这种情况突然发生，我能够导入 cv2，但现在导入时出现“AttributeError：部分初始化的模块‘cv2’没有属性‘gapi_wip_gst_GStreamerPipeline’（很可能是由于循环导入）”错误。我尝试过的事情：

1-卸载并安装opencv。2-在cmd中，我输入“pip list”并列出了opencv-python包。我运行“python”命令并尝试导入 cv2 但出现相同的错误。请帮忙。

最近我在MacBook Pro(El Capitan 10.11.6)上安装了Microsoft R Open 3.3.1.当我打开RStudio或使用R控制台时,我收到以下警告消息:

Warning message:
In doTryCatch(return(expr), name, parentenv, handler) :
  unable to load shared object '/Library/Frameworks/R.framework/Resources/modules//R_X11.so':
  dlopen(/Library/Frameworks/R.framework/Resources/modules//R_X11.so, 6): Symbol not found: _CGBitmapContextCreate
  Referenced from: /Library/Frameworks/R.framework/Resources/modules//R_X11.so
  Expected in: flat namespace

您知道一种阻止打印消息(或解决问题)的方法吗？

谢谢!

我正在尝试构建一个 docker 映像，该映像将作为函数部署在 AWS Lambda 上。能够成功构建和测试图像，但当我尝试在函数中导入 OpenCV 时遇到问题。

当我从 app.py 中删除 import 语句时，我没有遇到这个问题

我面临的错误 -

{"errorMessage": "Unable to import module 'app': libGL.so.1: cannot open shared object file: No such file or directory", "errorType": "Runtime.ImportModuleError"}
