ImportError: No module named progressbar

Tips：
progressbar is a Python library you have to install separately, I don’t think it was required before but with the recent update Jack added download progress text to the GetRegion script, which utilizes the progressbar library. Download it from here: http://code.google.com/p/python-progressbar/downloads/list

Once you unpack it, cd to the extracted directory and run sudo ./setup.py install to install it into python.

or(using pip)
pip install progressbar
