Timeline观察速度

这篇写的不错，简单记录一下如何使用。

from tensorflow.python.client import timeline

#Run the graph with full trace optionwith tf.Session() as sess:

run_options= tf.RunOptions(trace_level=tf.RunOptions.FULL_TRACE)

run_metadata=tf.RunMetadata()

sess.run(res, options=run_options, run_metadata=run_metadata)

#Create the Timeline object, and write it to a json

tl =timeline.Timeline(run_metadata.step_stats)

ctf=tl.generate_chrome_trace_format()

with open('timeline.json','w') as f:

f.write(ctf)
