SageMath 7.6 Deprecation Warning

[Michael Shea]

I am new to Jupyter and have been have finally been able to install and run the SageMath Kernel, however I am getting an annoying warning on cell execution that I think is slowing down execution. 

I am current running Arch Linux as a VMware guest on windows 10. I installed Jupyter with Anaconnda 3.  I have installed and registered the python 2 kernel in Jupyter. 

I installed sagemath-kernel via pacman and successfully registered it via jupyter-kernelspec. 

Now, whenever I execute a Sage

/usr/lib/python2.7/json/encoder.py:207: DeprecationWarning: Interpreting naive datetime as local 2017-06-03 22:23:23.879862. Please add timezone info to timestamps.
  chunks = self.iterencode(o, _one_shot=True)

Any suggestions.

I believe this has been fixed if you upgrade jupyter_client.

I have the latest version, 5.0.1.  Any other ideas?

Hum, if you can try to turn warnings into errors:

https://docs.python.org/3/library/warnings.html

Then we can try to see the stack trace and figure where this is coming from.
