How to help condor find the file it should execute in a job?

问题

I am trying to run a job, but condor can't seem to find my file.

I've made sure that:

the file is there by doing an ls and cat on its absolute path
run it from a condor interactive session
give it the right permissions so that it runs it.

I've done that but I get this error:

(automl-meta-learning) miranda9~/automl-meta-learning/automl-proj/experiments/meta_learning $ cat condor_job_log_69.out

but the file is clearly there:

(automl-meta-learning) miranda9~/automl-meta-learning/automl-proj/experiments/meta_learning $ ls -lah /home/miranda9/automl-meta-learning/automl-proj/experiments/meta_learning/meta_learning_experiments_submission.py
-rwxrwxr-x. 1 miranda9 miranda9 22K Oct 20 14:54 /home/miranda9/automl-meta-learning/automl-proj/experiments/meta_learning/meta_learning_experiments_submission.py

I don't understand why condor can't find it. Any ideas? I'm not the sys admin so I don't even know how to start debugging this.

btw my submission script:

回答1:

It looks like your executable is a python script. Linux will report "no such file or directory" when the script itself exists, but the interpreter listed on the "#!" doesn't exist on the system. Could this be what is happening here? What is the first line of this script look like?

The issue was that at the top of my python submission script I had arguments for other clusters not related to condor so the wrong path to the python executable was there. I fixed it by removing that and adding this line to my python submission script:

#!/home/miranda9/miniconda3/envs/automl-meta-learning/bin/python

in fact to find the python path for your current env do:

which python
