-When [MindSpore Lite](https://www.mindspore.cn/lite) is used as the inference backend, MindSpore Serving supports Atlas 200/300/500 inference product, Atlas inference series, Nvidia GPU and CPU environments. Only the `MindIR_Lite` model formats is supported. Models of format `MindIR` exported from MindSpore or models of other frameworks need be be converted to `MindIR_Lite` format by the MindSpore Lite conversion tool. The `MindIR_Lite` models converted from `Ascend310` and `Ascend310P` environments are different, and the `MindIR_Lite` models must be running on the corresponding `Ascend310` or `Ascend310P` environments. `MindIR_Lite` models converted from Nvidia GPU and CPU environments can be running only in the Nvidia GPU and CPU environments.
