Hi! This is the staged-recipes linter and I found some lint.

File-specific lints and/or hints:

• recipes/mat4py/meta.yaml:
  • lints:
    • Feedstock with the same name exists in conda-forge.

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 (recipes/mmpretrain/meta.yaml, recipes/mat4py/meta.yaml) and found some lint.

Here's what I've got...

For recipes/mmpretrain/meta.yaml:

• ❌ requirements: run: grad-cam >= 1.3.7,<1.5.0 should not contain a space between relational operator and the version, i.e. grad-cam >=1.3.7,<1.5.0

For recipes/mmpretrain/meta.yaml:

• ℹ️ Recipes should usually depend on matplotlib-base as opposed to matplotlib so that runtime environments do not require large packages like qt.
• ℹ️ top-level output has some malformed specs:

• In section run: grad-cam >= 1.3.7,<1.5.0 Requirement spec fields should match the syntax name [version [build]]to avoid known issues in conda-build. For example, instead of name =version=build, use name version.* build. There should be no spaces between version operators and versions either: python >= 3.8should bepython >=3.8`.

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