The CIs are failing. You need to check the reason. Be aware that you will most probably need to edit the test file to remove some of the test that are covered now by the common test enabled by the parameter validation framework.

Thanks for the PR @kasmith11. One of the reason you had failing tests was because the parameter description of kernel in the docstring was incorrect. It also accepts a callable. I pushed a fix for that, and also fixed the bounds of a couple of constraints. I also removed the outdated validation tests instead of commenting them. Should be good now.
