Hi TenseOstrich47 ,

Try using aws credentials with region too https://github.com/allegroai/clearml/blob/master/docs/clearml.conf#L88

credentials: [ specifies key/secret credentials to use when handling s3 urls (read or write) { bucket: "my-bucket-name" key: "my-access-key" secret: "my-secret-key" region: "my-region" },

each run in a different bucket

whats the specific scenario? are you running and using both buckets in the same run? each run different bucket?

TenseOstrich47 the artifacts are uploaded to the bucket according to the output_uri you provide, ClearML will not automatically upload to any bucket just because the configuration contains credentials for it

So how do I ensure that artefacts are uploaded in the correct bucket from within clearml?

great, thanks! will give that a go
