Hi SkinnyPanda43

cannot schedule new futures after interpreter shutdown

This seems like a strange exception...
What's the setup here ? jupyter notebook ? how is the interpreter down ?

Weird issue, I'll make sure we fix compatibility with python 3.9

So downgrading to python 3.8 would be a workaround?

Yes, tried with python 3.8, now it works.

I get the same error:

⋊> /d/c/p/c/e/reporting on master ◦ python model_config.py (longoeixo) 17:48:14

This is being started as a command line script.

Also tried saving the model with:
task.set_model_config(cfg.model) task.update_output_model("best_model.onnx")But got the same exception,

Its a S3 bucket, it is working since I am able to upload models before this call and also custom artifacts on the same script.
Ubuntu 18.04
Python: 3.9.5
Clearml: 1.0.4

What's the output_uri you are passing ?
And the OS / Python version?

SkinnyPanda43 issue verified, this seems to be related to python 3.9 and subprocesses.
Let me check what we can do

Is this example working for you?
