APIs

Describe

Due to historical reasons, there are many kinds of API in paddle inference at present, which is a great challenge for users to use. Therefore, we re optimized the API. The details are as follows:

1. We support forward compatibility, that is, all previous APIs can be used, but will be officially removed in the next two versions.

2. In this version，all interfaces in paddle_infer namespace.

3. Use paddle_infer::Config to do inference configuration.

4. Use paddle_infer:: Tensor to represent input and output

5. Use paddle_infer::Predictor to represent the inference engine.

6. Use paddle_infer::CreatePredictor(Config&config) to create inference engine.
