"Assertion failed: Connection reset by peer": what could I do about it?

Thanks jason!
I look for a solution since several months now!
I know very nothing about networking, TCP, …
If I just could find any trick that would allow a Jupyer notebook to work during a full night, I would be happy.
If disabling some process, or unstalling an application would do it, I woul be happy.
In the meanwhile I organize myself to run Python from the Anaconda prompt during the night.
But this is not very convenient for experimental ML tests.
Thanks again
Michel
