### Engine configuration
Includes CPU computing configurations for PaddlePaddle, Pytorch, MxNet, and Tensorflow (automatic configuration and manual configuration).
During the first run, automatic configuration will download the native engine from Amazon servers, which may be slow. Manual configuration, on the other hand, will download from a maven server (which can point to a domestic server), which is much faster. Additionally, local libraries will be bundled together, so they will not be loaded during runtime after deployment.
