from label_studio_sdk.label_interface.objects import PredictionValue fails

[kvkamal]

Describe the bug After installing label studio version 1.13.1, unable to start ml backend using command:

label-studio-ml start --debug mycustom_ml_backend

fails when executing: from label_studio_sdk.label_interface.objects import PredictionValue when running label-studio-ml-backem/label_studio_ml/response.py

To Reproduce Try running any custom ml backend that needs to run response.py

Expected behavior used to work in 1.12 Screenshots Traceback (most recent call last): File "", line 198, in _run_module_as_main File "", line 88, in _run_code File "C:\path\to\new\virtual\environment\Scripts\label-studio-ml.exe__main__.py", line 4, in File "C:\path\to\new\virtual\environment\Lib\site-packages\label_studio_ml\server.py", line 13, in from .model import get_all_classes_inherited_LabelStudioMLBase File "C:\path\to\new\virtual\environment\Lib\site-packages\label_studio_ml\model.py", line 28, in from .response import ModelResponse File "C:\path\to\new\virtual\environment\Lib\site-packages\label_studio_ml\response.py", line 5, in from label_studio_sdk.objects import PredictionValue ModuleNotFoundError: No module named 'label_studio_sdk.objects' Press any key to continue . . .

Environment (please complete the following information):

• OS: Windows Server 2022 Datacenter
• Label Studio Version [1.13.1]
• (used to work in v1.12)

Additional context tried installing 1.13.1 because of #6291 when using v1.12.1 . Currently work stalled because I'm unable to use ml backend.

Hi @kvkamal,

Could you pull the latest version of the ML backend? This was fixed in https://github.com/HumanSignal/label-studio-ml-backend/commit/bdfc42b68a0a7e5dd0eeb328d27457b71eec6540#diff-89ce0fb4c09d2e5133f5924a8b373dad7d7145cb555a16b444d39b0b25d2031c

ML backend works fine after reinstalling latest backend. Thanks.
