CANN常见错误分析

查看源文件  

本文主要介绍用户常见的CANN错误处理方法。在遇到CANN错误时，MindSpore的日志可能不足以分析相关错误，可以通过设置以下两个环境变量来打印CANN的日志以更好地分析错误：

export ASCEND_GLOBAL_LOG_LEVEL=1        # CANN日志级别，0为debug，1为info，2为warning，3为error
export ASCEND_SLOG_PRINT_TO_STDOUT=1    # 配置开启日志打屏

另外，如果需要知道图编译过程中的网络结构和算子信息，可以查看中间文件，保存IR图等中间文件进行查看。

AICORE算子编译问题

AICORE算子编译错误根据不同模块会以E5~EB开头，其中E5~E8错误码AICORE算子编译过程中一些校验报错，用户可以根据报错信息先尝试自行检查修正，而E9~EB错误码是TBE编译前后端报的错，一般来说报错就意味着算子规格TBE还不支持，可以从报错日志中获取具体信息。下面可以看一些具体的AICORE算子编译失败问题：

E80000: StridedSliceGradD输入值非法

The function call stack:
In file /home/miniconda3/envs/ci/lib/python3.7/site-packages/mindspore/ops/_grad/grad_array_ops.py(700)/        dx = input_grad(dout, x_shape, begin, end, strides)/

从上述错误码的报错信息中可以看到，StridedSliceGradD算子的参数strides中的第一个数据预期应该是1，但是实际得到的是2，故而报错。用户可以根据IR图来确认出错的算子信息，并修正strides参数。

E80012: ReduceSum算子输入维度过高

RuntimeError: ({'errCode': 'E80012', 'op_name': 'reduce_sum_d', 'param_name': 'x', 'min_value': 0, 'max_value': 8, 'real_value': 10}, 'In op, the num of dimensions of input/output[x] should be in the range of [0, 8], but actually is [10].')

从上述错误码的报错信息中可以看到，ReduceSum算子的输入和输出最高只支持8维的数据，但是实际遇到了10维的数据，故而报错。用户可以通过修改网络脚本来避免对ReduceSum输入10维的数据，从而规避这个错误。

E80029: Assign算子shape不一致问题

RuntimeError: ({'errCode': 'E80029', 'op_name': 'assign', 'param_name1': 'ref', 'param_name2': 'value', 'error_detail': 'Shape of ref and value should be same'}, 'In op[assign], the shape of inputs[ref][value] are invalid, [Shape of ref and value should be same].')

Assign算子的逻辑是使用第二个输入（即value）对第一个输入的parameter（即ref）进行赋值操作，从上述错误码的报错信息中可以看到，这两个输入预期shape应该一致，但是实际并不一致，故而报错。用户可以根据IR图来确认出错的算子，并修正Assign算子的输入。

从上述错误码的报错信息中可以看到，这个transpose算子的规格不支持，其做内存拷贝指令时数据超过了限制。针对此类问题，用户可以到MindSpore社区提交issue获取帮助。

AICORE算子执行失败，可能是数据输入不匹配、访问越界、计算溢出等问题，也有可能是算子本身代码问题。针对此类问题用户可以通过日志和dump数据先自行排查，构造单算子用例进行定位，若无法定位出问题可以到MindSpore社区提交issue获取帮助。

AICPU算子执行失败，可能是数据输入不匹配、访问越界、AICPU线程挂死等问题，也有可能是算子本身代码问题。针对此类问题用户可以通过日志和dump数据先自行排查，构造单算子用例进行定位，若无法定位出问题可以到MindSpore社区提交issue获取帮助。

runtime常见问题

Runtime模块对上承接MindSpore、ACL、GE、HCCL的调用，对下通过Driver模块对NPU上的各个模块进行调度，Runtime模块的错误码以EE开头。

遇到此类报错，可以先排查跑程序的卡是否已经被其他程序占用。目前MindSpore在Ascend环境上同一Device（即同一张卡）只支持同时跑一个程序，在910训练服务器上执行程序时会一次性申请32212254720KB（即30GB）的显存，故若报错信息中显示申请失败的显存大小为32212254720，则很有可能是该Device已经被其他程序占用，导致新程序申请显存失败。遇到这个问题只需确认卡未被其他程序占用后重新启动程序即可。若报错信息中显示申请失败的显存大小不为32212254720，而是其他任意数字，则可能是网络模型太大，超过了Device的显存（910服务器为32GB），可以考虑改小batchsize、对网络模型进行优化或者使用模型并行等手段来作训练。

另外，当前MindSpore在程序初始化时会对Device的剩余片上显存做校验，若剩余片上显存小于总量的一半，就会报以下错误提示卡被占用：

一般此类错误有可能是GetNext取数据超时或者控制流、流分配等框架问题。用户可以先自行排查一下是否是GetNext取数据超时导致的问题，以下一些原因可能会导致GetNext取数据超时：

  1. 用户脚本中消费数据量大于生产数据量。

  2. 在执行多卡分布式程序时，其中某张卡的进程挂了可能会导致其他卡取数据超时。

如果排查后不是GetNext取数据超时的问题，用户可以到MindSpore社区提交issue获取帮助。

HCCL&HCCP常见问题

HCCL(Huawei Collective Communication Library)是华为集合通信库，提供了深度学习训练场景中服务器间高性能集合通信功能，其通信过程分为如下三个阶段：

  1. 通信初始化：获取必要的集合通信参数配置并初始化网络设备。初始化阶段不涉及不同设备之前的交互。

  2. 建立通信连接：建立socket连接并交换通信两端的通信参数和内存信息。建立通信连接阶段，HCCL会根据用户提供的集群信息结合网络拓扑与其他卡进行建链并交换用于通信的参数信息。如果在建链超时时间阈值（MindSpore默认设置600s，可通过环境变量HCCL_CONNECT_TIMEOUT配置）内未得到其他卡的及时响应，会上报建链超时错误并退出训练。

  3. 执行通信操作：通过Notify同步设备执行状态，传递内存数据。通信操作执行阶段，HCCL会根据通信算法编排NOTIFY/SDMA等task并通过runtime下发给昇腾设备task调度器，设备根据编排信息调度并执行task。其中Notify类task用于卡间同步，Notify wait会阻塞task流执行直到对应的Notify record到达，以确保后续的通信操作执行时彼此的内存处于ready状态。

HCCL&HCCP的错误码以EI和EJ开头，在整个通信过程中，集群中出现的单卡问题、通信链路问题均可能会导致集群出现大量的超时错误，因此在定位集群通信问题时需要收集整个集群的日志信息，锁定问题出现的位置。

EI0006: socket建链超时

当socker建链超时时，会报EI0006错误码，同时MindSpore日志会出现Distribute Task Failed的报错，说明集群出现socket建链超时错误，如下述日志所示：

- Ascend Error Message:
----------------------------------------------------
EI0006: Getting socket times out. Reason: 1. The remote does not initiate a connect request. some NPUs in the cluster are abnormal.    2. The remote does not initiate a connect request because the collective communication operator is started too late or is not started by some NPU in the cluster.    3. The communication link is disconnected. (For example, the IP addresses are not on the same network segment or the TLS configurations are inconsistent.)
        Solution: 1. Check the rank service processes with other errors or no errors in the cluster.2. If this error is reported for all NPUs, check whether the time difference between the earliest and latest errors is greater than the connect timeout interval (120s by default). If so, adjust the timeout interval by using the HCCL_CONNECT_TIMEOUT environment variable.3. Check the connectivity of the communication link between nodes. (For details, see the TLS command and HCCN connectivity check examples.)

- Framework Error Message: (For framework developers)
----------------------------------------------------
Distribute Task Failed,
error msg: davinci_model : load task fail, return ret: 1343225860

如日志中所说，socket建链超时常见的的原因有：

  1. 部分卡未执行到正确的建链阶段，在之前已出错；

  2. 部分卡被某些耗时较长的任务阻塞，在超过600秒（可通过HCCL_CONNECT_TIMEOUT配置）后才执行到对应阶段；

  3. 节点间通信链路不通或者不稳定。

在收集了集群所有卡的INFO日志（包括CANN日志）后，可以按照以下步骤进行排查：

  1. 检查所有卡的报错日志，若有卡未报socket建链超时错误，可以通过日志时间检查判断此卡是否存在业务进程报错退出、卡死或core宕机的情况导致集群socket建链超时，然后转单卡问题定位；

  2. 若所有卡均上报socket建链超时错误，则检查各卡的错误日志中最早和最晚的时间差异是否超过超时阈值，若超过阈值请定位报错时间最晚的rank执行阻塞原因或者调整超时阈值（MindSpore默认设置为600秒，通过环境变量HCCL_CONNECT_TIMEOUT设置）；

  3. 检查集群中是否存在Device网口通信链路不通的情况，比较常见的原因：

    a. IP不在同一网段或子网掩码配置存在问题；

    b. IP冲突，集群中存在IP相同的两个rank；

    c. 各rank的TLS(安全增强)设置不一致。

EI0002: notify wait超时

常见于执行阶段，HCCL算子的task会在指定集群的每个Device上执行，并通过notify进行状态同步，若任何一张卡或者通信链路在执行前/中发生异常，则会导致集群同步失败，剩余卡会出现notify wait超时，报EI0002错误，如下所示：

The number of training samples of each NPU is inconsistent.4. Packet loss or other connectivity problems occur on the communication link.
        Solution: 1. If this error is reported on part of these ranks, check other ranks to see whether other errors have been reported earlier.2. If this error is reported for all ranks, check whether the error reporting time is consistent (the maximum difference must not exceed 1800s). If not, locate the cause or adjust the locate the cause or set the HCCL_EXEC_TIMEOUT environment variable to a larger value.3. Check whether the completion queue element (CQE) of the error exists in the plog(grep -rn 'error cqe'). If so, check the network connection status.

如日志中所说，notify wait超时常见的的原因有：

  1. 部分卡未能成功执行到notify同步阶段，在之前已出错；

  2. 部分卡被某些耗时较长的任务阻塞，在超过1800秒（可通过HCCL_EXEC_TIMEOUT配置）后才执行到对应阶段；

  3. 网络模型等原因导致某些卡间的task执行序列不一致；

  4. 节点间通信链路不稳定。

  3. 检查集群中是否存在Device网口通信链路不稳定的情况，排查所有卡的Device侧日志，若存在error cqe的打印且时间位于业务区间内，则请定位网络丢包的原因。

遇到此类报错，根据日志的初始化错误原因及解决方案进行解决即可。

profiling常见问题

profiling问题错误码以EK开头。

EK0001: 非法参数问题

当CANN的profiling模块接口遇到非法参数时会报EK0001错误。对用户来说，最常见的非法参数错误就是profiling的路径设置不对，比如下述报错：

[ERROR] PROFILER(138694,ffffaa6c8480,python):2022-01-10-14:19:56.741.053 [mindspore/ccsrc/profiler/device/ascend/ascend_profiling.cc:51] ReportErrorMessage] Ascend error occurred, error message:

RuntimeError: mindspore/ccsrc/profiler/device/ascend/ascend_profiling.cc:79 InitProfiling] Failed to call aclprofInit function.

从ERROR日志的CANN报错信息中可以获知，profiling的路径字符只能包含A-Za-z0-9-_，而上述报错中的profiling路径中含有中文两字，导致路径非法报错，从而导致profiling初始化失败。遇到此类问题，根据报错信息改正profiling路径或者其他参数即可。
