本文记录了使用Faster-RCNN在CPU上训练自定义数据集时遇到的错误及解决办法，包括VOCdevkit2007文件夹缺失、Caffe配置、.pkl文件问题、代码错误等，并提供了相应的解决方案。

主要照这篇博客进行训练配置，因为没有GPU所以好多坑，CPU训练可以参见这篇博客

正所谓，跑通了的都一样，错误千万样。按照教程来也是坑多

训练：

 python train_faster_rcnn_alt_opt.py  --net_name ZF --weights /home/lys/py-faster-rcnn/data/imagenet_models/ZF.v2.caffemodel --cfg /home/lys/py-faster-rcnn/experiments/cfgs/faster_rcnn_alt_opt.yml  --imdb voc_2007_trainval

error1：

Cannot use GPU in CPU-only Caffe: check mode.

solution1：

把py-faster-rcnn/tools/下的所有py文件中的GPU注释掉，然后mode设为cpu。示例如下：

#    caffe.set_mode_gpu()
    caffe.set_mode_cpu()
#    if args.gpu_id is not None:
#        caffe.set_device(args.gpu_id)

error2：

solution2：

智障错误。只顾了查看trainval.txtz在不在了，没有创建VOCdevkit2007文件夹，直接就VOC2007了
