我是张量流的新手。我正在关注本教程https://learningtensorflow.com/lesson9/
我的Python env是3.5.2，具有张量流1.9.0和numpy 1.15.0。我在Windows 10平台的Anaconda3中运行python env。该教程中的代码在Jupyter笔记本中运行。
运行时
with tf.Session() as session:
initial_board_values = session.run(initial_board)
X = session.run(board_update, feed_dict={board: initial_board_values})[0]`
我得到如下错误：
