@christang, can you help me out with this, please. I'm currently facing a NotImplementedError even when I believe to be doing the pickling right. Any advice would be greatly appreciated...

Hi, it seems the issue is still present in _Ranked batch-mode sampling_. ### Reprex (mostly from [Ranked batch-mode sampling documentation](https://modal-python.readthedocs.io/en/latest/content/examples/ranked_batch_mode.html)) ```python import numpy as np import xgboost as xgb from...

Hi!, as you correctly mentioned this should only work for models that can handle missing values such as novel boosting methods (i.e. xgboost). Alternatively, [`nan_euclidean_distances`](https://scikit-learn.org/stable/modules/generated/sklearn.metrics.pairwise.nan_euclidean_distances.html) function could serve to solve...

Another example: ```python # Conditional search spaces langevin = [{'langevin': False}, {'langevin': True, 'diffusion_temperature': hp.uniform('diffusion_temperature', 5000, 15000)}] # Definition of search space search_space = { # ... 'langevin': hp.choice('langevin', langevin),...
