Unable to create slices.

[Hapuarachchige Thushari Hapuarachchi]

Hello,

When I am trying to create a slice using the command given in ‘hello_fabric.ipynb’ (version 1.4.6.), I am getting the following error.

–> 197 assert site is not None
198 # make sure name is unique within the topology
199 if name in self._list_nodes().keys():

(Please find the attachment)

I was able to create slices successfully last week.

However, in fablib.log, I found the following error;

[22:04:32] {/opt/conda/lib/python3.9/site-packages/ipykernel/comm/manager.py:46} ERROR – No such comm target registered: jupyter.widget.control

Thank you for your time.

Best regards,

Thushari

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,

Komal

Hello Komal,

Thank you very much for your suggestions. I tried all those steps but I am still getting the same error.

The site list is also not visible as usual. (See the screenshot)

Thanks,

Thushari

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

Hello Komal,

I tried 1.5.1 container and it worked. I am able to create slices.

Thanks a lot for your time and help.

Best regards,

Thushari
