nice! the build conda pkg check is hanging because it won't run but is required right? Will need an intervention to change that 😄

[freddyaboulton]

@jeremyliweishih Yes! I'm hoping @dsherry can help on Monday!

Nice!

[dsherry]

@freddyaboulton ok, seems cool to me!

We may end up wanting to keep this enabled on merges to main just to have continuous proof things are alright. I am fine with removing it for now though.

I removed this job from our branch protections, so you are clear to merge.

[freddyaboulton]

@dsherry Modified the yaml so that it will run on merges to main!
