In another task I have tried to evaluate this metric but received similar error :
clearml.automation.optimization - WARNING - Could not find requested metric ('evaluate', 'val_loss') report on base task

Unfortunately, I am not running on a community server

What is the base task you are using? It looks like you're using one of the examples 🙂

I have some info that I wouldn't like to post here (due to security reasons), is there a way to share the link only with your user ? 🙂

Where is the error?

where should I look to see this metric? at the scalars tab?

Any chance you could provide a share-able link if you're running on the community server?

I indeed have different scalar there :
val_loss but I have reported this metric in the checkpoint not in the logger..

Results -> Scalars 🙂

When looking at the base task, do you have that metric there?

this is the correct file

And afterwards, I have the following output that continues for 300 iterations without further reports of metrics

Please do. You can download the entire log from the UI 🙂

But I can add screenshots of the log file if necessary

Because of a server error I can't download the log so I attached a screenshot. In the log I see only the following reports (without a summary table/plot).

It looks like you are running on the community server. Can you right click the experiment in the experiments table and click on 'Share' on all the relevant experiments and send here?

Yes, you can message me directly 🙂
