I think that should work fine for the `pip install scikit-learn`,

E.g., if you run

pip install scikit-learn --upgrade

it would try to upgrade numpy and scipy as well, which may not be
desired. I think the only workaround would be to run

pip install scikit-learn --upgrade --no-deps

unless they changed the behavior recently. I mean, it’s not really a
problem, but many users may not know about the --no-deps flag.

Also - the install will work fine for platforms with wheels, but is
still bad for platforms without - like the Raspberry Pi.
Hm... so these would be ARM wheels? Or Raspberry Pi specific ones?
No, they'd have to be Raspberry Pi specific ones because no-one has
worked out a general ARM-wide specification, as we have for Intel
Linux = manylinux1.

Following up on this thread, I'm trying to write better installation instructions.

What's the best-practice for cases when there are no wheels?
I imagine there's also no conda channel for Raspberry Pi.

So is it the package manager?
