Error occur when execute function in Houdini python shell

[QQQQQQinyan]

It shows errors when I run a function made in Houdini python shell

ti.init() [Taichi] Starting on arch=x64 @ti.kernel ... def foo(): ... print("hello") ... foo()

Coule be fixed when install the pyreadline package In windows, dive into the python folder of the installation directory of Houdini. python -m pip install pyreadline However, it print into the Houdini Console instead of the python shell

Hi @QQQQQQinyan This issue is pretty complicated: Taichi use custom source inspect module to locate the python file, and build AST from the file, however, it's hard to locate code written in Python SOP or houdini python shell, since we have no idea what houdini does to code in its shell.

So, alternative to this,

You‘d better write your taichi-scope function/kernel into a .py file, like this https://github.com/taichi-dev/taichi_houdini/blob/master/Libs/python/fractal.py, and put it into somewhere like package/scripts/python so you could import it into houdini, and then import this module and call it inside houdini python shell or python sop.

Hope that answer your question!
