Poetry update, lock and install throws: `Could not parse version constraint: <empty>* #10577
Description
Description
The transformers library has the optax package as a dependency that dependency is written down as "optax ()" in the poetry lock. Deleting and regenerating the solution results into the same state. The initial update passes but there is no followup with that poetry.lock possible.
Workarounds
No workaround found. Waiting with dep update.
