OpenCV错误：重塑时图像步骤错误

Question

  

可能重复：
  Getting OpenCV Error “Image step is wrong” in Fisherfaces.train() method

我正在尝试运行此示例here。

我在Eclipse中运行代码。我正确地构建了项目，但是当我从提示符运行.exe文件时出现此错误：

OpenCV Error: image step is wrong (the matrix is not continuous, thus its number of rows can not be changed) in reshape, file: C:/slave/WinInstallerMegaPack/src/opencv/modules/core/src/matrix.cpp, line 801
terminate called after throwing an instance of 'cv::Exception'
 what(): C:/slave/WinInstallerMegaPack/src/opencv/modules/core/src/matrix.cpp:801:error: (-13) The matrix is not continuous, thus its number of rows can not be changed in function reshape

我该如何解决？我在Windows 7 64位操作系统上使用OpenCV-2.4.3。任何人都可以帮助我吗？ 非常感谢你。
