Expected value : range[0, 7].针对Atlas 推理系列产品、Atlas 训练系列产品、Atlas A2 训练系列产品/Atlas A2 推理系列产品、Atlas A3 训练系列产品/Atlas A3 推理系列产品CANN日志的ERROR日志中存在关键字externalinput.cc表示是在读取环境变量配置时报错如下所示[ERROR]HCCL(3729526,python3.11):2025-10-23-17:30:40.098.973 [externalinput.cc:963] [3729526][Parse][rdmaServerLevel]HCCL_RDMA_SL[1000] is invalid. except: [0, 7] [ERROR]HCCL(3729526,python3.11):2025-10-23-17:30:40.099.058 [externalinput.cc:169] [3729526][InitGroupStage][EnvConfig]errNo[0x0000000005000001] In init env variable param, parse HCCL_RDMA_SL failed. errno[1] [ERROR]HCCL(3729526,python3.11):2025-10-23-17:30:40.099.063 [externalinput.cc:47] [3729526][InitExternalInput]call trace: hcclRet - 1 [ERROR]HCCL(3729526,python3.11):2025-10-23-17:30:40.099.068 [op_base.cc:866] [3729526][HcclGetRootInfo]call trace: hcclRet - 1可能的原因及解决方法环境变量配置参数不符合要求请基于日志打印的建议调整取值范围如果仍然有疑问请参照对应环境变量参考。HCCL_SOCKET_IFNAME配置错误 (EI0001)问题现象在CANN日志中存在关键字get host ip fail by socket Ifname如下所示[ERROR] HCCL(925892,alltoall_test):2025-10-28-16:34:59.634.432 [sal.cc:501] [925892][InitGroupStage][EnvConfig]set ifname to [abc] by HCCL_SOCKET_IFNAME, but not found in the environment, ifnames in the environment is as follows [ERROR] HCCL(925892,alltoall_test):2025-10-28-16:34:59.634.437 [sal.cc:504] [925892][InitGroupStage][EnvConfig]get host ip fail by socket Ifname. name[lo] ip[127.10.0.1%lo] [ERROR] HCCL(925892,alltoall_test):2025-10-28-16:34:59.634.441 [sal.cc:504] [925892][InitGroupStage][EnvConfig]get host ip fail by socket Ifname. name[enp] ip[127.10.0.2%enp] [ERROR] HCCL(925892,alltoall_test):2025-10-28-16:34:59.634.447 [sal.cc:504] [925892][InitGroupStage][EnvConfig]get host ip fail by socket Ifname. name[docker0] ip[172.17.0.1%docker0]问题根因通过HCCL_SOCKET_IFNAME环境变量指定了Host网卡但在当前的环境上没有找到对应的网卡若为容器场景需指定容器内可用的Host网卡报错日志打印列举了当前环境上查询到的Host网卡。解决方法修改HCCL_SOCKET_IFNAME环境变量指定为环境上存在的Host网卡。【免费下载链接】hccl集合通信库Huawei Collective Communication Library简称HCCL是基于昇腾AI处理器的高性能集合通信库为计算集群提供高性能、高可靠的通信方案项目地址: https://gitcode.com/cann/hccl创作声明：本文部分内容由AI辅助生成（AIGC），仅供参考
