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) and found some lint.

Here's what I've got...

For recipe:

• The recipe must have some tests.
• When defining a source/url please add a sha256, sha1 or md5 checksum (sha256 preferably).
• requirements: host: smesh==9.9 must contain a space between the name and the pin, i.e. smesh ==9.9

For recipe:

• Recipes should usually depend on matplotlib-base as opposed to matplotlib so that runtime environments do not require large packages like qt.
