Writing to files from jupyter notebook

Question

I tried to run this code:

from tqdm.auto import tqdm
import os
from datasets import load_dataset

dataset = load_dataset('oscar', 'unshuffled_deduplicated_ar', split='train[:25%]')

text_data = []
file_count = 0

for sample in tqdm(dataset['train']):
    sample = sample['text'].replace('\n', ' ')
    text_data.append(sample)
    if len(text_data) == 10_000:
        # once we git the 10K mark, save to file
        filename = f'/data/text/oscar_ar/text_{file_count}.txt'
        os.makedirs(os.path.dirname(filename), exist_ok=True)
        with open(filename, 'w', encoding='utf-8') as fp:
            fp.write('\n'.join(text_data))
        text_data = []
        file_count += 1
# after saving in 10K chunks, we will have ~2082 leftover samples, we save those now too
with open(f'data/text/oscar_ar/text_{file_count}.txt', 'w', encoding='utf-8') as fp:
    fp.write('\n'.join(text_data))

and i get following PermissionError:

Permission Error

I've tried changing rights to this directory and running jupyter with sudo privilages but it still doesn't work.
