Kitty to Darknet issue #149

Open DanIn232 opened 4 years ago

DanIn232 commented 4 years ago

Hi,

Thank you for writing this very useful piece of code. I have been trying to convert Kitty annotations to Darknet ones, and I'm having an issue with it. this is the input:

cvdata_convert --in_format kitti --out_format darknet --annotations_dir old --images_dir old --out_dir new

error: TypeError: join() argument must be str or bytes, not 'NoneType'

Any idea what's wrong?

Thanks

Yes, it looks like the KITTI files are missing fields (column values) in one or more of the records (rows), and so when it's trying to perform a join it's failing because the missing field(s) result in a None, and you can't join to a None (or NoneType). That's one conjecture, anyway. :)

If you can provide your input file(s) and as much about what you're trying to do here I may be able to get to the specific issue where this is happening, otherwise I can only speculate. Also, I apologize in advance because I don't have too much time to devote to this project currently, so it may take a little while...
