tf.summary.FileWriter
Class FileWriter
Defined in tensorflow/python/summary/writer/writer.py.
See the guide: Summary Operations > Generation of Summaries
Writes Summary protocol buffers to event files. #将摘要协议缓冲区写入事件文件
The FileWriter class provides a mechanism to create an event file in a given directory and add summaries and events to it. The class updates the file contents asynchronously. This allows a training program to call methods to add data to the file directly from the training loop, without slowing down training.
TensorBoard will pick the graph from the file and display it graphically so you can interactively explore the graph you built. You will usually pass the graph from the session in which you launched it:
...create a graph...
# Launch the graph in a session.
sess = tf.Session()
# Create a summary writer, add the 'graph' to the event file.
writer = tf.summary.FileWriter(<some-directory>, sess.graph)
