zheng-da opened a new issue #11448: fail to fall back when sparse arrays are passed to MKLDNN-enabled operators. URL: https://github.com/apache/incubator-mxnet/issues/11448 Currently, the MKLDNN-enabled operators, such as convolution and pooling, can't handle sparse arrays correctly. The reason is that the storage inference of these operators doesn't return the right dispatch mode. The MKLDNN-enabled operators include: - [ ] Activation BatchNorm Concat Convolution Deconvolution Copy FullyConnected LRN Pooling Softmax Sum Flatten
