[cvsekhar]

Platform & setup MacOS: 10.15.5 docker for desktop (mac): v19.03.8

Describe the bug Tensorboard doesn't get displayed after clicking the send to tensorboard button after running an experiment.

To Reproduce Steps to reproduce the behavior:

1. git clone CIFAR tutorial
2. enable the tensorboard integration by foundations.set_tensorboard_logdir('train_logs')
3. foundations submit scheduler . driver.py
4. after the job is completed click on send to tensorboard a blank page is displayed

Expected behavior tensorboard page should be opened

Screenshots

Additional context / Stacktrace tensorboard rest API port 5000 might not be exposed as both this and scheduler are trying to listen on the same port.
