I Have Been Successfully Deploying And Training A Pytorch Cnn On A

I have been successfully deploying and training a PyTorch CNN on a clearml-agent managed compute resource and have been testing some the capabilities, including scaling. So I have fired up another compute note, and started a clearml-agent running in the same queue to double the amount of GPU resource. I have a number of jobs sitting in the queue waiting to be trained, which are basically different network architectures on the same problem.

When the first job runs on the new compute node, it has to cache a copy of the images dataset for the problem from the clearml-server, ready for execution of the training job. This all happens as expected and the job has started training. However I keep getting the following reported to the terminal logging output:

2021-05-21 09:51:36,268 - clearml.Metrics - ERROR - Action failed <400/131: events.add_batch/v1.0 (Events not added: Invalid task id=1)>

It doesn't appear to be impacting the job or its reporting, as the metrics of the training appear to be being collected as normal on the original compute node I have been testing on.

Q. I was wondering if there was a setting required or a call relating to the dataset downloading that needed to stop the job from logging until the model is actually executed for training?

Q. Is this is a timeout issue, as it has to wait for the dataset and pre-trained model weights to download?

Hi VivaciousPenguin66 , this error indicated the SDK attempted to report metrics for a non-existent task ID (1), bit I'm not sure why...

I've not seen this before.

SuccessfulKoala55 A second queued job which executed on the same node, but didn't this time need to cache the dataset locally as it was done by the previous experiment, hasn't had this issue.

That all being said, apart from the console reporting looking messy, it doesn't appear to have impacted the training, or indeed the metric collection of the first experiment where it occurred.

This job did download pre-trained weights, so the only difference between them is the local dataset cache.

SuccessfulKoala55 However, this was the first time an experiment with this dataset was executed on this compute node. I have been doing a lot of trial and error with this setup to get the models training, and so on my first compute node, I had the data downloading locally quite early on, so I haven't seen the script have to download a local dataset cache as it was already done.
