Installing the opencvlibrary from the repository worked for me.
Just both the following commands.
opencv从存储库安装库对我有用。只需以下两个命令。
sudo apt-get install opencv-data
sudo apt-get install libopencv-dev
After installing that it worked as before. Previously I had build opencvmyself. The one from the repository will work apparantely.
安装后它像以前一样工作。以前我已经建立了opencv自己。存储库中的一个将正常工作。

libjasper-dev is not available for Ubuntu 17.04.
libjasper-dev 不适用于 Ubuntu 17.04。
So you need to install the package from an earlier release. Try the following:
因此，您需要安装早期版本的软件包。请尝试以下操作：
echo "deb http://us.archive.ubuntu.com/ubuntu/ yakkety universe" | sudo tee -a /etc/apt/sources.list
This will add a new line to the sources.list file in /etc/apt. It will allow installation of packages from 16.10.
这将在 /etc/apt 中的 sources.list 文件中添加一个新行。它将允许从 16.10 安装软件包。
You should be able to install the missing package libjasper-dev now with the following commands:
您现在应该可以使用以下命令安装缺少的软件包 libjasper-dev：
sudo apt-get update
sudo apt-get install libjasper-dev
