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.

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

For recipe:

• It looks like the 'tensorflow-base' output doesn't have any tests.

Is there a reason why this can t be built in an entirely different feedstock?

The compile timw for the tensorflow feedstock is already too long.

@hmaarrfk thx for the quick feedback and sorry confusion.

I miss interpreting #276 (comment)
