最近在搞华为 AI 加速器的适配
用的 ascend310 和 Atlas 300I 推理卡（型号：3010）
我在华为云开了一个 ascend310+ubuntu18.04 的实例
在 onnx 模型转成 om 模型的时候，遇到了一堆问题，各种算子不支持
然后，询问华为昇腾工程师之后，建议我升级 cann 的版本
https://gitee.com/ascend/modelzoo/issues/I7S5KS
我查看了新开的 ascend310+ubuntu18.04 的 cann 版本是商业版，但是是特别古老 20.1.rc1 版本
此时最新的商业版已经是 23.0.RC2
https://www.hiascend.com/zh/hardware/firmware-drivers/commerc...
我就得升级 cann 的版本
但是我不想升级商业版，因为需要特别的账号才能下载，太麻烦了，所以我就想着用社区版算了
社区版的下载地址：https://www.hiascend.com/software/cann/community
但是因为本机已经预装了 20.1.rc1，我不想覆盖，所以就得额外找个地方安装最新的社区版 7.0.RC1
那怎么指定 7.0.RC1 的安装路径呢？
可以使用 --install-path 参数指定
示例如下：
./Ascend-cann-toolkit_7.0.RC1.alpha001_linux-x86_64.run --install --install-path=/opt/Ascend-cann-toolkit_7.0.RC1
运行结果：
(samples) root@ascend310:~/code/samples# ./Ascend-cann-toolkit_7.0.RC1.alpha001_linux-x86_64.run --install --install-path=/opt/Ascend-cann-toolkit_7.0.RC1

Please make sure that the environment variables have been configured.
- To take effect for all users, you can add "source /opt/Ascend-cann-toolkit_7.0.RC1/ascend-toolkit/set_env.sh" to /etc/profile.
- To take effect for current user, you can exec command below: source /opt/Ascend-cann-toolkit_7.0.RC1/ascend-toolkit/set_env.sh or add "source /opt/Ascend-cann-toolkit_7.0.RC1/ascend-toolkit/set_env.sh" to ~/.bashrc.
***WARNING***To ensure Toolkit's normal function, please check the driver installation manually.
(samples) root@ascend310:~/code/samples# 记得要使用新的 acnn 的话，如何设置环境变量
在安装路径下 /opt/Ascend-cann-toolkit_7.0.RC1/ascend-toolkit/7.0.RC1.alpha001/x86_64-linux/script/set_env.sh 就有
注意，我的安装路径是 /opt/Ascend-cann-toolkit_7.0.RC1/ascend-toolkit/7.0.RC1.alpha001，如果你的路径是其他，那么我们的前缀是不一样的
内容如下：
export LD_LIBRARY_PATH=/usr/local/Ascend/driver/lib64:/usr/local/Ascend/driver/lib64/common:/usr/local/Ascend/driver/lib64/driver:$LD_LIBRARY_PATH
export ASCEND_TOOLKIT_HOME=/opt/Ascend-cann-toolkit_7.0.RC1/ascend-toolkit/7.0.RC1.alpha001
export LD_LIBRARY_PATH=${ASCEND_TOOLKIT_HOME}/lib64:${ASCEND_TOOLKIT_HOME}/lib64/plugin/opskernel:${ASCEND_TOOLKIT_HOME}/lib64/plugin/nnengine:$LD_LIBRARY_PATH
export PYTHONPATH=${ASCEND_TOOLKIT_HOME}/python/site-packages:${ASCEND_TOOLKIT_HOME}/opp/built-in/op_impl/ai_core/tbe:$PYTHONPATH
export PATH=${ASCEND_TOOLKIT_HOME}/bin:${ASCEND_TOOLKIT_HOME}/compiler/ccec_compiler/bin:$PATH
export ASCEND_AICPU_PATH=${ASCEND_TOOLKIT_HOME}
export ASCEND_OPP_PATH=${ASCEND_TOOLKIT_HOME}/opp
export TOOLCHAIN_HOME=${ASCEND_TOOLKIT_HOME}/toolkit
export ASCEND_HOME_PATH=${ASCEND_TOOLKIT_HOME}
然后上面的环境变量，复制粘贴回车，此时你的终端就可以使用新的 acnn 了
注意，以后每开启一个新的终端，都需要这样操作

手把手教你把 onnx 转成 om，然后调用 python+acl 调用 om 推理
上面的问题要怎么解决？
看到这篇 QA，https://gitee.com/ascend/samples/issues/I4N5SF
里面提到，但我们升级了 cann 的时候，因为升级幅度比较大，所以驱动也要一起升级
好吧，让我们一起来升级驱动吧！
驱动下载地址：https://www.hiascend.com/zh/hardware/firmware-drivers/communi...
至于下载哪个驱动版本？我不知道，我只知道我用的 cann 是最新，那么驱动也用最新肯定没错
