pySpark: Save ML Model

Question

Can someone please give an example of how you would save a ML model in pySpark?

For

ml.classification.LogisticRegressionModel

I try to use the following:

model.save("path")

but it does not seem to work.

If I understand your question correctly, your method signature is incorrect.

According to the docs you also need to pass in your spark context.
