AttributeError: 'Namespace' object has no attribute 'checkpoint'

This error message is indicating that you are trying to access an attribute called `checkpoint` on an object of the `Namespace` class, but that attribute does not exist on that object.
The `Namespace` class is used to represent a collection of command-line arguments that have been parsed by the `argparse` module in Python. When you define a set of command-line arguments using `argparse`, you can then parse those arguments into a `Namespace` object using the `parse_args()` method.
If you are trying to access a specific argument value that was parsed into the `Namespace` object, you need to use the name of the argument as the attribute name. For example, if you have an argument called `--checkpoint` and you want to access its value, you would use `args.checkpoint` (assuming `args` is the `Namespace` object returned by `parse_args()`).
If you are still encountering this error, you may want to double-check that you have defined the `checkpoint` argument correctly in your `argparse` code and that you are using the correct attribute name to access its value in your script.
