Step 2: Scroll down to Data Science Workbench.
Step 3(Optional): Toggle the Accelerate Jupyter to assign a GPU to Jupyter. This toggle is optional for regular scripts, it is required for the Jupyter notebooks that involve using models. The tutorial notebooks which require GPUs will state that requirement in the first cell of the notebook. The toggle will be in progress until the GPU is successfully assigned to Jupyter, if there are no available GPUs the request will become queued and catch the next GPU that is freed up.
