Error from Hyperdash server: invalid_request.invalid_json

[dtmoodie]

I've recently started receiving the above error message. Any input would be appreciated, I have a training session that starts and appears on the dashboard for a little bit and then is listed as disconnected.

Could you run pip freeze in your python environment and post the output here?
