Problem

When running the example code for ray.tune integration in the readme,
The script successfully exectures from ray import tune but fails on the line resources_per_trial=ray_params.get_tune_resources())
I think this is due to the TUNE_INSTALLED global set in the xgboost_ray/tune.py file.

It seems that line 15 in that script (from ray.tune import is_session_enabled) is failing due to ray.tune not having that attribute.

Steps to reproduce:

in this section of the readme

Came across the same issue and reinstall Ray didn't help.
