tf.estimator.Estimator 不记录任何事件文件，张量板什么也不显示

Question

I'm currently running TensorFlow 1.9.0 . My custom estimator is created with tf.estimator.Estimator , and run without a glitch. However, I don't find any event files under model_dir , and TensorBoard simply shows nothing.

Here's how I setup my estimator:

classifier= tf.estimator.Estimator(
    model_fn=lr_model_fn, model_dir=PATH)

and I open TensorBoard via tensorboard --logdir=tf_models/ --host=127.0.0.1 where tf_models is the dir PATH .

Files logged in model_dir include checkpoint , graph.pbtxt , model.ckpt-* , etc. No events.out.tfevents* files reside there. Is this normal? Did I have something misconfigured?

Answer 1

It may happen when you delete the previously defined model_dir in your Estimator configuration: FileWriter will fail to write in the deleted directory (even a directory with the same path is created).

You can use tf.summary.FileWriterCache.clear() to clear current cache if this happens. You will lose anterior cached summaries though.
