eric-haibin-lin commented on issue #11124: make slice operator 20x faster on GPU URL: https://github.com/apache/incubator-mxnet/pull/11124#issuecomment-419574397 @BiranLi i'm using this test code: ``` import mxnet as mx import time a = mx.nd.ones((512, 8192), ctx=mx.gpu()) for i in range(10): b = a.slice(begin=(None, 4), end=(None, None)) mx.nd.waitall() t0 = time.time() for i in range(1000): b = a.slice(begin=(None, 4), end=(None, None)) mx.nd.waitall() t1 = time.time() print(t1 - t0) ``` What did you use? Are you on slack?
