I am trying to create ping_pong file in python . If I use command bazel run //apps/tutorials/ping_pong_python. There is an error

So, I try giving bazel run //apps/tutorials/ping_pong_python: I have two questions related to this:

  1. how can I run simultaneously file
  2. And by running by specifying only file, I still get an error
  3. After getting error in point 2 , I tried to set interpreter #!usr/bin/python, so it gives error

Can someone please help me with this error, as there are no proper tutorials for python provided it is really difficult working with python in Isaac SDK?
