you're using a version of onnxruntime built for python 3.6 ,
but it looks like your conda environment is python 3.7
did you build onnxruntime from source? if you want to use python 3.7 , make sure the python lib for 3.7 is in your path. instead it is finding python 3.6 during build.
Try activating your python 3.7 environment prior to building?
(or try running onnxruntime using the python 3.6 that was used to build it rather than in the python 3.7 conda environment)

[verigle]

yes,I build onnxruntime from source used system default python of version 3.6.I will activating your python 3.7 environment prior to building.
Thank you!
