Sorry, for not indicating this before, you can restart the container from File -> Hub Control Panel -> Stop My Server, then logout and login.

Could you please remove the entries for fabrictestbed-extensions from ~/work/fabric_config/requirements.txt and restart your container? Please try your notebooks after the restart.

Thanks,

Hello Acheme,

Could you please share the output of the following commands? Also, which container are you using?

cat ~/work/fabric_config/requirements.txt

Thanks,

Hello Thushari,

We are looking into this and have found that in a race condition when list_resources times out, you may observe the output as shared by you. We are debugging this and would work on a fix. In the meanwhile, could you please explicitly pass a site name when adding a node to your slice and try it?

Also, please try both 1.4.6 and 1.5.1 containers and let us know if it works for any of the options.

Thanks,

Komal

It looks like an older version of fablib is running in your container. Could you please ensure that there are no entries for fabrictestbed-extensions in fabric_config/requirements.txt ? Please restart your JH container after that and try the notebook again.

Versions should something like below for 1.4.6 and 1.5.1 container options.

For 1.4.6 container:

pip list | grep fabric
fabric 3.1.0
fabric-credmgr-client 1.3.2
fabric-fim 1.4.14
fabric-fss-utils 1.4.0
fabric-orchestrator-client 1.4.7
fabrictestbed 1.4.7
fabrictestbed-extensions 1.4.6


For 1.5.1 container:


$ pip list | grep fabric
fabric 3.1.0
fabric-credmgr-client 1.5.0
fabric_fim 1.5.2
fabric_fss_utils 1.5.0
fabric-orchestrator-client 1.5.1
fabrictestbed 1.5.1
fabrictestbed-extensions 1.5.1


 

Thanks,

Hello,

Could you please ensure that configure_environment.ipynb notebook has been executed and your environment is setup? Also, please remove any entries for fabrictestbed-extensions you may have in fabric_config/requirements.txt and restart your container and attempt creating the slice again?

Thanks,

Hi Nagmat,

Could you please check if your bastion keys are still valid? Also, could you please share and check for errors in /tmp/fabric/fablib.log ?

Thanks,

Hi Nagmat,

I don’t see any failures for this slice either. It seems like this slice was deleted on 2023-05-16 17:31:42 UTC.

However, I do see that, another slice created by you yesterday failed with “Insufficient resources error” which would explain the notebook behavior.

Reservation ID: fb7939b5-8f8b-4517-a975-3da648a190c3 Slice ID: 55c64491-4edc-44cc-885f-264f9fa4cbc2

Hi Nagmat,

Could you please share slice id for the slice(s) if possible? Also, you could check in Portal under Experiment->Slices, please select “Include Dead/Closing” slices. Any errors that occurred in those slices should be displayed when you view the slice on the portal.

Thanks,
Komal
