ModuleNotFoundError: No module named 'ray.tune.suggest'

Question

I have installed ray, and I am trying to import

from ray.tune.suggest.hyperopt import HyperOptSearch

but I keep receiving

ModuleNotFoundError: No module named 'ray.tune.suggest'

I checked the documentation but didn`t see anything that can give me a clue about this problem.

Any idea?

A quick Google search gave me https://maxpumperla.com/learning_ray/ch_05_tune/ , which suggests adding this to the beginning of your notebook (and running it):

! pip install "ray[tune]==2.2.0"
! pip install "hyperopt==0.2.7"
! pip install "bayesian-optimization==1.3.1"
! pip install "tensorflow>=2.9.0"

You can try these lines or something similar. You may want to ask the author of https://youtube.com/watch?v=YBJd8BQWK8Q on what ! pip install command they use.
