Thank you for the quick reply. The JupyterLab on PowerAI sounds great!

Thank you for reporting this issue. We are fixing it in two ways:
1. Fixing the Apache Toree - R kernel in Jupyter, and
2. Changing the labs to use JupyterLab the new and much improved Jupyter environment for Data Scientists.
Both should be done in the next few days.
