python-3.x - 名称错误 : name 'sess' is not defined

Question

我在 tensorflow 下运行 python 程序。当我输入sess.run()时，命令行提示我NameError: name 'sess' is not defined

print(sess.run(W_conv1))
Traceback (most recent call last):

  File "<ipython-input-17-cf7d3892efbb>", line 1, in <module>
    print(sess.run(W_conv1))

NameError: name 'sess' is not defined

Answer 1

您必须定义sess。在访问它之前放置此行。

sess = tf.Session()

甚至您可以使用 with 语句:

with tf.Session() as sess:

    #Do something with sess
    print(sess.run(W_conv1))
