Gpt2-10 model from onnx-models: Graph must be in single static assignment (SSA) form #67

Open sergei-mironov opened 4 years ago

sergei-mironov commented 4 years ago

Here is the error I found after applying TASO (commit dce8c4d967f ) to the GPT-2 model of onnx-models.

Traceback (most recent call last):
  File "taso/examples/test_onnx.py", line 19, in <module>
    onnx.checker.check_model(onnx_model)
  File "/opt/conda/lib/python3.8/site-packages/onnx/checker.py", line 91, in check_model
    C.check_model(model.SerializeToString())
onnx.onnx_cpp2py_export.checker.ValidationError: Graph must be in single static assignment (SSA) form, however 'data' has been used as graph input names multiple times.

This may be due to ONNX version problem. You can skip onnx.checker.check_model(onnx_model) and just export exported model can be visualized by Netron also
