Getting AttributeError: ‘Node’ object has no attribute ‘add_fabnet’

[Nagmat Nazarov]

Dear Community,

 

While doing iperf3 experiment (https://github.com/fabric-testbed/jupyter-examples/blob/master/fabric_examples/complex_recipes/iPerf3/iperf3.ipynb) , Getting “AttributeError: ‘Node’ object has no attribute ‘add_fabnet'” as shown in attachment. What may be the issue?

Kind regards,

Nagmat

Hello Nagmat,

Could you please share the output of the following command from a terminal window in JH container?

pip list | grep fabric

 

Thanks,

Komal

(base) fabric@jupyter-nagmat-40nevada-2eunr-2eedu:~/work/iperf$ pip list | grep fabric
fabric 3.1.0
fabric-credmgr-client 1.3.2
fabric-fim 1.3.0

fabric-orchestrator-client 1.3.0
fabrictestbed 1.3.1
fabrictestbed-extensions 1.3.3

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,

It worked after removing

fabrictestbed-extensions==1.3.3  from requirements.txt

Thanks!
