cv_bridge broken in Groovy

[pirobot]

When I run the first cv_bridge Python example on the ROS Wiki, I get the following error repeated over and over:

[ERROR] [WallTime: 1357692371.463472] bad callback: <bound method image_converter.callback of <__main__.image_converter instance at 0xac1378c>>
Traceback (most recent call last):

    return eval("cv.CV_%s" % encoding)
  File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute 'CV_yuv422'

I get the same error when trying to use cv_bridge in any of my own existing code--code that runs fine under both Electric and Fuerte.

thx for reporting the error, I did have it too. 1.10.1 fixes it for me. Please reopen if that is still problematic,

Thanks Vincent! Works for me too now.

I am experiencing this same error for the same tutorial in fuerte. How do I fix?

[vrabaud]

Fuerte is not supported anymore, I'm sorry. It was a bug back then too. You can patch your code with the commit above. I would strongly suggest to move to Indigo, it's a release supported for 5 years.

Thanks for clearing that up.
