Spent 2 hours training a model for it to fail the save with error prefixed with OSError: [Errno 22] Invalid argument :(

For now I'm just adding fail-safe but I am sure it can be written cleaner

custom_save_path = save_model_path
while True:
    try:
        torch.save(transformer.state_dict(), custom_save_path)
        break
    except:
        print("Please enter new save path:")
        custom_save_path = input() 

print("\nDone, trained model saved at", custom_save_path)

研究方向
The error occurs at line 117 of neural style.py when saving the model. The OSError with errno 22 indicates an invalid argument, often due to invalid file path or permissions. Investigate the save model path variable and ensure it is a valid, writable path. Consider adding a try except to catch the error and provide a helpful message, or validate the path before saving. Check if the issue is platform specific (e.g., Windows path restrictions). Also review the linked PRs or comments for additional context.
