datasets.BuilderConfig does not work.
Opened by jdm4pku (closed)

### Describe the bug

I custom a BuilderConfig and GeneratorBasedBuilder.
Here is the code for BuilderConfig
```
class UIEConfig(datasets.BuilderConfig):

    def __init__(
            self,
            *args,
            data_dir=None,
            instruction_file=None,
            instruction_strategy=None,
            task_config_dir=None,
            num_examples=None,
            max_num_instances_per_task=None,
            max_num_instances_per_eval_task=None,
            over_sampling=None,
            **kwargs
    ):
        super().__init__(*args, **kwargs)
        self.data_dir = data_dir
        self.num_examples = num_examples
        self.over_sampling = over_sampling
        self.instructions = self._parse_instruction(instruction_file)
        self.task_configs = self._parse_task_config(task_config_dir)
        self.instruction_strategy = instruction_strategy
        self.max_num_instances_per_task = max_num_instances_per_task
        self.max_num_instances_per_eval_task = max_num_instances_per_eval_task
```
Besides, here is the code for GeneratorBasedBuilder.
```
class UIEInstructions(datasets.GeneratorBasedBuilder):
    VERSION = datasets.Version("2.0.0")
    BUILDER_CONFIG_CLASS = UIEConfig
    BUILDER_CONFIGS = [
        UIEConfig(name="default", description="Default config for NaturalInstructions")
    ]
    DEFAULT_CONFIG_NAME = "default"
```

Here is the load_dataset
```
raw_datasets = load_dataset(
        os.path.join(CURRENT_DIR, "uie_dataset.py"),
        data_dir=data_args.data_dir,
        task_config_dir=data_args.task_config_dir,
        instruction_file=data_args.instruction_file,
        instruction_strategy=data_args.instruction_strategy,
        cache_dir=data_cache_dir,  # for debug, change dataset size, otherwise open it
        max_num_instances_per_task=data_args.max_num_instances_per_task,
        max_num_instances_per_eval_task=data_args.max_num_instances_per_eval_task,
        num_examples=data_args.num_examples,
        over_sampling=data_args.over_sampling
    )
```
Finally, I met the error.
```
BuilderConfig UIEConfig(name='default', version=0.0.0, data_dir=None, data_files=None, description='Default config for NaturalInstructions') doesn't have a 'task_config_dir' key.
```

I debugged the code, but I find the parameters added by me may not work.

### Steps to reproduce the bug

https://github.com/BeyonderXX/InstructUIE/blob/master/src/uie_dataset.py

### Expected behavior

```
BuilderConfig UIEConfig(name='default', version=0.0.0, data_dir=None, data_files=None, description='Default config for NaturalInstructions') doesn't have a 'task_config_dir' key.
```

### Environment info

torch                     2.3.0+cu118
transformers              4.40.1
python 3.8

Comments:
I guess the issue is caused by the customization of BuilderConfig that you use from the repo [https://github.com/BeyonderXX/InstructUIE](https://github.com/BeyonderXX/InstructUIE/blob/master/src/uie_dataset.py). You should report to them.

I see you already opened an issue in their repo:
