Question

无法弄清楚为什么CV2无法调整图像大小。我尝试使用不同的图像尺寸，但似乎没有任何效果。 TRAIN_DIR包含大小约为（1000，1700）的.jpg图像。无法弄清楚如何将我的图像获取为numpy数组，并避免函数调整大小时出现错误（-215）ssize.width> 0 && ssize.height> 0


TRAIN_DIR = 'rgupt44/projects/project0/train'
TEST_DIR = 'rgupt44/projects/project0/test'
IMG_SIZE = 500
LR = 1e-3

Model_Name = 'SkinCancer-{}-{}.model'.format(LR, '2conv-basic')


def create_train_data():
    train_data = []
    for img in os.listdir(TRAIN_DIR):
        label =  label_img
        path = os.path.join(TRAIN_DIR,img)
        img = cv2.resize(cv2.imread(path, cv2.IMREAD_GRAYSCALE), (IMG_SIZE, IMG_SIZE))
        train_data.append([np.array(img), np.array(label)])
    shuffle(train_data)
    np.save('train_data.npy', train_data)
    return(train_data)


error                                     Traceback (most recent call last)

      8     shuffle(train_data)

CV2错误：函数调整大小
