Expected Behavior

Running sanity tests (Travis build) should pass for all YDK supported platforms.

Current Behavior

Sanity Travis tests on ydk-gen and ydk-py succeed for Linux platform, but fail for Mac OS.
The sanity Travis tests succeed for ydk-cpp and ydk-go for all platforms.

Steps to Reproduce

Start Travis test on ydk-gen and/or ydk-py to see failure of the tests.
The tests also fail when repository is cloned on Mac platform.
