Won't work, cf below.

A Python package is a filesystem directory with an __init__.py file in 
it. In your above layout, you have two *distinct, unrelated* packages 
both named nutum. The first found in sys.path will shadow the second.

You either need to rename one, or "refactor" your layout to have utils 
and sysinfo under the same root package, ie:

workspace/src/nutum/__init__.py
workspace/src/nutum/utils/__init__.py
workspace/src/nutum/utils/general.py
workspace/src/nutum/utils/elapsed_time.py
workspace/src/nutum/utils/execute_command.py
workspace/src/nutum/utils/size_units.py
workspace/src/nutum/sysinfo/__init__.py
workspace/src/nutum/sysinfo/sysinfo.py
workspace/src/nutum/sysinfo/modules/__init__.py
workspace/src/nutum/sysinfo/modules/base_module.py
workspace/src/nutum/sysinfo/modules/os.py
