Hello, I’m trying to create progress bar using tqdm package.  
Here is my code

```auto
import numpy as np
import os
from glob import glob
from PIL import Image
from tqdm.notebook import tqdm

path = glob('dataset/mnist_png/training/*/*.png')

height = []
width = []

for i in tqdm(path):
    img_pil = Image.open(path)
    image = np.array(img_pil)
    h, w = image.shape
    height.append(h)
    width.append(w)

```

However, progress bar does not changing and stops like this, even though the calculation is done  
0%| | 0/60000 [00:00\<?, ?it/s]

Is there any way to make progress bar changing?  
I am looking forward to see any help. Thanks in advance.  
Kind regards,  
Yoon Ho

Already, your code seems to have a problem : you still use path in the loop

```auto

for p in tqdm(path):

    #img_pil = Image.open(path) 

    img_pil = Image.open(p) 

    # ...

```

The code works for me without any problem.

```auto

import numpy as np

import os

from glob import glob

from PIL import Image

#from tqdm import tqdm

from tqdm.notebook import tqdm

path = glob('/content/*.png')

height = []

width = []

print("")

for p in tqdm(path):

    img_pil = Image.open(p)

    image = np.array(img_pil)

    print(image.shape)

    h, w, _ = image.shape

    height.append(h)

    width.append(w)

```

Thanks for your answer.  
However, even though I replaced path to p, my bar still stops at  
0%| | 0/60000 [00:00\<?, ?it/s]
