Hello. I’m looking for help running this workflow, please. I would also appreciate any pointers to debugging techniques for this sort of problem.
I can’t get the “ONNX to Tensorflow” node to execute correctly. I’ve tried various versions of Python and Tensorflow and am now at 3.7.9 and 2.10.0. I’m running Windows 10-64 with no GPU.
I get an error on the node which just says “Execute failed: ‘input’”
I see the following in the log:
2022-11-08 19:23:07,367 : INFO : Thread-41 : PythonKernel : ONNX to TensorFlow Network Converter : 0:2 : To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags.
