# HCCL_RDMA_SL配置错误 (EI0001)

#### 问题现象

在打印日志中存在关键字"EI0001"或"Value *** for environment variable *** is invalid"，如下所示：


```
[PID:3729526]2025-10-23-17:30:40.098.984Config_Error_Invalid_Environment_Variable(
EI0001
):
Value
1000
for environment variable
HCCL_RDMA_SL
is invalid
. 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：
```

#### 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。
