I'm able to use TensorFlow just fine. But I can't yet use TensorBoard at all. I'm following the instructions on tensorflow.org's Visualizing Learning page.
When I run
tensorboard --logdir=/tmp/mnist_logs --debug
I get the following
INFO:tensorflow:TensorBoard is in debug mode.
INFO:tensorflow:Starting TensorBoard in directory /private/tmp/mnist_logs
INFO:tensorflow:TensorBoard path_to_run is: {'/tmp/mnist_logs': None}

If I nagivate to http://0.0.0.0:6006, I see a blank white page.
[Stack: OSX, Google Chrome, Python 3, TensorFlow installed via pip]
Try navigating to localhost:6006 instead (equivalent to http://127.0.0.1:6006/).
It works fine for me while http://0.0.0.0:6006 yields no result.
I had a similar issue with TensorBoard 1.4 (no errors on start but black page in browser). In my case it helped to set the host explicitly to 127.0.0.1 with --host
