运行faster-rcnn/pytorch/jwyang版本出现的错误

参考：

1. github https://github.com/jwyang/faster-rcnn.pytorch/tree/pytorch-1.0

2. 运行方法 https://www.cnblogs.com/wind-chaser/p/11359521.html 作者 wind-chaser （如版权声明形式不规范我会及时更改的！！）

 

问题：

Q1： torch.utils.ffi is deprecated. Please use cpp extensions instead.

着实忘了具体看的哪一篇issue……

在faster-rcnn pytorch-1.0分支下不需编译make.sh文件

Q2：importError: cannot import name '_mask'?Executed python setup.py build develop 

运行CUDA_VISIBLE_DEVICES=$GPU_ID python trainval_net.py \
>                    --dataset pascal_voc --net vgg16 \
>                    --bs $BATCH_SIZE --nw $WORKER_NUMBER \
>                    --lr $LEARNING_RATE --lr_decay_step $DECAY_STEP \
>                    --cuda

出现error：

解决方案：
reinstall coco api
link：https://github.com/cocodataset/cocoapi
issue from ：https://github.com/jwyang/faster-rcnn.pytorch/issues/410

cd data

git clone https://github.com/pdollar/coco.git 

cd coco/PythonAPI

make

cd ../../..

Q3: cannot import name 'imread' from 'scipy.misc' 

切换scipy版本到1.2.
