### Describe the bug

When I was in load_dataset, it said "DatasetInfo.__init__() got an unexpected keyword argument '_column_requires_decoding'". The second time I ran it, there was no error and the dataset object worked
```python

### Steps to reproduce the bug
/home/aihao/workspace/DeepLearningContent/datasets/images/images.py
```python
from logging import config
import datasets
import os
from PIL import Image
import csv
import json


class ImagesConfig(datasets.BuilderConfig):
    def __init__(self, **kwargs):
        super(ImagesConfig, self).__init__(**kwargs)


class Images(datasets.GeneratorBasedBuilder):
    def _split_generators(self, dl_manager: datasets.DownloadManager):
        return [
            datasets.SplitGenerator(
                name=datasets.Split.TRAIN,
                gen_kwargs={"split": datasets.Split.TRAIN},
            )
        ]

    BUILDER_CONFIGS = [
        ImagesConfig(
            name="similar_pairs",
            description="simliar pair dataset,item is a pair of similar images",
        ),
        ImagesConfig(
            name="image_prompt_pairs",
            description="image prompt pairs",
        ),
    ]

    def _info(self):
        if self.config.name == "similar_pairs":
            return datasets.Features(
                {
                    "image1": datasets.features.Image(),
                    "image2": datasets.features.Image(),
                    "similarity": datasets.Value("float32"),
                }
            )
        elif self.config.name == "image_prompt_pairs":
            return datasets.Features(
                {"image": datasets.features.Image(), "prompt": datasets.Value("string")}
            )

    def _generate_examples(self, split):
        data_path = os.path.join(self.config.data_dir, "data")
        if self.config.name == "similar_pairs":
            prompts = {}
            with open(os.path.join(data_path ,"prompts.json"), "r") as f:
                prompts = json.load(f)
            with open(os.path.join(data_path, "similar_pairs.csv"), "r") as f:
                reader = csv.reader(f)
                for row in reader:
                    image1_path, image2_path, similarity = row
                    yield image1_path + ":" + image2_path + ":", {
                        "image1": Image.open(image1_path),
                        "prompt1": prompts[image1_path],
                        "image2": Image.open(image2_path),
                        "prompt2": prompts[image2_path],
                        "similarity": float(similarity),
                    }
```

Code that indicates an error:
```python
from datasets import load_dataset
import json
import csv
import ast
import torch
data_dir = "/home/aihao/workspace/DeepLearningContent/datasets/images"
dataset = load_dataset(data_dir, data_dir=data_dir, name="similar_pairs")
```

### Expected behavior

The first execution gives an error, but it works fine

- `datasets` version: 2.14.3
- Platform: Linux-6.2.0-26-generic-x86_64-with-glibc2.35
- Python version: 3.11.4
- Huggingface_hub version: 0.16.4

Comments:
Thanks for reporting, but we can only fix this issue if you can provide a reproducer that consistently reproduces it.

@mariosasko Ok. What exactly does it mean to provide a reproducer

To provide a code that reproduces the issue :)

@mariosasko I complete the above code, is it enough?

@mariosasko That's all the code, I'm using locally stored data

Does this error occur even if you change the cache directory (the `cache_dir` parameter in `load_dataset`)?

@mariosasko I didn't add any parameters for catch. Nor did any cache configuration change.

@mariosasko And I changed the data file, but executing load_dataset is always the previous result. I had to change something in images.py to use the new results. Using 'cleanup_cache_files' is invalid! Help me.

@mariosasko I added a comprehensive error message. Check that _column_requires_decoding is being passed where it shouldn't be. DatasetInfo.__init__() Whether this parameter is required

I can see the issue now... 

You can fix it by returning a `DatasetInfo` object in the `_info` method as follows:
```python
    def _info(self):
        if self.config.name == "similar_pairs":
            features = datasets.Features(
                {
                    "image1": datasets.features.Image(),
                    "prompt1": datasets.Value("string"),
                    "image2": datasets.features.Image(),
                    "prompt2": datasets.Value("string"),
                    "similarity": datasets.Value("float32"),
                }
            )
        elif self.config.name == "image_prompt_pairs":
            features = datasets.Features(
                {"image": datasets.features.Image(), "prompt": datasets.Value("string")}
            )
        return datasets.DatasetInfo(features=features)
```

@mariosasko Oh, that's the problem. Thank you very much. Returned the wrong object and it actually works? I've been training with it for a long time

@mariosasko The original code can still see progress. emmm, I can't see how many examples is generated so far, so I don't know if we should wait

The original issue has been addressed, so I'm closing it. 

Please open a new issue if you encounter more errors.
