faster-rcnn 中训练自己的数据出现的错误

训练过程中错误

error 1：assert (boxes[:, 2] >= boxes[:, 0]).all()

error1 解决办法：
将py-faster-rcnn/lib/datasets/imdb.py中的相应代码改成如下代码即可：
    def append_flipped_images(self):        num_images = self.num_images        widths = [PIL.Image.open(self.image_path_at(i)).size[0]                  for i in xrange(num_images)]        for i in xrange(num_images):            boxes = self.roidb[i]['boxes'].copy()            oldx1 = boxes[:, 0].copy()            oldx2 = boxes[:, 2].copy()            boxes[:, 0] = widths[i] - oldx2 - 1            boxes[:, 2] = widths[i] - oldx1 - 1            for b in range(len(boxes)):                if boxes[b][2] < boxes[b][0]:                   boxes[b][0] = 0            assert (boxes[:, 2] >= boxes[:, 0]).all()

error2 解决办法：
删除fast-rcnn-master/data/cache/ 文件夹下的.pkl文件，或者改名备份，重新训练即可。
