Sorry the Dato Launcher 2.0 is behaving this way for you. We are looking into it and can push a fix automatically without uninstalling.
Can you please share what OS and version you are using? Is the issue only after upgrade of did anyone experience with a new install of Dato Launcher 2.0?
Please try this work-around.
After you have installed Dato Launcher 2.0, you can use command line to start ipython or ipython notebook. The Dato Launcher 2.0 installs the necessary packages, including GraphLab Create, in a conda environment called 'dato-env'.
1-open a new terminal (without using the Dato Launcher)
2-execute the following in shell to activate the conda environment where Dato Launcher installs GraphLab Create and Python dependencies.
source activate dato-env
At this point, you can use GraphLab Create in terminal using ipython or in an IPython Notebook.
ipython in terminal, then in ipython execute
IPython Notebook: execute
ipython notebook in terminal, then in a notebook cell execute 'import graphlab'. IPython Notebook sets the root directory in the UI to the working directory from which it was initiated. You can navigate to any directory on your system before executing 'ipython notebook'.
Let me know if this works for you. Tim
