> File "src/ndarray/./../operator/tensor/.././../common/../operator/nn/mkldnn/mkldnn_base-inl.h", line 246 MXNetError: unknown type for MKLDNN :2 If you look at this file: https://github.com/apache/incubator-mxnet/blob/64f737cdd59fe88d2c5b479f25d011c5156b6a8a/src/operator/nn/mkldnn/mkldnn_base-inl.h#L234-L247 You'll see its running dtype checking and doesnt find a case in the switch for value 2. If you go look at what value 2 is: https://github.com/apache/incubator-mxnet/blob/64f737cdd59fe88d2c5b479f25d011c5156b6a8a/3rdparty/mshadow/mshadow/base.h#L351-L354 You'll see that its `kFloat16`. So you're script is somehow using FP16 and MKLDNN doesnt support that type. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
