4.Since py-faster-rcnn does not support multiple training datasets, we need to merge VOC 2007 data and VOC 2012 data manually. Just make a new directory named VOC0712, put all subfolders except ImageSets in VOC2007 and VOC2012 into VOC0712(you'll merge some folders). I provide a merged-version ImageSets folder for you, please put it into VOCdevkit/VOC0712/. when i follow this step and marged with provided Imageset than i got this error

but if i use the Imageset from VOC2007 than after finish all ite i got this error,does anyone face same problem?

I have the same error, I just mkdir -p /home/user01/Music/fc/py-R-FCN/data/VOCdevkit0712/results/VOC0712/Main/ ,and retrain .

[macqueen09]

same question , and I fond that I change my PascalVOC2007 to PascalVOC0712 and I forget to change "/home/user01/Music/fc/py-R-FCN/data/VOCdevkit2007" to "VOCdeviket0712". now I'm retest again. (we needn't to retrain)
