wikier commented on issue #12746: Add env flag to disable MKLDNN cache (MXNET_MKLDNN_CACHE_ENABLED) URL: https://github.com/apache/incubator-mxnet/pull/12746#issuecomment-431495155 Confirmed the new env variable helps to mitigate the memory issue we've seen. Roughly, because it's be very network-dependent, for us going from `MXNET_MKLDNN_CACHE_SIZE=512` to `MXNET_MKLDNN_CACHE_SIZE=128` gives a 55% memory saving for a 7% performance loss.
