I was going through the numpy tutorials and found import roslib; roslib.load_manifest('YOUR_PACKAGE_NAME') in the beginning of the publisher and subscriber code. I never saw them while following the tutorials for publisher and subscriber for ros hydro. What is the need for rosblib.load_manifest?

In large projects, your code might depend on many external packages. A manifest contain meta-information about what your software is doing and how to set it up. The documentation is quite exhaustive on the topic:

Practically speaking, you can very well just "import roslib; import rospy" and your code will still work. You might however want to think of writing a manifest as soon as you start depending on other libraries and want to share you code with other people.
