Tensorflow Tensorboard default port

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

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

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