AttributeError: /usr/lib/libopenalpr.so.2: undefined symbol: openalpr_add_encoded_image_to_batch

Could you provide code you run? Not just error.
Because this error says that you did not provide needed attributes to alpr command

class Alpr: Set self.loaded to False before exception
b352e75 
There are currently [46 open issues related to `loaded`](https://github.com/openalpr/openalpr/search?p=2&q=loaded&type=issues).  Many of these [`AttributeError` issues](https://github.com/openalpr/openalpr/search?q=AttributeError&type=issues) are caused because `self.loaded` is only defined at the end of this method on (line 117).  If an exception is raised (like line 62, etc.) then `self.loaded` is _never_ defined so subsequent code fails when trying to determine if `Alpr` has successfully loaded.
