Is there anyway I can start tensorboard programaly

[jyhong836]

I want to start a tensorboard like jupyter-tensorboard do when I am using jupyter-ipython. Is there any way I do that.
For example:

logdir = 'a/bb/ccc' #relative to root dir.
start_tensorboard(logdir)

I try to send a request, but it doesn't work, though.

data = {'logdir':  'a/bb/ccc'}
content_type = {"Content-Type": "application/json"}
req = requests.Request('POST', 'http://localhost:8888/api/tensorboard', 
                             data=data, headers=content_type)
r = session.send(req.prepare())
print(r.text)
# output:
# {"message": "Forbidden", "reason": null}
