sagemaker limitations

[Shaked35]

Describe the feature you'd like
I am using SageMaker hyperopt parameters tuning, and I found some limitations.
There is a limit of 2500 characters in shared_parameters, so I can't pass X columns as features.
The number of categories is limited to 30 as I see it (I'm not sure this is the actual limit). We need more categories.
The number of characters in a categorial element is limited to 256, but we are able to handle long strings.

How would this feature be used? Please describe.
run more hyperparameters with different features

Hi @Shaked35 , While our support team is looking into this issue please note that "you can now run tuning jobs with up to 900 categorical value". More info here: https://aws.amazon.com/about-aws/whats-new/2022/12/amazon-sagemaker-automatic-model-tuning-higher-limits-categorical-hyperparameters/.

To upgrade the SDK to latest, please use:
pip install --upgrade sagemaker

@Shaked35 Just want to expand on comments of @urirosenberg . You could optimize up to 30 categorical parameters, while every categorical parameter can contain up to 30 different values. Thus 900 categorical values in total.

@Shaked35 Does the suggested resolution works for you? Can you confirm?
