anko-intel opened a new issue #18610: URL: https://github.com/apache/incubator-mxnet/issues/18610
## Description During investigation of #14357 I have found that running_mean and running_var variables are sometimes not yet calculated when converted to NumPy. ### Error Message When runing the python test from https://github.com/apache/incubator-mxnet/issues/14357#issuecomment-644887485 sometimes there is information that consecutive reads of the same variable differes, which means that backward pass is calculated after the first read: `var1 = layer2.running_var.data().asnumpy()` It shouldn't happen as asnumpy() function should force all needed calculations to get running_var values. I such case the test shows a message similar to the one below: ``` seed: 331752807 cpu(0) - DIFF in running_var reads: 0 : [3.9974644 3.9977627 3.997775 ] 2 : [3.9962945 4.0025434 3.9987571] cpu(0) [3.9962945 4.0025434 3.9987571] [10.001289 9.997483 10.002162] gpu(0) [3.9962947 4.0025434 3.9987576] [10.001292 9.997481 10.002162] ``` Verified on master branch 959143696 ## To Reproduce run python test from https://github.com/apache/incubator-mxnet/issues/14357#issuecomment-644887485 ## What have you tried to solve it? I already have the fix. I will put it to github soon. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
