在 Windows 中成功安装布局解析器后,出现以下操作系统错误。
使用的代码:
model = lp.Detectron2LayoutModel(config_path="lp://PubLayNet/mask_rcnn_X_101_32x8d_FPN_3x/config",
extra_config=["MODEL.ROI_HEADS.SCORE_THRESH_TEST", 0.8],
label_map={0: "Text", 1: "Title", 2: "List", 3:"Table", 4:"Figure"})
使用布局解析器,尝试从图像中提取内容。但是当我尝试在布局解析器中加载模型时,它失败并出现以下错误

不确定它是一种锁还是什么。
请帮忙
最佳答案
即使我也遇到了类似的错误。我在 Windows 中手动尝试了一些解决方法。
我以您的案例为例:OSError: [Errno 22] Invalid argument: 'C:\Users\vchinna/.torch/iopath_cache\s/nau5ut6zgthunil\config.yaml?dl=1.lock'
请遵循以下流程。
导航到 C:\Users\vchinna/.torch/iopath_cache\s/nau5ut6zgthunil\config.yaml 打开该 config.yaml 文件
向下滚动到权重:https://www.dropbox.com/s/h7th27jfv19rxiy/model_final.pth?dl=1应该在 265 行左右。
复制该链接并将其粘贴到您的浏览器中,将下载“model_final.pth”。将此文件复制到您所需的文件夹。
现在替换 WEIGHTS 的路径:your_desired_folder/model_final.pth
保存它并运行它有效的代码!
但是我认为在你这样做之前有一个小的解决办法(如果你还没有这样做) [iopath 解决方法][1]
