Example 4.2 error when launching Blob tracking with OpenCV and Python part 2,

i get this error when Launching

Invalid roslaunch XML syntax: not well-formed (invalid token): line 1, column 1
The traceback for the exception was written to the log file

Can i get a little bit of more information. Do i need to make a new launch file or can i launch the py file. I tried with the example given in solution.

Hi Vedkar,

It is a syntax error in your XML. make sure you are closed all brackets.

Best Regards,

The my_blob_tracking_pkg package

The error is the .launch file. Can you paste that here?
