小编Log*_*ase的帖子

我在 Windows 10 上使用 Tensorflow 1.4.0 和 Python 3.6。我查看了其他关于值排序的帖子，但到目前为止没有发现任何有用的东西。

谢谢。

import tensorflow as tf
import numpy as np
from sklearn.datasets import fetch_california_housing

housing = fetch_california_housing()
m, n = housing.data.shape
housing_data_plus_bias = np.c_[np.ones((m, 1)), housing.data]

#normalization
scaled_housing_data_plus_bias = tf.nn.l2_normalize(housing_data_plus_bias, 1, epsilon=1e-12,name="Normalized")


n_epochs = 1000
learning_rate = 0.01

#error occurs here
X = tf.constant(scaled_housing_data_plus_bias, dtype=tf.float32, name="X")
