Hi,
I had a sparse matrix and I wanted to add the value of a particular row
which is identified by a particular number.
from pyspark.mllib.linalg.distributed import CoordinateMatrix, MatrixEntry
mat =
CoordinateMatrix(all_scores_df.select('ID_1','ID_2','value').rdd.map(lambda
row: MatrixEntry(*row)))
This gives me the number or rows and columns. But I am not able to extract
the values and it always reports back the error:
AttributeError: 'NoneType' object has no attribute 'setCallSite'
Thanks and Regards,
Gourav Sengupta
