Sparse tensor: CSR conversion assigns entries using value offsets as row numbers · case 05
CSR conversion assigns entries using value offsets as row numbers.
Case contract
Convert valid CSR storage to row-major COO [row,column,value] entries.
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 |
|---|---|---|---|
| empty row | [[0, 2, 5], [1, 0, 6], [2, 1, 7]] | [[0, 2, 5], [2, 0, 6], [2, 1, 7]] | Failed |
