描述

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:
"$torch.load(__local_refs['arch_ckpt_path'], map_location=torch.device('cuda'))"

[2025-07-07 21:02:28,103] [19056] [MainThread] [ERROR] (uvicorn.error:59) - Application startup failed. Exiting.`

Here is my PyTorch version:
Name: torch Version: 2.7.1+cu128 Summary: Tensors and Dynamic neural networks in Python with strong GPU acceleration Home-page: https://pytorch.org/ Author: PyTorch Team Author-email: packages@pytorch.org License: BSD-3-Clause Location: d:\anaconda\envs\monailabel\lib\site-packages Requires: filelock, fsspec, jinja2, networkx, sympy, typing-extensions Required-by: lpips, monai, pytorch-ignite, sam2, torchaudio, torchio, torchvision

Could you please advise me on how to properly resolve this issue?

Thank you very much for your time and help!

打开贡献指南

从这里开始

  1. 先读完整个 Issue,再读项目的贡献指南。
  2. 在 Issue 下留言说明你要接手 —— 这能避免两个人做同样的事。
  3. Fork 仓库,在一个分支上完成修改。
  4. 提交 Pull Request,并在描述里引用这个 Issue 编号。

调研方向

首先,使用 PyTorch 2.7.1 复现报告中的 monailabel start_server 命令,并检查错误中的 torch.load 表达式。确认 checkpoint 加载行为是否由报告的 PyTorch 版本导致,并将完成定义为一种有文档记录或经过验证的、能够在不出现此错误的情况下启动应用程序的方式。
