[jira] [Updated] (FLINK-2278) SparseVector created from Breeze
Sparsevector has wrong size
[ https://issues.apache.org/jira/browse/FLINK-2278?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Christoph Alt updated FLINK-2278:
---------------------------------
Description:
The following code doesn't return true when testing equality of two SparseVectors, one converted from a Breeze SparseVector.
val flinkVector = SparseVector.fromCOO(3, (1, 1.0), (2, 2.0))
val breezeVector = linalg.SparseVector(3)(1 -> 1.0, 2 -> 2.0)
flinkVector.equalsVector(breezeVector.fromBreeze)
The reason is that *fromBreeze* takes the number of non-zero elements *SparseVector.used* as size when creating a SparseVector instead of the dimensionality *SparseVector.length*.
