fhieber commented on issue #13862: [Bug] unravel_index no longer works with magic '-1' in shape parameter after 1.3.1 URL: https://github.com/apache/incubator-mxnet/issues/13862#issuecomment-457954221 Hoping to get some activity on this. I bisected the nightly builds to figure out, when this bug was introduced. - `mxnet==1.3.1b20181005` is fine - `mxnet==1.3.1b20181010` contains the bug Assuming that builds are roughly reflecting merge dates of PRs, the bug must be introduced some time between October 5th and October 10th. There is no code change in the ravel.* files or the unravel_index op itself since its addition, so I would guess that some other type of change caused this unwanted regression; maybe unravel_index uses some outdated interface? The only commits where I could guess that they could have some effect on this: - https://github.com/apache/incubator-mxnet/commit/443ded4f8ab455a4c4ec0b9d431564b8ccc785ea - https://github.com/apache/incubator-mxnet/commit/5314cf4742767319ce356bd5154c6885380e0d5c - https://github.com/apache/incubator-mxnet/commit/f9f74169bb05f85d85dec5991aa5fc9050dec9f6 - https://github.com/apache/incubator-mxnet/commit/ebe6ea8be97506dba7d00b5a25da58433e38caae - https://github.com/apache/incubator-mxnet/commit/bcd24f85457821f9c0ce17d60e545a252a87a5ae#diff-58bd15446e511bc1b965256ed89ed624 - https://github.com/apache/incubator-mxnet/commit/e1fe7b14f4c31c35f77c9ee3b701a59db86c38c0 Unfortunately I don't have a way to bisect commits directly through source compilation right now. I would appreciate some support on this. Thanks!
