Tensorboard: Can't run tensorboard after successful bazel build

[xiaohk]

I downloaded the tensorboard-1.5.0 release, and bazel build tensorboard:tensorboard. After installing tensorboard, I got the following error when running tensorboard.

JayWong tensorboard $ tensorboard

A logdir must be specified when db is not specified. Run `tensorboard --help` for details and examples.

You need to invoke tensorboard with --logdir path/to/your/tensorflow/logdir.
