Beschreibung

I introduced the pytorch module. When executing the compilation, the following error was reported. How should I solve this problem?

```
Building component my-server with `componentize-py -w spin-http componentize my_server -o target/app/my_server.wasm`
Traceback (most recent call last):
File "/Users/ken/Work/Workspace/spin/myenv/bin/componentize-py", line 8, in
sys.exit(script())

AssertionError: Traceback (most recent call last):
File "/0/my_server.py", line 4, in
from strategy import get_strategy_result
File "/0/strategy.py", line 1, in
from torch import tensor
File "/1/torch/__init__.py", line 14, in
import ctypes
File "/python/ctypes/__init__.py", line 8, in
from _ctypes import Union, Structure, Array
ModuleNotFoundError: No module named '_ctypes'
```

the strategy.py is:
```
from torch import tensor

def get_strategy_result():
# Create a tensor
x = tensor([1.0, 2.0, 3.0])
# Perform a simple operation
y = x * 2
return y

if __name__ == "__main__":
print(get_strategy_result())
```

The version of componentize-py is 0.16.0
my plantform is MacBook Pro
the version of Python is 3.11.10

Rechercherichtung

Start with the componentize-py 0.16.0 compilation command and the provided strategy.py, then reproduce the import failure on Python 3.11.10 on macOS. Trace why importing torch reaches ctypes without _ctypes; done means the reported PyTorch module can compile successfully or the supported limitation and required setup are clearly documented.
