python 3.x - Tensorboard Error: No dashboards are active for current data set

Question

I am trying to use Tensorboard but every time I run any program with Tensorflow, I get an error when I go to localhost:6006 to view the Visualization

Here is my code

a = tf.add(1, 2,)
b = tf.multiply(a, 3)

with tf.Session() as sess:
    writer = tf.summary.FileWriter("output", sess.graph)
    print(sess.run(b))
    writer.close()

When I go to the command prompt and enter

tensorboard --logdir=C:pathooutputfolder

It returns with

TensorBoard 0.1.8 at http://MYCOMP:6006 (Press CTRL+C to quit)

When I go to localhost:6006 it states

No dashboards are active for the current data set. Probable causes: - You haven’t written any data to your event files. - TensorBoard can’t find your event files.

I have looked at this link (Tensorboard: No dashboards are active for the current data set) but it doesn't seem to fix this issue

And I am running this on Windows 10

What do I do to fix this issue? Am I giving the right path for Tensorboard in the command prompt?

Thank you in advance

Answer 1

Your issue may be related to the drive you are attempting to start tensorboard from and the drive your logdir is on. Tensorboard uses a colon to separate the optional run name and the path in the logdir flag, so your path is being interpreted as pathooutputfolder with name C.

This can be worked around by either starting tensorboard from the same drive as your log directory or by providing an explicit run name, e.g. logdir=mylogs:C:pathooutputfolder

See here for reference to the issue.
