Support DS2 model about paddle2onnx

[kuke]

@VictorBebnev We don't have a plan yet, because DeepSpeech is in V2 API and the convertor here only supports Fluid API.

[VictorBebnev]

This isn't converter V2 API to Fluid API?

[kuke]

No. It only Merge the model config and parameters into one file for V2 APIs.

[VictorBebnev]

Hm, converter V2 API to Fluid API doesn't exist?
In Fluid plan you have line( 5.1 convert v2 model to fluid model) about it.

[kuke]

As far as I know, the conversion from V2 to Fluid is not ready yet, and it has nothing to do with the convertor here.

[VictorBebnev]

Tell me please where i can check status of this converter. It is very important for my project.

[kuke]

Cannot give a detailed schedule yet. But if you really need Fluid APIs, you'd better develop your project based on it from now on. Waiting for the conversion from V2 to Fluid will be full of risks.

[VictorBebnev]

To implement the project, I use the pre-trained model for V2, without it I can not implement the project, there is no data on which it was trained.

[kuke]

@VictorBebnev Then I suggest you keep using V2 API, and it should be not necessary to convert the V2 model to Fluid.

[VictorBebnev]

Ok, thanks.
