Python TensorFlow张力板问题

我跟在后面。我已经逐字复制了代码，所以没有看到任何错误。 当我尝试添加这一行为TensorBoard创建文件时出现错误：

logs_path = '/tensor_board'
writer = tf.summary.FileWriter(logs_path, graph=tf.get_default_graph())
# RUN
sess.run(init, writer)

当我运行整个代码时，Python会将此作为错误返回：

Traceback (most recent call last):
  File "tf_number_recon.py", line 39, in <module>
    sess.run(init, writer)
  File "C:\Python35\lib\site-packages\tensorflow\python\client\session.py", line 766, in run
    run_metadata_ptr)
  File "C:\Python35\lib\site-packages\tensorflow\python\client\session.py", line 913, in _run
    feed_dict = nest.flatten_dict_items(feed_dict)
  File "C:\Python35\lib\site-packages\tensorflow\python\util\nest.py", line 171, in flatten_dict_items
    raise TypeError("input must be a dictionary")
TypeError: input must be a dictionary

---

进行这些更改后，代码运行不会出现任何问题

logs_path = './tensor_board' 

sess.run(init)

logs_path = './tensor_board' 

sess.run(init)
