Hi @pranav-sridhar 
Have you encountered a similar issue with this dataset?
I’ve modified the dataset construction script to address the problem. Feel free to use this updated version to avoid the issue.

### Describe the bug

When using the `filter` or `map` function to preprocess a dataset, a ValueError is encountered with the error message "array is too big; arr.size * arr.dtype.itemsize is larger than the maximum possible size." 

Detailed error message:
Traceback (most recent call last):

### Steps to reproduce the bug

```python
from datasets import load_dataset, DatasetDict
from transformers import WhisperFeatureExtractor
from transformers import WhisperTokenizer

samromur_children= load_dataset("language-and-voice-lab/samromur_children")
feature_extractor = WhisperFeatureExtractor.from_pretrained("openai/whisper-small")
tokenizer = WhisperTokenizer.from_pretrained("openai/whisper-small", language="icelandic", task="transcribe")

def prepare_dataset(batch):
    # load and resample audio data from 48 to 16kHz
    audio = batch["audio"]

    # compute log-Mel input features from input audio array 
    batch["input_features"] = feature_extractor(audio["array"], sampling_rate=16000).input_features[0]

    # encode target text to label ids 
    batch["labels"] = tokenizer(batch["normalized_text"]).input_ids
    return batch

cache_dict = {"train": "./cache/audio_train.cache", \
              "validation": "./cache/audio_validation.cache", \
              "test": "./cache/audio_test.cache"}
filter_cache_dict = {"train": "./cache/filter_train.arrow", \
                "validation": "./cache/filter_validation.arrow", \
                "test": "./cache/filter_test.arrow"}

print("before filtering")
print(samromur_children)
#filter the dataset to only include examples with more than 2 seconds of audio
samromur_children = samromur_children.filter(lambda example: example["audio"]["array"].shape[0] > 16000*2, cache_file_names=filter_cache_dict)   
print("after filtering")
print(samromur_children)
processed_dataset = DatasetDict()
# processed_dataset = samromur_children.map(prepare_dataset, cache_file_names=cache_dict, num_proc=10,)
for split in ["train", "validation", "test"]:
    processed_dataset[split] = samromur_children[split].map(prepare_dataset, cache_file_name=cache_dict[split])
```

### Expected behavior

The dataset is successfully processed and ready to train the model.
