Refine yt version selection

[astrofrog]

The bug was specifically in 3.3.0 and 3.3.1 but works with >= 3.3.2

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

This needs a re-render with conda-smithy version 1.7.0.

Here's what I've got...

For recipe:

• Selectors are suggested to take a <two spaces>#<one space>[<expression>] form.

Is it just that we need sphinx? We can re-render that for Python 3.6.

[astrofrog]

@jakirkham - no, this was because we bundle numpydoc and this version had small Python 3.6 incompatibilities. The only solution for this release is to remove the sub-packages (which aren't really public API, just used when building the docs) and the next release of Hyperion will support 3.6 properly (I'm removing the bundled numpydoc).

[astrofrog]

@jakirkham - however, this is going to fail because yt for Python 3.6 didn't get uploaded for Linux: conda-forge/yt-feedstock#16 - any ideas on that issue?

Strangely the build for CircleCi here ends with:

without further explanation. But I'm pretty sure it's because yt (runtime dependency) isn't available for Python 3.6 on Linux.

[jakirkham]

You're probably right in assuming yt. ATM conda is not great about explaining unsatisfied dependencies, but looking for dependencies missing Python 3.6 packages is a good first step.

Commented on the aforementioned issue. We can keep that discussion there.

Other thing you can try is skipping Python 3.6 in the interim while things get sorted. Just add skip: true [py==36] to do this. May need to combine using or with other selectors (e.g. Windows).
