   @Caenorst  Looks like the TRTCreateState function in 
[src/operator/subgraph/tensorrt/tensorrt.cc](https://github.com/apache/incubator-mxnet/blob/56e79853ad5cf98baf84454eb595c7658bef6ee6/src/operator/subgraph/tensorrt/tensorrt.cc#L263)
 file not passing the ctx to the TRT. 
   Add 
   ```c++
   CUDA_CALL(cudaSetDevice(ctx.dev_id));
   ```
   will fix this issue, but not sure it is a good fix.
