Getting warnings like "Parameter [...] is not of type string"

[samuell]

When running sciluigi workflows, or the tests, with a Luigi version later thatn 2.0.1, we get warnings similar to this:

[samuel sciluigi]$ ./test/run_tests.sh 
NOTICE: this script might not work properly you have CDPATH set to something that contains a folder named 'test'
No handlers could be found for logger "luigi-interface"
/home/samuel/opt/miniconda2/lib/python2.7/site-packages/luigi/parameter.py:259: UserWarning: Parameter NonStringParamWF(instance_name=nonstring_param_wf) is not of type string.

Is there an easy way to silence these warnings if there isn't a fix for it yet?

Hi @apra93 and others. This one is now fixed in Version 0.9.7 (also pushed to PyPI).
