[GitHub] [incubator-mxnet] gyshi opened a new issue #15478: compute in GPU ,
astype('int32') overflow problem
gyshi opened a new issue #15478: compute in GPU , astype('int32') overflow problem
URL: https://github.com/apache/incubator-mxnet/issues/15478
this is in cpu
>>> np.logspace(12.22,3.44,4, base = 33,).astype('int32')
array([-2147483648, -2147483648, -2147483648, 167373], dtype=int32)
this in gpu.
>>> np.logspace(12.22,3.44,4, base = 33,ctx=npx.gpu(0)).astype('int32')
array([2147483647, 2147483647, 2147483647, 167373], dtype=int32, ctx=gpu(0))
>>> (-np.logspace(12.22,3.44,4, base = 33,ctx=npx.gpu(0))).astype('int32')
array([-2147483648, -2147483648, -2147483648, -167373], dtype=int32, ctx=gpu(0))
the result is difference in cpu and gpu computation.
