Checklist

• Title of this PR is meaningful: e.g. "Adding my_nifty_package", not "updated meta.yaml".
• License file is packaged (see here for an example).
• Source is from official source.
• Package does not vendor other packages. (If a package uses the source of another package, they should be separate packages or the licenses of all packages need to be packaged).
• If static libraries are linked in, the license of the static library is packaged.
• Package does not ship static libraries. If static libraries are needed, follow CFEP-18.
• Build number is 0.
• A tarball (url) rather than a repo (e.g. git_url) is used in your recipe (see here for more details).
• GitHub users listed in the maintainer section have posted a comment confirming they are willing to be listed there.
• When in trouble, please check our knowledge base documentation before pinging a team.

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 (recipes/ultralytics) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipes/ultralytics:

• License is not an SPDX identifier (or a custom LicenseRef) nor an SPDX license expression.

Documentation on acceptable licenses can be found here.

Blocked by getting thop onto conda-forge, which is blocked by Lyken17/pytorch-OpCounter#203.

[abraha2d]

ultralytics 8.0.104 removes the dependency on thop, which unblocks this PR.

Windows build is failing due to missing pytorch packages (see conda-forge/pytorch-cpu-feedstock#32).
Ignoring as this is a noarch package, like #15917 (review)
