universewill edited a comment on issue #12952: a very interesting problem URL: https://github.com/apache/incubator-mxnet/issues/12952#issuecomment-432517785 I just don't understand why the accuracy is decreasing during each epoch. You can see the accuracy is decreasing for batches. I think it has nothing to do with mxnet version? ``` INFO:root:Epoch[9] Batch [4] Speed: 137.92 samples/sec accuracy=0.225000 INFO:root:Epoch[9] Batch [8] Speed: 137.97 samples/sec accuracy=0.173828 INFO:root:Epoch[9] Batch [12] Speed: 137.87 samples/sec accuracy=0.099609 INFO:root:Epoch[9] Batch [16] Speed: 137.93 samples/sec accuracy=0.082031 INFO:root:Epoch[9] Batch [20] Speed: 137.42 samples/sec accuracy=0.058594 INFO:root:Epoch[9] Batch [24] Speed: 138.03 samples/sec accuracy=0.041016 INFO:root:Epoch[9] Batch [28] Speed: 137.75 samples/sec accuracy=0.033203 INFO:root:Epoch[9] Train-accuracy=0.031250 INFO:root:Epoch[9] Time cost=27.864 ``` My minxes version is 1.3.0 @wkcn
