Could you try adding region under credentials as well?

SmugDolphin23 I added a region, run experiment again. Didn't work

Can you share a snippet?

` s3 {
# S3 credentials, used for read/write access by various SDK elements

        # default, used for any bucket not specified below
        key: "mykey"
        secret: "mysecret"
        region: " ` ` "

        credentials: [

             {
                 bucket: "mybucket"
                 key: "mykey"
                 secret: "mysecret"
                 region: " ` ` "
              }, `

it's pretty much the same

I meant the code where you upload an artifact, sorry

` from random import random
from clearml import Task, TaskTypes

args = {}
task: Task = Task.init(
project_name="My Proj",
task_name='Sample task',
task_type=TaskTypes.inference,
auto_connect_frameworks=False
)
task.connect(args)
task.execute_remotely(queue_name="default")
value = random()
task.get_logger().report_single_value(name="sample_value", value=value)
with open("some_artifact.txt", "w") as f:
f.write(f"Some random value: {value}\n")
task.upload_artifact(name="test_artifact", artifact_object="some_artifact.txt") `

SmugDolphin23

The code is run from another machine where clearml.conf configured to connect to ClearML server, no other configurations are provided

check the output_uri parameter in Task.init

You need to specify it. Or you could specify this in your config: https://github.com/allegroai/clearml/blob/54c601eea2f9981bb8e360a8203bc36696a55cfd/clearml/config/default/sdk.conf#L164

SmugDolphin23 Thank you very much!
That's clearml.conf for ClearML end users right?

it's the same file you added your s3 creds to

Oh, it's configured o agent machine, got you

A bit overwhelmed by configuration, since it has an agent, a server and bunch of configuration files, easy to mess up

Yeah, that's always the case with complex systems 😕

SmugDolphin23 Sorry to bother again, output_uri should be a URI to S3 endpoint or clear ml fileserver? If it's not provided artifacts are stored locally, right?

The S3 endpoint

And I believe that by default we send artifacts to the clearml server if not specified

The only expection is the models if I'm not mistaken, which are stored locally by default.

SmugDolphin23 Got it. Now I am a bit confused about region parameter in s3 section. Amazon docs say that region could be a regular URL with protocol like https://etc.etc which my endpoint actually is. I plugged it in s3 section in clearml.conf. Should it stay that way?

I think that will work, but I'm not sure actually. I know for sure that something like us-east-2 is supported

@<1523701435869433856:profile|SmugDolphin23> I actually don't know where to get my region for the creds to S3 I am using. From what I figured, I have to plug in my sk, ak and bucket into credentials in agent and output URI must be my S3 endpoint — complete URI with protocol. Is it correct?

@<1526734383564722176:profile|BoredBat47> Yeah. This is an example:

 s3 {
            key: "mykey"
            secret: "mysecret"
            region: "us-east-1"
            credentials: [
                 {
                     bucket: "

"
                     key: "mykey"
                     secret: "mysecret"
                    region: "us-east-1"
                  },
            ]
}
# some other config
default_output_uri: "

"

@<1523701435869433856:profile|SmugDolphin23> Hello, again! I tried to fill the values by your example. Still no luck. I noticed console log on my task says that I have certificate error. I disabled it in api section in clearml.conf like this: verify_certificate = false and I still have SSL error. Any clues why would that be?

@<1526734383564722176:profile|BoredBat47> the bucket name in your case should just be somebucket (and should not start with s3:// )

How can you have a certificate error if you're using S3? I'm sure their certificate is OK...

@<1523701087100473344:profile|SuccessfulKoala55> Could you provide a sample of how to properly fill all the necessary config values to make S3 work, please?
My endpoint starts with https:// and I don't know what my region is, endpoint URL doesn't contain it.
Right now I fill it like this:

aws.s3.key = <access-key>
aws.s3.secret = <secret-key>
aws.s3.region = <blank>
aws.s3.credentials.0.bucket = <just_bucket_name>
aws.s3.credentials.0.key = <access-key>
aws.s3.credentials.0.secret = <secret-key>
sdk.development.default_output_uri = <

@<1523701087100473344:profile|SuccessfulKoala55> Fixed it by setting env var with path to certificates. I was sure that wouldn't help since I can curl and python get request to my endpoint from shell just fine. Now it says I am missing security headers, seems it's something on my side. Will try to fix this
