在 Ubuntu 18.04,我成功安装了 openalpr 并对其进行了测试。现在我想用python来调用它。为此,我安装了https://pypi.org/project/openalpr/
pip install openalpr
但是我遇到了路径问题,示例中的路径不起作用。
alpr = Alpr("eu", "/etc/openalpr/openalpr.conf", "/usr/share/openalpr/runtime_data")
我收到一个错误
>>> from openalpr import Alpr
>>> alpr = Alpr("eu", "/etc/openalpr/openalpr.conf", "/usr/share/openalpr/runtime_data")
