Descripción
Hello, thank you very much for your great work on MONAI Label.
When I tried to run the following command:
monailabel start_server --app apps/monaibundle --studies datasets/venous_liver --conf models pancreas_ct_dints_segmentation
I encountered this error:
File "D:\anaconda\envs\monailabel\lib\site-packages\monai\bundle\config_item.py", line 374, in evaluate return eval(value[len(self.prefix) :], globals_, locals) File "<string>", line 1, in <module> File "D:\anaconda\envs\monailabel\lib\site-packages\torch\serialization.py", line 1524, in load raise pickle.UnpicklingError(_get_wo_message(str(e))) from None _pickle.UnpicklingError: Weights only load failed. This file can still be loaded, to do so you have two options, do those steps only if you trust the source of the checkpoint. (1) In PyTorch 2.6, we changed the default value of the weights_onlyargument intorch.loadfromFalsetoTrue. Re-running torch.loadwithweights_onlyset toFalsewill likely succeed, but it can result in arbitrary code execution. Do it only if you got the file from a trusted source. (2) Alternatively, to load withweights_only=Trueplease check the recommended steps in the following error message. WeightsUnpickler error: Unsupported global: GLOBAL numpy.core.multiarray._reconstruct was not an allowed global by default. Please usetorch.serialization.add_safe_globals([numpy.core.multiarray._reconstruct])or thetorch.serialization.safe_globals([numpy.core.multiarray._reconstruct])context manager to allowlist this global if you trust this class/function.
`RuntimeError: Failed to evaluate ConfigExpression:

Here is my PyTorch version:

Could you please advise me on how to properly resolve this issue?
Thank you very much for your time and help!

Línea de trabajo
Comienza reproduciendo el comando monailabel start_server reportado con PyTorch 2.7.1 e inspecciona la expresión torch.load del error. Confirma si el comportamiento de carga del checkpoint se debe a la versión de PyTorch reportada y define la finalización como una forma documentada o verificada de iniciar la aplicación sin este error.
