Hi AgitatedDove14 , I investigated further and got rid of a separate bug. I was able to get ignite’s events fired, but still no scalars logged 😞
There is definitely something wrong going on with the reporting of scalars using multi processes, because if my ignite callback is the following:

def log_loss(engine): idist.barrier(). # Sync all processes device = idist.device() print("IDIST", device) from clearml import Task Task.current_task().get_logger().report_text(f"{device}, FIRED, {engine.state.iteration}, {engine.state.metrics}") Task.current_task().get_logger().report_scalar("train", "loss", engine.state.metrics["loss"], engine.state.iteration) Task.current_task().get_logger().report_text(f"{device}, DONE REPORTING")Then all the reported texts are logged but not the scalars 🤔
