Ich versuche, die Verwendung meiner Tensorflow-Modelle mit Timeline zu überwachen. Dieser Link erklärt, wie man es benutzt: https://stackoverflow.com/a/37774470/6716760. Das minimale Beispiel hierfür ist:Tensorflow-Kernel stürzt ab, wenn ich versuche, trace_level = tf.RunOptions.FULL_TRACE
import tensorflow as tf
from tensorflow.python.client import timeline
x = tf.random_normal([1000, 1000])
y = tf.random_normal([1000, 1000])
res = tf.matmul(x, y)
# Run the graph with full trace option
with 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)
Leider ich folgende Fehlermeldung erhalten, wenn ich versuche, das Skript auszuführen:

Der Fehler in der letzten Zeile am Ende versteckt ist. Aber was bedeutet das? Wie kann ich es beheben?
Dieser Thread könnte einige hilfreiche Informationen bieten: https://github.com/tensorflow/tensorflow/issues/2626 –
