[Apache TVM Discuss] [Questions] Importing From Onnx and building through relay
Hi
I am trying to deploy a few onnx models using TVM. For that I need to import the onnx model and build it using relay and export the it as a library. I have successfully been able to do so for the models from the image classification model set from the Onnx Model Zoo.
I get errors to most of the onnx models except the image_classification models from ONNX Model Zoo.
Some of the error messages:
when I try building BiDaf
mod, params = relay.frontend.from_onnx(onnx_model, shape_dict)

This is my shape dict and related variables for BiDaf
context_string = 'A quick brown fox jumps over the lazy dog.'
query_string = 'What color is the fox?'
shape_dict = {'context_word': [len(context_string), 1],
'context_char': [len(context_string), 1, 1, 16],
'query_word': [len(query_string),1],
'query_char': [len(query_string),1, 1, 16]}
Here is the output of graph.input:

}
As you can see the element type is 8 that is enum as 8 in this dictionary that assigns the Dtype in onnx.py:
TENSOR_TYPE_TO_NP_TYPE = {
13 int(TensorProto.FLOAT): np.dtype('float32'),
14 int(TensorProto.UINT8): np.dtype('uint8'),
15 int(TensorProto.INT8): np.dtype('int8'),
16 int(TensorProto.UINT16): np.dtype('uint16'),
17 int(TensorProto.INT16): np.dtype('int16'),
18 int(TensorProto.INT32): np.dtype('int32'),
19 int(TensorProto.INT64): np.dtype('int64'),
20 int(TensorProto.BOOL): np.dtype('bool'),
21 int(TensorProto.FLOAT16): np.dtype('float16'),
22 int(TensorProto.DOUBLE): np.dtype('float64'),
23 int(TensorProto.COMPLEX64): np.dtype('complex64'),
24 int(TensorProto.COMPLEX128): np.dtype('complex128'),
25 int(TensorProto.UINT32): np.dtype('uint32'),
26 int(TensorProto.UINT64): np.dtype('uint64'),
27 int(TensorProto.STRING): np.dtype(np.object)
28 }
The dtype seems to string (8) (form here: [Enum mappings](https://deeplearning4j.org/api/latest/onnx/Onnx.TensorProto.DataType.html)) and will therefore have to of the type np.object. So there is no meaning for why I get the ' unknown type object' error here.
For MaskRCNN:
Incompatible broadcast type TensorType([1, 256, 31, 31], float32) and TensorType([1, 256, 32, 32], float32)
The type inference pass was unable to infer a type for this expression.
This usually occurs when an operator call is under constrained in some way, check other reported errors for hints of what may of happened.

This is just for 3 of the error-prone onnx models from ONNX Model Zoo.
Any help will be appreciated!
Thanks
