Tensorflow Tensorboard default port

Is there a way to change the default port (6006) on TensorBoard so we could open multiple TensorBoards? Maybe an option like --port="8008"?

In fact there is an option to change the default port ...

tensorboard --logdir=/tmp  --port=8008

You should provide a port flag (--port=6007).

But I am here to explain how you can find it and other flags without any documentation. Almost all command line tools have a flag -h or --help which shows all possible flags this tool allows.

By running it you will see information about a port flag and that --logdir allows you to

also pass a comma separated list of log directories

and you can also inspect separate event-files and tags with --event_file and --tag flags

If you are already in the directory where TensorFlow writes its logs, you should specify the port first:

tensorboard --port=6007 --logdir runs

If you are feeding a directory to logdir, then the order doesn't matter. (I am using TensorBaord 1.8)
