Ok. Found the solution.
The importance is to use this:

Task.add_requirements("requirements.txt")
task = Task.init(project_name='hieutest', task_name='foo',reuse_last_task_id=False)

And not:

task = Task.init(project_name='hieutest', task_name='foo',reuse_last_task_id=False)
task.add_requirements("requirements.txt")

but then it still missing a bunch of library in the Taks (that succeed) > Execution > INSTALLED PACKAGES
So when I do a clone of that task, and try to run the clone, the task fail because it is missing python package 😞

Hi @<1576381444509405184:profile|ManiacalLizard2> , I think the correct format is PACKAGE @ git+ None

that format is correct as I can run pip install -r requirements.txt
using the exact same file

@<1576381444509405184:profile|ManiacalLizard2> can you try putting it in the repository's requirements.txt instead of adding it in code?

it is actually in the repo root folder.

is task.add_requirements("requirements.txt") redundant ?
Is ClearML always look for a requirements.txt in the repo root ?

and in the train.py , I have task.add_requirements("requirements.txt")

(I use ssh key to access to our git server in our private network)

interesting, the issue happen with mamba venv. Now I use a python native venv and it is detecting correctly
