Shapley computation trought Spark

Hello everyone,
in Shapley computation using UDF we encouter memory issues or very long processing time.
Tryng to redefine the process with pySpark recipe we use the method "GBTClassificationModel.load" from the library "from pyspark.ml.classification import GBTClassificationModel" in custom code.
Unfortunately the load method takes too long (more than 4h) to upload the model.
Do you know how to speed up the process or work directly with the model without loading it?
I leave attached the code snippet

Hi, can you please paste the code in a Code Block (look for the </> icon) so it can be copy/pasted? Thanks
