Dockerfile安装openvino和opencv，opencv不使用dockerfile构建后端/即

如何解决Dockerfile安装openvino和opencv，opencv不使用dockerfile构建后端/即

有一个项目已经可以单独在机器上工作了。现在，我尝试构建Dockerfile来自动执行安装。

该项目使用openvino和opencv。 Opencv不是来自openvino。我从源代码4.3.0使用opencv。

首先，我完全运行Dockerfile。当我运行python项目时，出现错误：

 layerOutputs = self.net.forward(self.ln) cv2.error: OpenCV(4.3.0-openvino) /opt/intel/openvino_2020.3.194/opencv/modules/dnn/src/dnn.cpp:1138: error: (-213:The function/feature is not implemented) Unknown backend identifier in function 'wrapMat'

我注意到了错误。它说没有后端标识符。

我通过注释Dockerfile中的opencv，openvino安装行来手动确定安装步骤。我以交互方式连接Docker容器。我手动运行安装命令。我的项目正在运作。

在那之后，我只评论opencv安装行。只需安装openvino，然后手动安装opencv。而且它再次起作用。因此，我决定搜索opencv构建文件。

现在让我们考虑两个容器。第一个容器完全由Dockerfile构建。它有一个错误。在opencv安装之前，第二个容器由Dockerfile构建。 Opencv安装是手工完成的。

我检查每个文件夹中的/ home / foo / opencv / build文件夹大小。

在第一个容器中，文件夹的大小为535652。在第二个容器中，文件夹的大小为542172。

我看到了区别。而且我进行了深入的搜索。

在每个容器中，我列出了具有大小的build文件夹的所有子目录。之后，我将它们复制为单独的txt文件，然后为它们运行diff命令。我看到文件夹不同：

diff first-container.txt second-container.txt

我注意到后端/文件夹不同。我运行python项目时出现的错误与之相关。

我不从Docker等待它。手动或Dockerfile有什么区别？

我的dockerfile：
