there’s another interface for Python users: CmdStanPy

for the new MacBook chips - M1, etc, the condo install might also be problematic; installation via pip works just fine: Installation — CmdStanPy 1.2.2 documentation

example notebooks here: CmdStanPy Examples — CmdStanPy 1.2.2 documentation

  1. do i need to install httpstan by cloning the repo or it will work without it also?
    1.1) if yes then all the code do I have to write inside httpstan folder or any other directory?
    1.2) if httpstan require than what should be the location of directory
  2. as I am running on Jupyter note book , which are the packages I need to install?
  3. if I have previously written code in pystan2 than will it work or I need to change the syntex
  4. import stan

what change do in this code to run in mac m1
