Describe the bug

I met an error when running a notebook provide by Hugging Face, and met the error.

TypeError: 'NoneType' object is not callable

I have checked my internet, it worked well. And the dataset name was just copied from the Hugging Face.
Totally no idea what is wrong!

Steps to reproduce the bug

To reproduce the bug you may run

from datasets import load_dataset, Dataset

# Load the enhancers dataset from the InstaDeep Hugging Face ressources
dataset_name = "enhancers_types"
train_dataset_enhancers = load_dataset(
        "InstaDeepAI/nucleotide_transformer_downstream_tasks_revised",
        dataset_name,
        split="train",
        streaming= False,
    )
test_dataset_enhancers = load_dataset(
        "InstaDeepAI/nucleotide_transformer_downstream_tasks_revised",
        dataset_name,
        split="test",
        streaming= False,
    )

Expected behavior

1. what may be the reasons of the error
2. how can I fine which reason lead to the error
3. how can I save the problem

Hi ! I couldn't reproduce on my side, can you try deleting your cache at ~/.cache/huggingface/modules/datasets_modules/datasets/InstaDeepAI--nucleotide_transformer_downstream_tasks_revised and try again ? For some reason datasets wasn't able to find the DatasetBuilder class in the python script of this dataset
