Tensorboard get blank page
The logdir you're pointing tensorboard to probably does not exist (tensorboard does not throw an error in that case). Did you mean tensorboard --logdir=./logs/?
This may come late, but hopefully it will help someone else. If your browser does not accept cookies, you will run into this issue. Make sure you allow cookies for the Tensorboard page you are trying to access.
It may happen to many reason, when I face this problem, I add port number and check the path :
tensorboard --logdir=run1:/tmp/tensorflow/ --port 6006
