Found a trick to have empty Installed package:
clearml.Task.force_requirements_env_freeze(force=True,requirements_file="/dev/null")
Not sure if this is the right way or not ...

@<1523701070390366208:profile|CostlyOstrich36> Is there a way to tell clearml to not try to detect the Installed package ?

So I now just need to find a way to not populate Installed Package in the first place

oh, looks like I need to empty the Installed Package before enqueue the cloned task

So I tried:

CLEARML_AGENT_SKIP_PIP_VENV_INSTALL=/data/hieu/opt/python-venv/fastai/bin/python3.10
clearml-agent  daemon  --queue no_venv

Then enqueue a cloned task to no_venv
It is still trying to create a venv (and fail):

Yes

Oh, so you mean CLEARML_AGENT_SKIP_PIP_VENV_INSTALL=/path/to/my/venv/bin/python3 ??

From the environment variable

But then how did the agent know where is the venv that it needs to use?

Yes

Set that env var in the terminal before running the agent ?

you should set it on the machine running the agent

no, it's an environment variable

Should I put that in the clearml.conf file?

Hi @<1576381444509405184:profile|ManiacalLizard2> , I think this is the env var you're looking for
CLEARML_AGENT_SKIP_PIP_VENV_INSTALL
None
