well, I understand the math (having two vectors) but the python
MatrixFactorizationModel object seems to be just a wrapper around java class so
not sure how to extract the two RDDs?thx,Antony.

Yep. the matrix model had two RDD vectors representing the decomposed matrix.
You can save these to disk and re use them.

Hi,
when getting the model out of ALS.train it would be beneficial to store it (to
disk) so the model can be reused later for any following predictions. I am
using pyspark and I had no luck pickling it either using standard pickle module
or even dill.
does anyone have a solution for this (note it is pyspark)?
thank you,Antony.
