1 week ago Walkthrough
## Walkthrough The recent changes involve a minor alteration in the initialization of `op_info` within the `get_backend_info` method of a class in the `deepmd/pt/entrypoints` module. Previously, `op_info` was set to `None`, but it is now initialized as an empty dictionary `{}`. This adjustment ensures that `op_info` is always a dictionary, simplifying downstream usage and possibly preventing `NoneType` errors. ## Changes | File Path | Change Summary | |----------------------------------------|-------------------------------------------------------------------| | `deepmd/pt/entrypoints/main.py` | Initialized `op_info` as an empty dictionary `{}` instead of `None`. | ## Sequence Diagram(s) Since the changes involve only the modification of the initialization of a variable within a method, no new features or complex control flows have been introduced. Therefore, a sequence diagram is not necessary for this update.Recent review details

117-117: Local variable `f` is assigned to but never used (F841) Remove assignment to unused variable `f` --- 374-377: Use ternary operator `FLAGS = parse_args(args=args) if not isinstance(args, argparse.Namespace) else args` instead of `if`-`else`-block (SIM108) Replace `if`-`else`-block with `FLAGS = parse_args(args=args) if not isinstance(args, argparse.Namespace) else args`

`212-212`: **Good fix to prevent TypeError in dictionary merging.** Changing `op_info` from `None` to `{}` when `ENABLE_CUSTOMIZED_OP` is `False` is a necessary fix to prevent runtime errors during dictionary merging. This change ensures that `op_info` can always be safely merged with other dictionaries.
