I didn't have the time yet. But here is what I found: I have a process that runs a first function in which I init a ClearML Task. Then, later in my process I run a sub process that triggers a ClearML Pipeline (execute_pipeline in my example is triggered). And then the problem happens.
If I don't run the first function that inits a ClearML Task, I don't have the issue. I think it is related to the cache of clearml ?
