it a try and let us know if you hit any issues!
