Reproduction

Importing evaluate fails when kernels v0.15.1 is installed.

It looks like this is caused by a recent change in kernels: specifying either a kernel version or an explicit revision is now required for Hub-backed LayerRepository / FuncRepository entries.

According to the kernels migration guide, pulling kernels from a repository without specifying a version was deprecated in kernels 0.12 and became an error in kernels 0.15.

import evaluate should succeed.
