Ascendc msOpST测试报错问题

本文主要是验证基于自定义算子工程的算子开发的流程，发现了一些坑，在此记录一下。

背景

具体内容可以参考
基于自定义算子工程的算子开发

从算子工程编译部署下遇到一些问题，具体看“自定义算子包安装部署”。

在自定义算子包所在路径下，执行如下命令，安装自定义算子包。
./custom_opp_<target os>_<target architecture>.run
命令执行成功后，自定义算子包中的相关文件将部署至当前环境的OPP算子库的vendors/customize目录中，如果用户部署多个自定义算子包，可通过如下命令指定路径安装：
./custom_opp_<target os>_<target architecture>.run --install-path=<path>
说明：如果部署算子包时通过配置–install-path参数指定了算子包的安装目录，则在使用自定义算子前，需要执行source <path>/vendors/<vendor_name>/bin/set_env.bash命令，set_env.bash脚本中将自定义算子包的安装路径追加到环境变量ASCEND_CUSTOM_OPP_PATH中，使自定义算子在当前环境中生效。

问题

1、ASCEND_CUSTOM_OPP_PATH变量设置

在执行 ./custom_opp_<target os>_<target architecture>.run时，一定要注意ASCEND_CUSTOM_OPP_PATH变量的设置问题。先看问题，

case执行失败，问题报错如下：

b'EZ3003: [PID: 10178] 2025-07-23-16:59:10.249.679 No supported Ops kernel and engine are found for [AddCustom], optype [AddCustom].'

猜测是算子的注册不对。然后查看ASCEND_CUSTOM_OPP_PATH问题，如下：

root@hostname-bnq0f:/usr/local/Ascend/ascend-toolkit/latest/python/site-packages/bin# echo $ASCEND_CUSTOM_OPP_PATH
/usr/local/Ascend/mindie/latest/mindie-rt/ops/vendors/aie_ascendc:/usr/local/Ascend/mindie/latest/mindie-rt/ops/vendors/customize:

发现ASCEND_CUSTOM_OPP_PATH除自定义算子的路径外，还有一个是/usr/local/Ascend/mindie/latest/mindie-rt/ops/vendors/aie_ascendc路径。这里做一个猜测，自定义的算子并没有安装在/usr/local/ascend下面话，可能找不到算子。

接下来做个实验，将ASCEND_CUSTOM_OPP_PATH设置为/usr/local下的路径。

step1：

export ASCEND_CUSTOM_OPP_PATH=/usr/local/Ascend/ascend-tool-kit/latest/opp

step2：
再次安装自定义算子的run包

SUCCESS

发现算子包已经准确安装在了/usr/local下面：/usr/local/Ascend/ascend-toolkit/latest/opp/vendors/customize/。

step3：再次执行用例

从报错来看，是[ERROR] The path /usr/local/Ascend/ascend-toolkit/latest/opp is soft link. Not support，也就是说路径中有软链接，不支持。
设置为绝对真实路径。注意：从实验上看，路径上不能有任何软链接路径，否则都会失败

export ASCEND_CUSTOM_OPP_PATH=/usr/local/Ascend/ascend-toolkit/8.1.RC1/opp

再次执行，然后测试通过了

难道一定要这样才能解决么？官网的资料那岂不是没说清楚？带着这些疑问，再次展开探索。

2、ASCEND_CUSTOM_OPP_PATH变量一定的这样设置吗？

首先，注意到算子自定义run包安装的时候，有提供自定义安装的路径，如下：

如果用户部署多个自定义算子包，可通过如下命令指定路径安装：
./custom_opp_<target os>_<target architecture>.run --install-path=<path>
说明：如果部署算子包时通过配置–install-path参数指定了算子包的安装目录，则在使用自定义算子前，需要执行source <path>/vendors/<vendor_name>/bin/set_env.bash命令，set_env.bash脚本中将自定义算子包的安装路径追加到环境变量ASCEND_CUSTOM_OPP_PATH中，使自定义算子在当前环境中生效。

那么通过这种方式是否能执行成功呢？/home/add_custom_test/是自定义的路径。

root@hostname-bnq0f:/home/ascendc/samples/operator/ascendc/0_introduction/1_add_frameworklaunch/AddCustom/test# ./build_out/custom_opp_openEuler_aarch64.run --install-path=/home/add_custom_test

SUCCESS

按照资料中的提示，算子安装完成后，需要执行source /home/add_custom_test/vendors/customize/bin/set_env.bash。
执行上述的source命令后，继续进行测试，发现一个问题：

算子编译失败，主要是因为fatal error: 'cstdint' file not found"，这里请参考文章：Ascendc helloworld编译问题，需要设置CPLUS_INCLUDE_PATH环境变量，如下：

export CPLUS_INCLUDE_PATH=/usr/include/c++/12:/usr/include/c++/12/aarch64-openEuler-linux

那为什么使用默认ASCEND_CUSTOM_OPP_PATH（带mindie）不行，而指定路径行呢？
安装算子run包中，注意到描述：

需要执行source /home/add_custom_test/vendors/customize/bin/set_env.bash。

这个脚本里面又是什么内容？查看/home/add_custom_test/vendors/customize/bin/set_env.bash，内容如下

#!/bin/bash
export ASCEND_CUSTOM_OPP_PATH=/home/add_custom_test/vendors/customize:${ASCEND_CUSTOM_OPP_PATH}
export LD_LIBRARY_PATH=/home/add_custom_test/vendors/customize/op_api/lib/:${LD_LIBRARY_PATH}

也就是添加了customize路径到ASCEND_CUSTOM_OPP_PATH，添加二进制文件到LD_LIBRARY_PATH。
也就是说只需要修改这2个环境变量的内容，即可让算子执行成功。
那为什么MindIE的默认环境变量下没有执行成功？默认环境变量ASCEND_CUSTOM_OPP_PATH在安装完算子后内容如下：

/usr/local/Ascend/mindie/latest/mindie-rt/ops/vendors/aie_ascendc:/usr/local/Ascend/mindie/latest/mindie-rt/ops/vendors/customize:

ASCEND_CUSTOM_OPP_PATH没有问题。那么问题出现在LD_LIBRARY_PATH这个环境变量。观察LD_LIBRARY_PATH需要设置的内容是customize/op_api/lib/路径，查看/usr/local/Ascend/mindie/latest/mindie-rt/ops/vendors/customize下的/op_api/lib/路径，发现根本就没有这个路径：

root@hostname-bnq0f:/usr/local/Ascend/ascend-toolkit/latest/python/site-packages/bin# ll /usr/local/Ascend/mindie/latest/mindie-rt/ops/vendors/customize/
total 12
dr-xr-x--- 4 root root 4096 May 23 10:50 framework
dr-xr-x--- 5 root root 4096 May 23 10:50 op_impl
dr-xr-x--- 2 root root 4096 May 23 10:50 op_proto

问题到这里差不多知道原因了，是算子的二进制lib文件路径并没有准确的设置到LD_LIBRARY_PATH中。
那么默认路径下，为什么没有生成op_api？这里肯定是个bug（该页面提个issue去解决）。

补充：
经过与ascendc小伙伴沟通，最终的原因是ASCEND_CUSTOM_OPP_PATH路径只能有一个，使用冒号不能区分，如下这种：

/usr/local/Ascend/mindie/latest/mindie-rt/ops/vendors/aie_ascendc:/usr/local/Ascend/mindie/latest/mindie-rt/ops/vendors/customize:

而如果ASCEND_CUSTOM_OPP_PATH是单个路径：

/usr/local/Ascend/mindie/latest/mindie-rt/ops/vendors/aie_ascendc

该问题就能解决。

总结

总结一句话就是，自定义算子测试要准确的设置ASCEND_CUSTOM_OPP_PATH和LD_LIBRARY_PATH这2个环境变量，否则会执行失败。
