Looks like libMKLDNNPlugin.so is not linked to some numa functions. This error occurred on 2020.1.023 in DevCloud, as well as 2020.2 in a docker environment that was created by the customer. 2019.3.376 worked correctly.

Hi Jing X.
I've just noticed that your error message shows that you were running your job on Intel Devcloud and not Intel Devcloud for Edge.
Please try posting your question in the Intel Devcloud forum: https://software.intel.com/en-us/forums/intel-devcloud
I hope you get your issue resolved soon.
