ValueError：无法将大小为 261715968 的数组重塑为形状 (9466,9216)

编程问答 2022-05-02

问题描述

我尝试通过执行以下代码加载测试和训练数据集并成功加载：

print("loading ... ")
X_train,y_train = get_mstar_data("train",128,96)
X_test,y_test = get_mstar_data("test",96)
X_train = np.reshape(X_train,[X_train.shape[0],X_train.shape[1] * X_train.shape[2]])
X_test = np.reshape(X_test,[X_test.shape[0],X_test.shape[1] * X_test.shape[2]])
print(X_train.shape,y_train.shape,X_test.shape,y_test.shape)

但是在重塑数组时，我最终出现了以下错误：

ValueError                                Traceback (most recent call last)

      3 X_test,96)

      5 X_test = np.reshape(X_test,X_test.shape[1] * X_test.shape[2]])
      6 print(X_train.shape,y_test.shape)
