images_per_class = 80
fixed_size       = tuple((500, 500))
train_path       = "dataset/train"

train_labels = os.listdir(train_path)
for training_name in train_labels:
dir = os.path.join(train_path, training_name)
current_label = training_name
   for x in range(1,images_per_class+1):
    # get the image file name
    file = dir + "/" + str(x) + ".jpg"

    # read the image and resize it to a fixed-size
    image = cv2.imread(file)

In my case, it didn't like the '~' symbol used in Mac to route to Documents with '~/Documents' so I changed it to '../../../Documents'

You can add below lines before initializing file_name:

import os
os.chdir(folder_address_which_contain_your_file)

it worked for me

Check if such a file really exists. If it gives an error, put it at the same address as the image or the file, for example: the location of your file is C:\Desktop with this name polarbear.jpg. The location of the file where you write the code is C:\Desktop\Files\Python Let it be called kod.py. The code will give an error because your file and your code are not at the same address. Try putting the file and the code at the same address. My file: C:\Desktop\Files\Python\polarbear.jpg My code: C:\Desktop\Files\Python\code.py if you do this solution do not write all of the path just the file name. Example: "polarbear.jpg" Same thing happend to me also I looked for every solution and I couldnt fix it when I was messing around I found the problem. It realy works

in my case it was the filename extension that caused problems. Check whether your png/img/bmp is a png/img/bmp or something else ;)

Make sure that the file name does not contain any special characters, OpenCV seems to be quite sensitive here.

For me the problem was that it contained some umlauts (ä, ö, ü).

Dears, for me the issue was related to filename extension. I put the extension .JPEG whereas the actual extension was .jpg. Correcting the extension cleared the warning. thanks

file = dir + "/" + str(x) + ".jpg"

try to replace this line with :

file = dir + "\" + str(x) + ".jpg"

the / not correct

the correct is \
