tf_data_bottleneck_analysis hangs forever upon tf.data profling

[Yan Ni]

I was using tensorflow profiler to profile tf.data pipeline bottleneck. So I wrote a benchmark program which has the following code pieces:

train_set = TrainDataset(...) # create tf.data pipeline
train_data_op = train_set.get_next()
with tf.profiler.experimental.Profile(FLAGS.summary_dir):
    for _ in range(1000):
        _ = sess.run(train_data_op)

which ran remotely and I downloaded the generated profile data to local.

Then I got the following issue:

Hello @leckie-ponyai , what versions of tensorflow and tensorboard and related packages are you using? See that last line:
2022-09-09 17:31:40.786053: W tensorflow/core/profiler/convert/xplane_to_tools_data.cc:191] Could not find host XPlane for tf data stats:
It appears it's unable to find the data to render this.
