 The right side of the windows is split into 3 parts: `WHERE` (top left), `WHAT` (bottom left), and `HOW` (right). With `WHERE`, you can assign a machine where you want to run the profiling on. With `WHAT`, you can set the path of the application that you want to profile. To profile a PyTorch script, it is recommended to wrap all manual steps, including activating a Python environment and setting required environment variables, into a bash script, then profile this bash script. In the screenshot above, we wrapped all steps into the `launch.sh` bash script and profile `bash` with the parameter to be `<path_of_launch.sh>`. On the right side `HOW`, you can choose whatever type that you would like to profile. Intel® VTune™ Profiler provides a bunch of profiling types that you can choose from.
