问题描述

• 错误信息
  使用x2paddle将onnx模型转换成paddle时，MaxUnpool算子不支持，转换失败。日志如下：
  INFO:root:paddle.version = 2.6.1
  INFO:root:Now translating model from onnx to paddle.
  model ir_version: 6, op version: 11
  Shape inferencing ...
  [WARNING] Incomplete symbolic shape inference
  Shape inferenced.
  Now, onnx2paddle support convert onnx model opset_verison [7, 8, 9, 10, 11, 12, 13, 14, 15], opset_verison of your onnx model is 11.
