Usage:
```python
from dataclasses import dataclass
import datasets

# load and path setting
ds_visdial = datasets.load_dataset('jxu124/visdial')
path_map = {
    "coco/train2014": f"/datasets/coco/train2014",
    "coco/val2014": f"/datasets/coco/val2014",
    "visdial/VisualDialog_test2018": f"/datasets/visdial/VisualDialog_test2018",
    "visdial/VisualDialog_val2018": f"/datasets/visdial/VisualDialog_val2018"
}

# apply to your datasets
@dataclass
class ReplaceImagePath():
    path_map: {}
    def __call__(self, features):
        for k, v in self.path_map.items():
            features['image'] = features['image'].replace(k, v)
        return features
ds_visdial = ds_visdial.map(ReplaceImagePath(path_map=path_map)).cast_column("image", datasets.Image())
