## Description MXNet array indexing will only match numpy memory sharing in a few cases. ## To Reproduce Simple slice; mxnet matches numpy ``` python a = mx.np.ones((10,)) b = a[:5] a[:] = 0 print(a, b) # [0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [0. 0. 0. 0. 0.] ``` Slice with step; mxnet diverges ``` python a = mx.np.ones((10,)) b = a[:5:2] a[:] = 0 print(a, b) # [0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [1. 1. 1.] ``` as numpy still shares memory between the arrays: ``` python a = np.ones((10,)) b = a[:5:2] a[:] = 0 print(a, b) # [0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [0. 0. 0.] ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
