Tensorboard: No tensorboard, but recognizes event files when running --inspect

[woonsangcho]

Hello,

When I run this:

tensorboard --inspect --logdir=F:\a3c_extension\a3c_github\tensorboard

It recognizes the event files shown as

======================================================================
Processing event files... (this can take a few minutes)
======================================================================

Found event files in:
F:\a3c_extension\a3c_github\tensorboard\PongNoFrameskip-v4_a3c_0.0003\auditor_for_worker_0

These tags are in F:\a3c_extension\a3c_github\tensorboard\PongNoFrameskip-v4_a3c_0.0003\auditor_for_worker_0:

So the files are there. Now when I run the following to visualize in tensorboard:

 tensorboard --logdir=F:\a3c_extension\a3c_github\tensorboard --host=127.0.0.1 --port=6006

It shows

Starting TensorBoard b'54' at http://127.0.0.1:6006
(Press CTRL+C to quit)

and opening in a browser shows tensorboard, but with no information i.e. No scalar data was found. etc.
No graph information as well.

Please let me know why this is so. Thank you!

The general advice that I would give here is to avoid using drive letters (F:\) in the --logdir specification, as TensorBoard uses the colon as a separator. (We consider this a bug—https://github.com/tensorflow/tensorboard/issues/52—but this is how it is right now.) So, normally, I'd suggest cding into F:\a3c_extension\a3c_github\ and just passing --logdir tensorboard.

However, the fact that --inspect yields working data surprises me to some degree. Would you mind trying the above anyway? If that works, then it's just a manifestation of the aforelinked known bug. Otherwise, we can continue to investigate.

cd ing to the directory solved the problem. Thank you!
