Hi
I executed ./flink-1.11.1/bin/flink run -c com.datacolin.Job ./flink-onnx-pytorch/target/scala-2.11/flink-onnx-pytorch-assembly-0.0.1.jar appeared as follows error：

It sounds like the ai.onnxruntime.OrtEnvironment class is not found during runtime. It should be packaged in the JAR by sbt. Does your JAR contain it?

Here is what I see when I look for the class in the JAR:

$ jar tf flink-onnx-pytorch-assembly-0.0.1.jar | grep OrtEnvironment.class
ai/onnxruntime/OrtEnvironment.class
