Hi Shantanu,
at least the pySim developers have no experience with WSL and always use native Linux installations, so we cannot really help.
Maybe some other user has any idea?
In general, you should be using pip to install the dependencies; pip takes care of the recursive dependencies.
From the README à Installation I am unable to install below deps at my WSL environment, can someone please suggest a way to do it please ?
If you would copy+paste the actual error messages you're getting when trying to use pip, we might be able to review it here..
