使用dlc命令行工具查看任务详情 - 人工智能平台 PAI

您可以通过客户端工具查看任务日志、任务列表和任务详情。本文介绍查询相关的命令详情，包括调用格式、参数解释及使用示例。

查看任务日志（logs）

功能
查看一个训练任务的日志详情。

格式

./dlc logs <yourJobId> <yourPodId> [--max_events_num <yourMaxNum>] [--start_time <yourStartTime>] [--end_time <yourEndTime>]

参数

参数	是否必选	描述	类型
<yourJobId>	是	待查看训练任务的ID。	STRING
<yourPodId>	是	待查看日志的实例（Pod）ID。在分布式任务场景下，存在多个实例（Pod）。	STRING
max_events_num <yourMaxNum>	否	返回的日志最大行数，默认值为2000。	INT
start_time <yourStartTime>	否	日志查询的起始时间，默认值为7天前。例如，start_time 2020-11-08T16:00:00Z。	STRING
end_time <yourEndTime>	否	日志查询的截止时间，默认值为当前时间。例如，end_time 2020-11-08T17:00:00Z。	STRING

示例

针对分布式训练任务的0号Worker节点，获取十行日志。

./dlc logs dlcdys3r9jlu**** dlcdys3r********-worker-0 --max_events_num 10

系统返回如下类似结果。

查看任务列表与状态

功能
获取训练任务的信息。如果不指定JobID，则会将所有的任务信息列出；如果指定了JobID,则只会展示对应的任务信息。

格式

./dlc get job [JOB_ID] [--workspace_id <yourWorkspaceId>] [--display_name <yourJobName>] [--job_type <yourJobType>] [--status <yourJobStatus>] [--start_time <yourStartTime>] [--end_time <yourEndTime>] [--page_num <yourPageNum>] [--page_size <yourPageSize>] [--max_events_num <yourMaxNum>] [--events] [--events_only]

参数

参数	是否必选	描述	类型
JOB_ID	否	待查看训练任务的ID。	STRING
workspace_id <yourWorkspaceId>	否	工作空间ID。	STRING
display_name <yourJobName>	否	任务名称，支持模糊查询，不支持通配符查询，大小写不敏感。	STRING
job_type <yourJobType>	否	任务类型，支持查询所有任务类型。默认为空，代表所有类型。	STRING
status <yourJobStatus>	否	任务状态。默认为空，代表任务所有状态。	STRING
start_time <yourStartTime>	否	查询区间的起始时间，使用任务的创建时间来过滤。例如：start_time 2022-08-04T02:09:32Z。	STRING
end_time <yourEndTime>	否	查询区间的截止时间，使用任务的创建时间来过滤。例如：end_time 2022-08-04T02:09:32Z。	STRING
page_num <yourPageNum>	否	分页查询，指定当前查询需要返回的页码，编号从1开始，默认为1。	INT
page_size <yourPageSize>	否	分页查询中，指定当前查询每页返回的数量，默认为10。	INT
max_events_num <yourMaxNum>	否	返回的系统事件的最大行数，默认为2000。	INT
events	否	是否查询任务的系统事件，仅查询单个任务时才会生效。默认为false。	BOOL
events_only	否	是否只查询任务的系统事件，仅查询单个任务时才会生效。默认为false。	BOOL

示例

按照任务名称模糊匹配查询所有的训练任务。

./dlc get job --display_name epl

系统返回如下类似结果。
