KeyError: 'input.1' (when compiling ONNX model)

Troubleshooting
#1

Hi everyone,

So I’m trying to compile my ONNX Pytorch model, the first one works but the second model gives “KeyError: ‘input.1’” as error, even though that’s the input together with “1”.

Here is the piece of code:

shape_dict_matrix = { ‘input.1’: (1,256,64,64),‘1’: (1,256,64,83) }

mod_matrix, params_matrix = relay.frontend.from_onnx(matrix_model, shape_dict_matrix)

with relay.build_config(opt_level=0):

matrix_executor = relay.build_module.create_executor('graph', mod_matrix, tvm.gpu(0), target)

dtype = ‘float32’

matrix_output = matrix_executor.evaluate()(tvm.nd.array(vgg_output.astype(dtype)), **params_matrix).asnumpy()

And here’s the full error:

  File "tvm_from_onnx.py", line 99, in <module>
    matrix_output = matrix_executor.evaluate()(tvm.nd.array(vgg_output.astype(dtype)), **params_matrix).asnumpy()

  File "C:\Users\Alexa\AppData\Roaming\Python\Python37\site-packages\tvm-0.6.0-py3.7-win-amd64.egg\tvm\relay\build_module.py", line 333, in _graph_wrapper
    args = self._convert_args(self.mod["main"], args, kwargs)

  File "C:\Users\Alexa\AppData\Roaming\Python\Python37\site-packages\tvm-0.6.0-py3.7-win-amd64.egg\tvm\relay\backend\interpreter.py", line 194, in _convert_args
    cargs.append(kwargs[name])

KeyError: 'input.1'

I did use this pull request https://github.com/apache/incubator-tvm/pull/4536#issuecomment-570700571 to make the Resize op work.

Here are the model properties:

would be great if you can dig a bit further, e.g. provide a few traces, print out the keys at the error point and have a script that can reproduce the error

#4

Sure, here are my models with the script: https://github.com/Aeroxander/tvmexample

I use ONNX 1.6 together with https://github.com/apache/incubator-tvm/pull/4536 to make the Resize op work. I’d have to build TVM with debug as I only have the release version right now.

Hi, do you solve this propblem? I met the same issue.
