Hi! I am using the ModelCheckpoint callback from Tensorflow to save the best model. When the experiment finishes if I go on the server to Experiment > Artifacts > Output Model I can see the model and subsequently by clicking on it the weights. how can I retrieve the stored weights? I tried task.models['output'][0].get_local_copy() and task.models['output'][0].get_weights() but both return a None path.

Three options:
In your code: Task.init(..., output_uri='s3://.../'2. Configure a default output_uri to be used by all tasks: https://github.com/allegroai/clearml/blob/64042f6c4fdaaf15b6c5f816f2fbf50f89c313e2/docs/clearml.conf#L156
3. In the UI after you clone a Task under Execution tab, "output" "destination"

In all cases output_uri can be:
/mnt/share/folder (if you have a shared folder between all machines. http://trains-server:8081/ gs://bucket azure://bucket/

I mean what is the actual link?
File:// is a path to a file.
If your machine cannot access that path you get an error.
For example:
file:///home/user/file.bin
translates to /home/user/file.bin
If you do not have the file /home/user/file.bin on your machine you get an error.
GrievingTurkey78 make sense ?
Note that by default trains / clearml will not upload your weights file anywhere , only if you set "output_uri" to a specific location it will do that .

It’s file://

I just want to retrieve the weights on a script that tests models I have trained in the past

Makes sense! Then where would I have to add output_uri to save the weights?

Using the get_weights(True) I get ValueError: Could not retrieve a local copy of model weights <ID>, failed downloading <URL>

On the server through the command line?

I get the URL to the checkpoint/weights can I use this to download the weights?

I get the URL to the checkpoint/weights

Is it a valid URL ?
GrievingTurkey78 Do you have there http:// or is it file:// ?

On all Agents

Yes, that sounds like the issue, is the file actually there ?

Hi GrievingTurkey78
task.models['output'][-1] should return the last stored model.
What do you have under under task.models['output'][-1].url

For option 2 do I have to configure it on all agents or on the server?
