Question about sequence/map input onnx type from model

[qw2208]

1. Is there a way to get the non-tensor types from the onnx model?
   For example, if the model input is of type: std::vector<std::map<int64_t, float>>, I could get the input type of ONNX_TYPE_SEQUENCE by running session->GetInputTypeInfo(i).GetONNXType();
   However, I'm confused how I could continue to get the type of the map while creating Ort::Value using the CXX api?
2. Another question is when loading the Bert model from Bert_model, one of the input shapes is [-1, 256] (Actually this model converted from Tensorflow and the inputs shape all starts with -1). Is the negative index supported when calling session run function? I'm getting the error of out of data bound.

I'll take a look at the second one. It shouldn't be [-1].

[snnn]

For you question two: here the -1 means unknown. You can replace it with any non-zero positive value.

[qw2208]

Yes, I did replace the -1 with 1 to all of the four inputs while getting the element out-of-bound exception as shown in the screen shot.

We'll update the model.

For 1. I'm not sure what you mean by continuing to get the type of the map. If you have an Ort::Value you can still call GetTypeInfo() on it and then call GetONNXType() the same as before?

[qw2208]

@RyanUnderhill Thanks Ryan. However, for inputs, I will not get it in Ort::Value and the GetTypeInfo() could only get the type of the outer type.

[RyanUnderhill]

@qw2208 Ah, I see what you're looking for. Yeah, currently we have no way to query subtype information of a type. I'm marking this as an enhancement as we'd need some extra interface functions like this:

OrtStatus* GetType(const OrtTypeInfo type, int index, OrtTypeInfo** out)
OrtStatus* GetTypeCount(const OrtTypeInfo type, int index, size_t* out);

First issue is resolved - available in ORT 1.2.

@vinitra can you take a look at #2 and see if the model zoo model still needs updates?
