class_docstr: Wrap around InferenceSession in onnxruntime, since it cannot be pickled.
  See https://github.com/microsoft/onnxruntime/issues/10097
code: def __init__(self, onnx_bytes):
      import onnxruntime as ort
  
      self.sess = ort.InferenceSession(
          onnx_bytes.SerializeToString(),
          providers=["CPUExecutionProvider"],
      )
  
imports: import os
  import numpy
label_desc: Use image node_id 1 to create a new InferenceSessionWrapper object  with example: obj = InferenceSessionWrapper(onnx_bytes)
