Anirudh Acharya commented on MXNET-212:
---------------------------------------
This issue is not reproducible on Mac with my RStudio installation. But I am
able to reproduce it on one of my EC2 instances.
The only difference in the two installations is the mxnet version -
In Mac I am running
{{other attached packages: [1] mxnet_0.10.1 }}
whereas on the ubuntu installation I am running the latest version -
{{other attached packages: [1] mxnet_1.2.0 }}
The root cause of the problem is the behavior of mxnet's uniform distribution
generator which is internally used for shuffling the {{arrayiter}} object.
On the old code, I get the following
> mx.runif(shape=10, min=0, max=1, ctx=mx.cpu()) [1] 0.04804938 0.65167809
> 0.77450776 0.67896259 0.21799077 0.29066718 0.08128081 0.97726691 0.04218456
> 0.40008616
On the latest mxnet v1.2 I get the following -
> mx.runif(shape=10, min=0, max=1, ctx=mx.cpu()) [1] 1.168184e-35 0.000000e+00
> 0.000000e+00 2.522337e-44 0.000000e+00 [6] 0.000000e+00 1.401298e-45
> 0.000000e+00 6.726233e-44 0.000000e+00
Similar errors exist for the {{mx.rnorm}} too in the latest code.
