How to fix the error? " Valueerror: setting an array element with a sequence'

Python

There is train variable of list type, which conatains two elements - array of img type variables and the array of labels. I need to write the first array(of imgs) to X and then process it with reshape. I used NumPy library.

The code below is for understanding what train variable is.

training_data.append([np.array(img), np.array(label)]) 
   ... 
 train = train_data[:-500]

I have tried to do it two ways.
First i have had the error:
TypeError: 'int'object is not subscriptable

For the second way i have had the error:
ValueError: setting an array element as a sequence

Update: the code, where training data list was create. The train is the slice of training_data

def create_train_data(): 
    
    training_data = [1100] 
  
   
    for img in tqdm(os.listdir(TRAIN_DIR)): 
  
       
        label = label_img(img) 
  
        path = os.path.join(TRAIN_DIR, img) 
  
        training_data.append([np.array(img), np.array(label)]) 
  
        shuffle(training_data) 
  
       np.save('train_data.npy', training_data) 

    return training_data 

    train_data = create_train_data() 
    train = train_data[:-500]

There is what print(train) gives

What I have tried:

First way:

X = np.array([i[0] for i in train]).reshape(-1, IMG_SIZE, IMG_SIZE, 1)

Second way:

MyX=np.asarray( train[0])
X = MyX.reshape(-1, IMG_SIZE, IMG_SIZE, 1)
