安装pycocotools时报错

安装pycocotools：

下载好安装包到本地（链接：https://github.com/cocodataset/cocoapi），进入cocoapi-master/PythonAPI/文件夹下执行make编译：

$ cd cocoapi-master/
$ cd PythonAPI/
$ make

报错：

解决：（python3.5）

1. 安装python3-dev

$ sudo apt-get install python3-dev

使用'sudo apt autoremove'来卸载它(它们)。
将会同时安装下列软件：
  libpython3-dev libpython3.5-dev python3.5-dev
下列【新】软件包将被安装：
  libpython3-dev libpython3.5-dev python3-dev python3.5-dev
升级了 0 个软件包，新安装了 4 个软件包，要卸载 0 个软件包，有 176 个软件包未被升级。
需要下载 37.7 MB 的归档。
