I ran into the same issue.  Before installing OpenCV I was on Numpy 1.21.5 in my notebook.  After upgrading to 1.23, the error went away for me.

Can't select cluster when create AutoML experiment

I'm trying to create my experiment using AutoML. I have a running cluster using 12.2 LTS. However,  it isn't available as an option for me. How could I solve it? Thank you

@HAKO411 AutoML needs Databricks Runtime 9.1 ML or above. For time series forecasting, you will need Databricks Runtime 10.0 ML or above. Looks like you are using 12.2 LTS, a non-ML version. Using 12.2 ML LTS should resolve your issue.

@DmytroSokhach  I think it works if you change mongo to mongodb in the options. and use spark.mongodb.read.connection.uri instead of spark.mongodb.input.uri as @silvadev suggested.

 @kashy Looks like the model is not correctly referenced while loading. You should reference the path of the model till ‘model-best’, which is the top-level directory. loaded_model = mlflow.spacy.load_model("</path/to/your/model/>/model-best")
