This is caused by a bug recently introduced into pydfu.py when run under Python 2.7. I just subitted a PR:
https://github.com/micropython/micropython/pull/4384
The simplest way to fix this until that PR lands is to edit the tools/pydfu.py file and make the same one-line change. Around line 88 change bytes to bytearray:

Hi Dave,
Thanks for the quick reply there!!
I don't see any such thing in line number 88. This is in "pydfu.py""

I have both Python2.7.10 as well as python 3.7.2rc1 installed in my mac book. Would this be impacting the build?
If so , should I uninstall the older version?
Thanks in advance!!

You must be looking at an old version. This is the line (already fixed) from the latest master:
