Bug Report

Error merging shape info for output.

Error message

[W:onnxruntime:, graph.cc:109 MergeShapeInfo] Error merging shape info for output. 'onnx::Add_15' source:{5,50,1} target:{1,5,50,1}. Falling back to lenient merge.

To reproduce

1. Download model here shape_model.zip

2. Run the test script

import onnxruntime as rt

sess_options = rt.SessionOptions()

# Set graph optimization level
sess_options.graph_optimization_level = rt.GraphOptimizationLevel.ORT_ENABLE_EXTENDED

# To enable model serialization after graph optimization set this
sess_options.optimized_model_filepath = "opt_model.onnx"

session = rt.InferenceSession("model.onnx", sess_options)

Notice:

1. sess_options.graph_optimization_level = rt.GraphOptimizationLevel.ORT_ENABLE_EXTENDED

   → error

2. sess_options.graph_optimization_level = rt.GraphOptimizationLevel.ORT_ENABLE_BASIC

   →run well
