Not sure this is the right forum to discuss but I have a question on using the initial parameter for hyperopt documented at:
https://docs.ray.io/en/latest/tune/examples/hyperopt_example.html
If a parameter is a list, the search will crash with error "“GarbageCollected”, e.g.
initial_params = [{"a": [1, 2], "b": [1, 2, 3]},]
It works fine when the initial parameter contains only single value, e.g.
initial_params = [{"a": 1, "b": 1},]
I can post a short code to reproduce this if necessary
