ValueError：无法调整此数组的大小：它不拥有其数据

from keras.datasets import cifar10
import numpy as np


(X_train, y_train), (X_test, y_test) = cifar10.load_data()

X_train1 = X_train.copy().ravel()
y_train1 = y_train.copy().ravel()

X_train2 = X_train1.resize(64*64*500)
y_train2 = y_train1.resize(64*64*500)

X_train = X_train2.resize(64*64*500).reshape(64, 64, 1)
y_train = y_train2.resize(64*64*500).reshape(64, 64, 1)

为什么在显式复制数据后出现此错误？该如何解决？

Answer 1

在numpy中使用整形，将行更改为

X_train2 = np.resize(X_train1, 64*64*500)
y_train2 = np.resize(y_train1, 64*64*500)
