I have followed the procedure given in How to use valgrind with python? for checking memory leaks in my python code.
I have my python source under the path
from concurrent.futures.process import ProcessPoolExecutor
ImportError: No module named concurrent.futures.process
If you're using Python 2.7 you must install this module :
pip install futures
Futures feature has never included in Python 2.x core. However, it's present in Python 3.x since Python 3.2.
