Describe the bug
When using the optimizer AdamW within Pytorch, and using Flet Build macos, the application errors with:
"OSError: could not get source code"
It also occurs with NAdam as well.
Note, that Flet Build is still stripping off all bin directories (0.24.1), and these have to be manually inserted to get the code to the failure point, else it will fail due to lack of the bin directory. (see #3060 )
To manually get the bin folder working: Take the bin folder from the development environment, location: /.venv/lib/python3.12/site-packages/torch/bin
and copy it to: /Users/[USER]/Library/Caches/flet_demo-1.0.0-1/app/pypackages/torch
Code sample
Code
```python import flet as ft import torch import torch.nn as nn import torch.optim as optim # Simple model (replace with your actual model) class SimpleModel(nn.Module): def __init__(self): super(SimpleModel, self).__init__() self.fc = nn.Linear(10, 1) # Adjust input/output sizes as needed def forward(self, x): return self.fc(x) # Initialize model and optimizer model = SimpleModel() optimizer = optim.AdamW(model.parameters(), lr=0.001) def main(page: ft.Page): page.title = "PyTorch Model with Flet" # Sample input data input_data = torch.randn(1, 10) def train_click(e): # Sample training loop output = model(input_data) loss = torch.mean(output) # Simple loss for illustration optimizer.zero_grad() loss.backward() optimizer.step() page.snack_bar = ft.SnackBar(ft.Text(f"Loss: {loss.item()}")) page.snack_bar.open = True page.update() page.add( ft.ElevatedButton("Train", on_click=train_click), ) ft.app(target=main) ```To reproduce
To reproduce this error:
Environment Python 3.12.5 (the issue is also present in 3.11.9) Flet 0.24.1 Pytorch 2.3.1
Command: Flet CLI = flet build macos
Expected behavior
The application should operate correctly.
