   Thanks for reporting this. the error message `Unsupported MKLDNN dimensions: 3` is from
   ```
   mkldnn_memory_format_t GetDefaultFormat(int num_dims) {
     switch (num_dims) {
       case 1: return mkldnn_x;
       case 2: return mkldnn_nc;
       case 3: return mkldnn_ncw;
       case 4: return mkldnn_nchw;
       case 5: return mkldnn_goihw;
       default:
         LOG(FATAL) << "Unsupported MKLDNN dimensions: " << num_dims;
         return mkldnn_format_undef;
     }
   }
   ```
   If num_dims is 3, `mkldnn_ncw` should be returned. This is already fixed in master about a month ago. Can you have a try on the latest nightly build? @xinyu-intel Does this fix merge into 1.3.1?
