Is there still an issue? Could it be the browser cannot access the file server directly?

Hmm there’s something wrong with the setup. I tried with the demo version of ClearML then it works:

Hi @<1560798754280312832:profile|AntsyPenguin90>
The image itself is uploaded in a blackground process, flush just triggers the starting of the process.
Could it be that it is showing a few seconds after?

May you elaborate little bit more on this? Right now I'm using the default file server provided by ClearML, ie ipaddress:8081

Are any files uploaded? Like artifacts etc?

We can confirm that the image is uploaded to file server successfully:

/data/clearml/data/fileserver/examples/register image.b8bd8c27aaa6416a9b870cdc3878a4f3/metrics/image/image PIL ll
total 12K
-rw-r--r-- 1 london london 12K Apr 25 10:16 'image_image PIL_00000000.jpeg'

For some reasons, the front-end could not grab/display the image

Interesting, if this is the issue, a simple sleep after reporting should prove it. Wdyt?
BTW are you using the latest package? What's your OS?

Hmm, might be, check if your files server is running and configured properly

Yes, artifacts (including both zip and folder) could be uploaded.

This issue is similar to the one on stackoverflow ( None ) and github ( None )
