HTCondor卷影异常：[Errno 8]执行格式错误

Question

我是HTcondor的新手，在我通过Putty提交作业后，该作业被搁置，日志文件显示以下错误：

007 (274036.000.000) 06/28 23:12:08 Shadow exception!
    Error from slot1@hana-******: Failed to execute '/var/lib/condor/execute/dir_107122/condor_exec.exe': (errno=8: 'Exec format error')
     0  -  Run Bytes Sent By Job
     16520  -  Run Bytes Received By Job
     ...

012 (274036.000.000) 06/28 23:12:08 Job was held.
     Error from slot1@hana-2.*******: Failed to execute'/var/lib/condor/execute/dir_107122/condor_exec.exe': (errno=8: 'Exec format error')
     Code 6 Subcode 8
     ...

下面是我的提交描述文件：

# defining the programm
cmd = /***/my_prog.ipynb
# defining the parameters

#args = /***/model_1/data_1.csv
#args = /***/model_2/data_2.csv
#args = /***/model_3/data_3.csv
#args = /***/model_4/data_4.csv
# defining memory requirements
request_memory = 100 GB
# defining to use 1 CPU
request_cpus = 100
# defining the max. run time of the job
+REQUESTED_WALLTIME = 72
# defining the mail address for notification
notify_user = ***@**.com
notification = Always
should_transfer_files = if_needed
when_to_transfer_output = on_exit
output = $(Cluster)-$(Process)_job.out
error = $(Cluster)-$(Process)_job.error
log = $(Cluster)-$(Process)_job.log
queue 1

在本例中，my_prog.ipynb本身具有读取本地四个文件作为输入的代码，同时，my_prog.ipynb还包含将结果写入本地文件的“打印”命令。

基于这种情况，我真的很困惑，我是否也应该在提交的描述文件中配置args？

请给我任何小提示，这个问题让我艰难了3天…

任何建议都将不胜感激！

谢谢!

Answer 1

在我的例子中，我得到了这个错误，因为作业是一个python脚本，并且它的第一行没有shebang。

Answer 2

检查可执行文件的执行权限。我认为影子日志显示未设置可执行位。
