mxnet.base.MXNetError: NaiveEngine only support synchronize Push so far

[chengdazhi]

Hi, I can see that you are using mxnet 1.0.0. In our readme, however, it is suggested to use the official 1.1.0 version, or the newest 1.2.0(no guarantees).
If using a different version of mxnet causes too much trouble for you, I suggest that you do not use NaiveEngine, as we have never tested on this EngineType before. Maybe you can try to use the default MXNET_ENGINE_TYPE: ThreadedEnginePerDevice.

After changing to the default MXNET_ENGINE_TYPE, or upgrading to mxnet 1.2.0, it works well now.
Thank you.

After upgrading to mxnet 1.2.0, this error appears sometimes again when setting MXNET_ENGINE_TYPE to NaiveEngine.

Besides, it raised the following error occasionally:

mxnet.base.MXNetError: [12:01:59] src/operator/nn/./cudnn/cudnn_softmax_activation-inl.h:154: Check failed: e == CUDNN_STATUS_SUCCESS (3 vs. 0) cuDNN: CUDNN_STATUS_BAD_PARAM

But it sometimes work well again if I rerun the program. It seems very weird.
Could you give me some help? Thank you. @chengdazhi

Hi, it has also been found that mxnet 1.2.0 installed by pip has this error. I suggest you build it from source or install 1.1.0.

Again, I don't see why you need NaiveEngine, we have never tested our code on NaiveEngine bofore.

I have downgraded to mxnet 1.1.0 and deleted NaiveEngine, now it works well.
Thank you.
