[CentralOH] Fwd: Pip users: big change coming this month

[Travis Risner]

Hi Folks,

As noted here, big changes are coming to __pip__ this month involving 
the dependency resolver.

-	Pip 20.2 (already out) has new resolver in it.  Add

		--use-feature=2020-resolver

	to use.

-	Pip 20.3 (Probably will be released in January 2021) will use the new 
resolver by default, but a flag is available to use the current 
resolver.

-	Pip 21.0 (Probably will be released in April 2021) will use the new 
resolver only.  The current resolver will no longer be available.

Details and links to more info and a short video are given below.

Changes are coming to pip, Python's package installation tool, in 
October 2020. Please read and share this migration guide: 
https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-resolver-in-20-2-2020 
.

We're working on improving the Python packaging toolchain, foundational 
work that will (in the long run) make the whole Python package 
installation experience way less confusing.

The pip team made a 2-minute video to explain what's up:

We are also doing user experience studies, and want you to sign up if 
you ever do anything with Python (whatever your level of 
skill/experience):

https://mastodon.social/@brainwane/104950044427849411 is a good toot to 
boost, and https://twitter.com/ThePSF/status/1311038036013199363 is a 
good tweet to retweet, if you want to help us get the word out.
