Revision 824ac86620572285b86dd09529f8869ef36883ad authored by Peter Hawkins on 03 April 2020, 19:39:56 UTC, committed by GitHub on 03 April 2020, 19:39:56 UTC
* Reimplement np.cumsum and np.cumprod in terms of a parallel prefix scan. Unlike the existing implementation based on lax.reduce_window, this implementation is O(n log n) instead of O(n^2) and is arbitrarily differentiable. Fixes #1212, #2418, #2542. May help with issue #2380. * Relax gradient test tolerance.
