   >ACL not supporting training specific operators makes sense, but it should ideally default to OneDNN's reference kernels
   
   It should fallback to reference as per this implementation list https://github.com/oneapi-src/oneDNN/blob/b2cd3a8e50a715f9326a35f4c503bd11e60235a5/src/cpu/cpu_deconvolution_list.cpp#L48. Since there is no deconvolution operator implemented in ACL here.
   
   For convolution, you can see the implementations here https://github.com/oneapi-src/oneDNN/blob/b2cd3a8e50a715f9326a35f4c503bd11e60235a5/src/cpu/cpu_convolution_list.cpp#L105 guarded by CPU_INSTANCE_AARCH64_ACL.
   and within the convolution we have checks to make sure FWD phases are enabled https://github.com/oneapi-src/oneDNN/blob/b2cd3a8e50a715f9326a35f4c503bd11e60235a5/src/cpu/aarch64/acl_convolution_utils.cpp#L47
   
   Could you please check if MxNET implements deconvolution via oneDNN's deconvolution operator?
