AttributeError: 'numpy.ndarray' object 没有属性 'append' 错误

Question

Hello Guys I am new to Machine and Trying to learn it from you-tube but when i run their code on my computer i got this error Please help....!!!!

Code:

import random

random.shuffle(training_data)

for sample in training_data:
    print(sample[1])

X = []
y = [] 

y = np.array(y)

for features  , label in training_data:
    X.append(features)
    y.append(label)

X  = np.array(X).reshape(-1 , IMG_SIZE , IMG_SIZE,1)

enter image description here

Answer 1

Move your y to numpy to after loop. As @Tyberius mentioned in the comments, you cannot append to numpy array. Therefore, you need to keep y as list in your for loop and then convert it after appending. Like here:

import random

random.shuffle(training_data)

for sample in training_data:
    print(sample[1])

X = []
y = [] 

for features  , label in training_data:
    X.append(features)
    y.append(label)

y = np.array(y)

X  = np.array(X).reshape(-1 , IMG_SIZE , IMG_SIZE,1)
