Issue with data generation

[amoghskanda]

Hey, thanks for making this open source. Despite choosing the start and arrival lane, no images/videos are being generated for that respective lane. Some lanes are giving key errors while there's a constant error in the terminal that reads :

drawVex = [QPointF(ctf.zoomScale*(ctf.drawCenter+rev[0]+ctf.offset[0]),ctf.zoomScale*(ctf.drawCenter-rev[1]+ctf.offset[1])) for rev in relativeVex]
SystemError: <class 'DeprecationWarning'> returned a result with an error set

This is happening in OASim/limsim/simModel/common/carFactory.py

Update : Had to specify the frames in/hmi/dataGenerator/data_generator.py line 113. I loaded the egoTrackingTest.db and it had 5 frames of data.

Error: Answered with error to command 0xc4: Vehicle '0' is not known

This error keeps getting displayed on the terminal. I'm guessing it's an issue with typecasting string vehicle id into integer somewhere. @jiahao68 can you look into it once?
