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/meta.yaml) and found it was in an excellent condition.

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

For recipe/meta.yaml:

• ℹ️ noarch: python recipes should usually follow the syntax in our documentation for specifying the Python version.
  • For the test.requires section of <output 0 output, you should usually use the pin python {{ python_min }} for the python entry.
  • For the host section of <output 1 output, you should usually use the pin python {{ python_min }} for the python entry.
  • For the run section of <output 1 output, you should usually use the pin python >={{ python_min }} for the python entry.
  • For the test.requires section of <output 1 output, you should usually use the pin python {{ python_min }} for the python entry.
  • If the package requires a newer Python version than the currently supported minimum version on conda-forge, you can override the python_min variable by adding a Jinja2 set statement at the top of your recipe (or using an equivalent context variable for v1 recipes).

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

I wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found some lint.

Here's what I've got...

For recipe/meta.yaml:

• ❌ noarch packages can't have selectors. If the selectors are necessary, please remove noarch: python, or selector on line 95:
  - pyqt # [build_variant == "pyqt"]

For recipe/meta.yaml:

• ℹ️ The recipe is not parsable by parser conda-souschef (grayskull). This parser is not currently used by conda-forge, but may be in the future. We are collecting information to see which recipes are compatible with grayskull.
