Hi,

I would like to know how to write a Matrix or Vector (Dense/Sparse) to file?

Thanks in advance!
Best regards,
Lydia

Hi Lydia,

`FlinkMLTools.persist` method is used to save ML models and can be used to save Matrix and Vector object. Note that the method uses TypeSerializerOutputFormat which is binary output format.
