According to @mcara, `/root/repo/notebooks/DrizzlePac/align_multiple_visits/tweakreg.log` should give more ideas on what happened. @obviousrebel , how do I get that artifact out of CircleCI?

Good point, Mihai! https://stackoverflow.com/questions/6773584/how-is-pythons-glob-glob-ordered

Bingo, Mihai wins: `reference image 'j9irw5kaq_flc.fits'`

I am trying to fix the TweakReg thingy over at #78.

@eteq , if you rebase, the DrizzlePac error will not bother this PR anymore.

This probably need a rebase and see if CI would still pass.

I have no idea what this download is doing, so I'll not be reviewing. You should ping someone from MAST. Maybe @jaymedina

@eslavich , are you familiar with CRDS error codes? Thanks! cc @samanthalh

@samanthalh ?

Thanks! Probably want to update the `requirements.txt` to bump the min version too.
