Issues running the examples of client-python bindings

[Miguel Figueiredo Nunes]

Hello!

I'm trying to get myself more familiar with the python bindings, but I'm stuck when running the example offered in the repo:

The error it's quite long, so I'll only post the most relevant part. If necessary, I can provide the whole stack:

 'items': [],
 'kind': 'VirtualMachineList',
 'metadata': {'_continue': '',
              'remaining_item_count': None,

              'self_link': None}}

AttributeError: module 'kubevirt.models' has no attribute 'K8sIoApimachineryPkgApiResourceQuantity'

I couldn't see this attribute in the docs or mentioned anywhere else. What I could be missing here?

Any help appreciated!

Best,

Hi Miguel,

I can't help with the specific issue but we had previously identified this repo as largely unmaintained. We put a call out for maintainers but only one person was interested IIRC and the conversation stalled. 
It likely should have been archived but looks it escaped our process due to it's automatic updates by KubeVirt bot. I'll look at fixing that next week so as to prevent others running into issues. Apologies for any wasted time on this. 

From the previous thread I believe there was a suggestion that you could use the following wrapper, which is maintained by Red Hat for their OpenShift QE: https://github.com/RedHatQE/openshift-python-wrapper/
I believe it should be compatible with KubeVirt. Maybe someone else knows of another option?

Thanks,
Andrew

Hi Andrew,

Thanks for the explanation and suggestions.

I gave a quick peek at the example code and seems quite straightforward.

Thanks for the help!

Best,
