存在 2 个版本的 python 时安装 COCOAPI

Question

我需要在我的 linux 机器上安装 Python 3.5 的 COCOAPI，但是当我执行“make”时，它会自动为 2.7 安装它。使用“make”时是否可以选择 python 版本？

编辑 1： 转到 PythonAPI 文件夹并通过 python3 setup.py install 安装它会出现以下错误。

sudo python3 setup.py install

我尝试安装 cython，然后安装 pycocotools，但这给了我以下错误。

要解决上述错误，请运行以下适当版本的 python。

sudo apt-get install python3.5-dev

然后执行以下操作：

pip3 install pycocotools --user

然后重新运行以下内容：

sudo python3 setup.py install

Answer 1

使用git clone https://github.com/cocodataset/cocoapi.git 克隆repo，然后输入它所在的目录并输入python3 setup.py install，它应该使用python3 安装。

如果上述方法不起作用，请尝试pip3 install cython 后跟pip3 install pycocotools（如果需要，您可以将--user 标志添加到所有这些）

Answer 2

您可以确保默认的python 解析为您感兴趣的那个，例如，将python 符号链接到python2，无论它被定义在哪里（可能是/usr/bin）
