Perhaps you could elaborate on the inputs used in the tool at the time the error occurred

@jackyji This error can happen when you don’t input entire exported folder but only point to the image folder. 

The Export Training Data for Deep Learning tool typically outputs a folder containing something like the following

In this case, the input to the Train Deep Learning Model tool is: "FormatTest_PNG_KITTI_rectangles" folder
