Ascend组件
在获取到Ascend套件的时候，必要注意安装版本的配套性，不要出现多版本混用，尽量使用商业版，而不使用社区版

开发用的动态库引用
部分情况下，使用命令source set_env.sh不一定获得很好的效果，这时候可以手动将devlib路径放到libc.conf中
ARM架构：
echo "/usr/local/Ascend/ascend-toolkit/latest/aarch64-linux/devlib" >> /ect/ld.so.conf.d/libc.conf
X86-64架构
echo "/usr/local/Ascend/ascend-toolkit/latest/x86_64-linux/devlib" >> /ect/ld.so.conf.d/libc.conf
当根据处理器架构完成配置后，使用命令重载库引用
ldconfig
实例、可供参考的通用环境配置
cat >~/.bashrc << EOF
export LD_LIBRARY_PATH=/usr/local/python3.7.5/lib/:$LD_LIBRARY_PATH
export PATH=/usr/local/python3.7.5/bin/:$PATH
export LD_LIBRARY_PATH=/usr/local/Ascend/ascend-toolkit/latest/lib64:/usr/local/Ascend/ascend-toolkit/latest/lib64/plugin/opskernel:/usr/local/Ascend/ascend-toolkit/latest/lib64/plugin/nnengine:$LD_LIBRARY_PATH

使用后，重载bashrc生效
source ~/.bashrc
完成配置，环境检测
在完成全部过程的配置后，使用命令atc，检查atc转换工具是否正常
返回值
ATC start working now, please wait for a moment.
ATC run failed, Please check the detail log, Try 'atc --help' for more information
E10004: Value for [--model] is empty.
[--framework] is required. Must be [0(Caffe) or 1(MindSpore) or 3(TensorFlow) or 5(Onnx)].
在完成全部过程的配置后，使用命令
npu-smi info
检查设备状态是否正常，如下
