• The model includes unsupported node by cvtool
  Run the following command.

  Code Block
  $ graph_surgery.py onnx -m (model name before modification) -o (model name after modification) -t CVFlow

  Please refer here for the list of supported node.
  
  You can check if the model includes unsupported node, by using onnx_print_graph_summary.py in cvtool.

  Code Block
  $ onnx_print_graph_summary.py -p (model name)

• Input of the model has variable value

  

  Replace with fixed value by the following command.

  Code Block
  $ graph_surgery.py onnx -m (model name before modification) -o (model name after modification) -isrc "i:input|is:1,3,960,960" -t SetIOShapes

• Input shape of the model is NHWC, and transposed to NCHW first

  

  Separate from the beginning of the model to “Tranpose” node.
  

  Code Block
  $ graph_surgery.py onnx -m (model name before modification) -o (model name after modification) -isrc "i:(output name of Transpose node)|is:1,3,224,224" -t CutGraph

• Unsupported character ( : |　;　,　‘ ) is included in OUT_LAYER
  Rename the node by the following command.

  Code Block
  $ graph_surgery.py onnx -m (model name before modification) -o (model name after modification) -t "RenameTensors(original_name=new_name)"

  If multiple nodes are specified, please separate those by ",".

  Code Block
  -t "RenameTensors(node::1=node1,node::2=node2)"

• The model has nodes of rank > 4
  Conversion may not be possible due to SoC constraints.
  
  You can check if the model has such nodes, by using onnx_print_graph_summary.py. The following message will be output when the nodes are found.

  Code Block

  $ onnx_print_graph_summary.py -p (model name) INFO: 08/29/2024 03:22:40.725761 onnx_print_graph_summary.py:384 [PrintGraphSummary] Unsupported tensors with rank > 4 (3): INFO: 08/29/2024 03:22:40.725837 onnx_print_graph_summary.py:386 [PrintGraphSummary] -> 'output' [1 x 3 x 52 x 52 x 85] INFO: 08/29/2024 03:22:40.725909 onnx_print_graph_summary.py:386 [PrintGraphSummary] -> '1026' [1 x 3 x 26 x 26 x 85] INFO: 08/29/2024 03:22:40.725993 onnx_print_graph_summary.py:386 [PrintGraphSummary] -> '1046' [1 x 3 x 13 x 13 x 85]

  Please modify the model in one of the following ways.
  ・Modify the nodes before exporting to onnx.
  ・Separate the back of the node from the model.

  Code Block
  $ graph_surgery.py onnx -m (model name before modification) -o (model name after modification) -on (node name before the node of rank > 4) -t CutGraph

  
  ・Replace the node with that of rank <= 4.

  Code Block
  $ graph_surgery.py onnx -m (model name before modification) -o (model name after modification) -t ReplaceSubgraph
