I think clearml-agent tries to execute /usr/bon/python3.6 to start the task, instead of using the python used to start clearml-agent

JitteryCoyote63 can you try to look at the logs in /tmp/.clearml_agent_out.j7wo7ltp.txt ?

User aborted: stopping task usually means Task status changed or "stopping" was placed in the status_message field while the task was running

The file  /tmp/.clearml_agent_out.j7wo7ltp.txt   does not exist

SuccessfulKoala55 I tried to setup in a different machine the clearml-agent and now I get a different error message in the logs:
Warning: could not locate requested Python version 3.6, reverting to version 3.6 clearml_agent: ERROR: Python executable with version '3.6' defined in configuration file, key 'agent.default_python', not found in path, tried: ('python3.6', 'python3', 'python')

OK, that makes more sense, I guess

Python executable with version '3.6' defined in configuration file

What is configured?

in clearml.conf:
agent.package_manager.system_site_packages = true agent.package_manager.pip_version = "==20.2.3"

and in the logs:
agent.worker_name = worker1 agent.force_git_ssh_protocol = false agent.python_binary = agent.package_manager.type = pip agent.package_manager.pip_version = \=\=20.2.3 agent.package_manager.system_site_packages = true agent.package_manager.force_upgrade = false agent.package_manager.conda_channels.0 = pytorch agent.package_manager.conda_channels.1 = conda-forge agent.package_manager.conda_channels.2 = defaults agent.package_manager.torch_nightly = false agent.venvs_dir = /home/machine/.clearml/venvs-builds.1.2 agent.venvs_cache.max_entries = 10 agent.venvs_cache.free_space_threshold_gb = 2.0 agent.vcs_cache.enabled = true agent.vcs_cache.path = /home/machine/.clearml/vcs-cache agent.venv_update.enabled = false agent.pip_download_cache.enabled = true agent.pip_download_cache.path = /home/machine/.clearml/pip-download-cache agent.translate_ssh = true agent.reload_config = false agent.docker_pip_cache = /home/machine/.clearml/pip-cache agent.docker_apt_cache = /home/machine/.clearml/apt-cache.1.2 agent.docker_force_pull = false agent.default_docker.image = nvidia/cuda:10.1-cudnn7-runtime-ubuntu18.04 agent.enable_task_env = false agent.default_python = 3.6 agent.cuda_version = 0 agent.cudnn_version = 0

I execute the clearml-agent this way:
/home/machine/miniconda3/envs/py36/bin/python3 /home/machine/miniconda3/envs/py36/bin/clearml-agent daemon --services-mode --cpu-only --queue services --create-queue --log-level DEBUG --detached

agent.default_python = 3.6

if not set, this value is taken from the system python

but it is set here, right?

so the clearml-agent daemon takes 3.6 as the default, and when running the service, for some reason 3.6 is not in the path

Can I simply set agent.python_binary = path/to/conda/python3.6 ?

exactly

whatever will allow the agent daemon to create a venv 🙂

Nice, seems to work! 🎉

interestingly, it works on one machine, but not on another one

What's the error on the other machine?

Also, what do you mean by another machine? Are you running the ClearML services agent daemon on another machine?

same as the first one described

yes exactly

SInce it fails on the first machine (clearml-server), I try to run it on another, on-prem machine (also used as an agent)

Oof now I cannot start the second controller in the services queue on the same second machine, it fails with
Processing /tmp/build/80754af9/cffi_1605538068321/work ERROR: Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: '/tmp/build/80754af9/cffi_1605538068321/work' clearml_agent: ERROR: Could not install task requirements! Command '['/home/machine/.clearml/venvs-builds.1.3/3.6/bin/python', '-m', 'pip', '--disable-pip-version-check', 'install', '-r', '/tmp/cached-reqsi4hq9s6z.txt']' returned non-zero exit status 1.

I get the same error when trying to run the task using clearml-agent services-mode with docker, so weird

Ok, now I get ERROR: No matching distribution found for conda==4.9.2 (from -r /tmp/cached-reqscaw2zzji.txt (line 13))

Ok, deleting installed packages list worked for the first task

Alright SuccessfulKoala55 I was able to make it work by downgrading clearml-agent to 0.17.2
