Introduction
The npu-smi tool is a system management tool of NPU. It can be used to collect Atlas 300I inference card or Ascend 310 information, view the usage of the video RAM, enable or disable the NPU configuration option, and update firmware. If the NPU 20.X.X series software package is used for installation, VMs support some npu-smi commands.
