Question

The given code is showing me the error; I am making the folder under folder under folder according to different classes and its videos. train is folder contains different class folder, every class folder have certain videos. directory of train is something like this;

---train

  ----class1

         ----video11.mp4
         ----video12.mp4
             ...
  ----class2
         ----video21.mp4
         ----video22.mp4
             ...
      ...

I want to create folders of above directory like this;

---train_data

  ----class1
         ----video11
         ----video12
             ...
  ----class2
         ----video21
         ----video22
             ...
      ...

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)

Error:

v_ApplyEyeMakeup_g01_c01.avi

    os.mkdir(dest_dir + '/' + classes + '/' + videos)

My directory is;

I don't know why os.mkdir() is not working, I was using the same code a day before, and it was working with os.mkdir() command. — Tariq Hussain, Aug 05 '21 at 20:13

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
