I have written this code, but this is showing error, I don’t know why os.mkdir is not working here

import cv2
import os
from tqdm import tqdm

for data_dir, dest_dir in ["train", 'train_data'],["val", 'val_data']:
    for classes in tqdm(os.listdir(data_dir)):
        for videos in os.listdir(data_dir + '/' + classes):
            print(videos)
            print(classes)
            print(dest_dir)
            if not os.path.exists(dest_dir + '/' + classes + '/' + videos):
                os.mkdir(dest_dir + '/' + classes + '/' + videos)

Answer 1

You can use pathlib module from standard library:

import pathlib
import itertools

extensions = ['mp4', 'avi', 'mkv']

videos = itertools.chain.from_iterable([root_dir.glob(f'**/*.{ext}')
                                            for ext in extensions])

for video in videos:
    (video.parent / video.stem).mkdir(exist_ok=True)

You can use makedir module from the OS standard library:

os.makedir()

instead of

os.mkdir()

Because the os has changed some of its commands.

os has changed some of its commands.

Use;

os.makedirs()

instead

   os.makedir()

or you can use mkdir() as well
