Python，Pyinstaller打包含taichi模块的程序

Python版本3.9、taichi版本1.7.1，pyinstaller版本6.9.0

解决方案：

截止20240726官方给到的方案是正常打包是无解的，各位果断放弃！如果有解决的大佬，请提醒我改正。

调整taichi的使用方式，可以正常打包，说明如下：

I manged to get a work around demo working.
It seems the reason is the taichi using inspect to read the source code,
while the pyinstaller pack everyting in to .pyc file,
making the inspect unable to read the source code.
to debug, a simple example to inspect.getsource, whenever inspect.getsource works, the taichi can compile and run the kernel.

python - Problem with inspect using PyInstaller; can get source of class but not function - Stack Overflow

To make it work, I have to put all the kernel code into a seprate file and use import the code dynamically. use importlib rather than import, and also add the path to system enable the exe find the local .py file

## test_inspect.py 
import inspect

import sys
import os

sys.path.append(os.getcwd())

import importlib 

# load the mode dyanically from sys.path
code=importlib.import_module('cc')

import taichi as ti 
ti.init(arch=ti.gpu)

if __name__=="__main__":

   #check the system include the cwd
    print(sys.path)
   
   #try to get the source for code.hello
    ff=inspect.getsourcefile(code.hello)
    print('modelfil',ff)
    src=inspect.getsource(code.hello)
    print(src)

    #test the kernel
    code.hello()
    

#cc.py
import taichi as ti 
#ti.init(arch=ti.gpu)

@ti.kernel
def hello():
    for i in range(100):
        print(i,"hello")

执行，pyinstaller -F -c test_inpsect.py，打包后可正常运行
