Hello I Was Trying To Download The Task Log Using Api In Python I'M Using

Hello
I was trying to download the task log using API in Python
I'm using client.events.download_task_log(task="task_id_string") but for some reason I always get an error:
ValueError: Missing meta section in response payload
Am I missing something obvious?

PS. I'm using http://app.clear.ml with self-hosted compute cluster

If the AWS machine has an ssh key installed, it should work - I assume it's possible to either use a custom AMI for that, or you can use the autoscaler instance startup bash script

Perhaps it is connected with the issue mentioned here (since I authenticate with the same credentials)

🙂
here is a bit of code that seems to do the job. have a look
`
wrapper = Task.get_task(project_name="***", task_name="***")

req_obj = events.DownloadTaskLogRequest(wrapper.id)
res = wrapper.session.send_request(
service=req_obj._service,
action=req_obj._action,
version=req_obj._version,
json=req_obj.to_dict(),
method=req_obj._method,
async_enable=False,
headers=None,
)
print(res.json()) `

For some reason it does not work for me

req_obj = client.events.DownloadTaskLogRequest(clearml_task.id) AttributeError: 'Events' object has no attribute 'DownloadTaskLogRequest'SweetBadger76 I think you missed the events import - this is not client.events

JSON

The first thing you tried didn't work since the APIclient is not designed to receive plain text response, just Jason response

You mean downloading logs from an experiment in a workspace you've been invited to?

Any update regarding pushing new version with a fix?

SuccessfulKoala55 it's working!
Thank you very much for letting me know 😄

Yep sorry I have not pasted the import line. You should add something like this :

from clearml.backend_api.services import events

🙏

This is actually one of the only endpoints that returns this kind of output

Ah, I was actually going to ask whether this is for sure related to my issue but I figured - nah, it must me be who is not getting it 😄

I suggest using cURL and figuring out how to store the plain text response into a file

Thank you for the info!

After fixing imports I was able to successfully run the code
Thanks a lot!

However I'm still curious why the first option I pasted in the original message did not work + do you have any update about the issue when downloading logs from the UI?

Hi CrabbyKoala94
I am working on your issue, I will update you asap. Thanks

Hi CrabbyKoala94 , the download log request actually returns a different payload and is meant for the browser to intercept

Hi SuccessfulKoala55 !
Any update regarding pushing new version with a fix? 🙂

I'm not sure I got it, sorry

I'm actually running the script from my local PC with clearml-init initialized using credentials generated on ClearML settings webpage (where you generate app credentials)

I see
Thanks for explanation!

And are there any updates about downloading logs from UI bug? 🙂
