While running a job in google cloud ML, I have included few dependent packages in setup.py . While running the job, it gives the error that cryptography is not able to build_wheel. Cryptogrpahy could be a dependent package for one of the packages that i am trying to install. Please help !!!

You can configure your setup.py script to run arbitrary commands as part of installing your code; see this SO Question.

To clarify Jeremy's answer a bit, a few lines after the screen shot, I see the following in the logs:
"Package libffi was not found in the pkg-config search path."
This SO answer indicates that the following needs to be run (based on cryptography's documentation)
apt-get install build-essential libssl-dev libffi-dev python-dev
Jeremy's answer contains a link to an example setup.py that runs apt-get install for python-tk. You should be able to follow the same approach with the following modification:
self.RunCustomCommand(
['apt-get', 'install', '-y', 'build-essential',
'libssl-dev', 'libffi-dev', 'python-dev'])

Can you try running the apt-get command on your system or in a Docker container to see whether the supplied apt-get command works correctly? My guess the install process is trying to compile and build something and its failing. – Jeremy Lewi Apr 17 '17 at 12:41

I was able to reproduce it and it was because of the 'sudo' command, which I've removed from my post above. After removing sudo, things work correctly for me. – rhaertel80 Apr 17 '17 at 14:35
