Relative Path issue in shell script

I am having trouble creating path reference in shell scripts.

I have 1 parent folder, which has 2 child folders.

Directory Structure =>

Parent
    |
    -- Child1 (contains shell script start)
    |
    -- Child2 (contains python files)

Now inside Child1, I have start.sh

#!/usr/bin/env bash
/usr/bin/python ../Child2/code1.py

Problem :

When I cd into Child1 and run the start.sh, it works perfectly.

But when I run start.sh from anyother directory (say /home/), the relative path reference in the shell script complains. It says No file found, and this is because it is using /home/ and using that as relative path. I have tested this by doing an echo $pwd

I have tried `$pwd' & '$cwd'. It does not help.

My aim is to have this shell script to work from anydirectory. How can I achieve this?

Looking forward to some help here. I would be happy to add more information if needed.

why not pass a full path? – Padraic Cunningham Oct 02 '15 at 18:08
can you clarify what you mean by "it complains"? What exactly is the error you are getting, and exactly what command are you executing? – Greg Oct 02 '15 at 18:09
The current working directory (which is what relative paths are considered relative *to*) is independent of where the file resides. – chepner Oct 02 '15 at 18:11
@Greg - I have added the error explanation. – sudhishkr Oct 02 '15 at 18:13
@PadraicCunningham - the parent folders location is not decided, and can be kept anywhere. Using the fullpath will not be suitable for my usecase. – sudhishkr Oct 02 '15 at 18:14
@chepner - thanks for pointing this duplicate. It had the solution `pushd 'dirname $0' > /dev/null \ SCRIPTPATH='pwd' \ popd > /dev/null` – sudhishkr Oct 02 '15 at 19:44
