Re: [firedrake] firedrake build failure.

Dear Barry, Satish, Joe, it indeed looks like tensorflow (which is an optional dependency of pyadjoint) is not compatible with python 3.7 (which is what you both have), hence there are no wheels available and pip doesn't install it. Unfortunately, this failure is occurring because we unconditionally install all of the (potentially optional) requirements of pyadjoint. Let us think about how to fix this problem at our end. For now, as Joe says, you can run firedrake-install without the --pyadjoint flag. Hopefully by the time you need pyadjoint for the tutorial we will have a fix deployed via firedrake-update. Cheers, Lawrence
