FA-100534 / Sparse tensor canonicalization / Member archive
Sparse tensor: negative COO coordinates are accepted as Python indices · case 04
negative COO coordinates are accepted as Python indices.
Case contract
Return only entries whose row and column satisfy 0<=row<rows and 0<=column<cols.
Why this case matters
A small offline sparse-array operation has explicit coordinate and storage semantics.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| negative row | [[-1, 0, 4], [0, 0, 5]] | [[0, 0, 5]] | Failed |
