如果您想使用Pascal Context数据集，请安装Detail，然后运行以下命令将注释转换为正确的格式。

1.安装Detail

进入项目终端

#即 这是在我自己的项目下直接进行克隆操作：
git clone https://github.com/zhanghang1989/detail-api.git $PASCAL_CTX
# 获得detail_api

若是出现下面的问题可以手动下载detail-api的压缩包文件到项目中，再进行解压.

我的就是git时候出了问题，然后手动下载的，服务器有时候也不稳定。

5、进行detail_api文件夹的PythonAPI中

cd 你的路径/PythonAPI

然后python setup.py install

可能没有Cython

直接用pip install Cython

再跑python setup.py install

2.格式转换

Pascal Context的训练和验证集可以从这里下

要从原始数据集中分离训练和验证集，您可以从此处下载trainval_merged. json。下载链接https://codalabuser.blob.core.windows.net/public/trainval_merged.json

python tools/convert_datasets/pascal_context.py data/VOCdevkit data/VOCdevkit/VOC2010/trainval_merged.json

其中pascal_context.py如下

已经在转换啦，慢慢等待就好，可以干点其他的，或者浅休息一下。
