The system cannot find the path specified: ‘ ‘

I am trying to split my image data set into train test and val. It has already created the train, test and val folders, but its empty as I keep encountering an error. This is the code I am trying to run on jupyter notebook, I have imported the required libraries like os, numoy, shutil, random:

# # Creating Train / Val / Test folders 

root_dir = 'Desktop/sem_8_project/brain/brain_tumor_dataset/' # data root path
classes_dir = ['no', 'yes'] #total labels

val_ratio = 0.15
test_ratio = 0.05

for cls in classes_dir:
    os.makedirs(root_dir +'train/' + cls)
    os.makedirs(root_dir +'val/' + cls)
    os.makedirs(root_dir +'test/' + cls)

for cls in classes_dir:
    src = root_dir + cls # Folder to copy images from

    allFileNames = os.listdir(src)
    np.random.shuffle(allFileNames)
    train_FileNames, val_FileNames, test_FileNames = np.split(np.array(allFileNames),

and this is the error it shows:

---------------------------------------------------------------------------
FileNotFoundError                         Traceback (most recent call last)

----> 5     allFileNames = os.listdir(src)
      6     np.random.shuffle(allFileNames)
      7     train_FileNames, val_FileNames, test_FileNames = np.split(np.array(allFileNames),

FileNotFoundError: [WinError 3] The system cannot find the path specified: 'Desktop/sem_8_project/brain/brain_tumor_dataset/no'

Answer

In the last 4 lines of code instead of using: allFileNames = os.listdir(src) I used:

    allFileNames = []
    for filename in os.listdir(src):
        img = cv2.imread(os.path.join(src,filename))
        if img is not None: 
            allFileNames.append(img)

This worked for me and the directory error got fixed.
