Fix LookupError

✅ Solution

The "LookupError: ContextVar 'shell_parent'" in Weights & Biases (wandb) often arises in interactive environments like Jupyter notebooks when wandb's internal process tries to access the shell's parent process information that isn't readily available. To resolve this, explicitly initialize wandb within a defined context; a common fix is to wrap your `wandb.init()` call within an `if __name__ == '__main__':` block, ensuring it's only executed when the script is run directly (not when imported). Alternatively, try setting the environment variable `WANDB_NOTEBOOK_NAME` to bypass the shell parent lookup, for example, `os.environ["WANDB_NOTEBOOK_NAME"] = "my_notebook.ipynb"`.
