从github仓库安装轮子文件时出错(下载pycocotools)

Question

我正在安装Tensorflow (1.15.0)，以便执行一些深度学习对象检测，但在安装pycocotools时遇到问题。我正在关注this教程，这是一个来自YouTube频道Sentdex的更新教程。为此，我也使用了Anaconda提示符。

在创建并激活conda环境并安装所有需要的包(TensorFlow、lxml等)之后，我尝试运行命令pip install pycocotools包，但得到以下错误：

显然，需要从PythonAPI子目录下的this github存储库下载一个轮子文件。我运行这段代码来做到这一点：

pip install git+https://github.com/philferriere/cocoapi#egg=pycocotools^subdirectory==PythonAPI

会产生以下错误：

Collecting pycocotoolssubdirectory==PythonAPI

如何成功安装此存储库？我需要这个轮子文件，这样我才能继续安装pycocotools。注意:我已经安装了最新版本的pip，所以这不是问题所在。

Answer 1

尝试运行它，如下所示：

pip install pycocotools-windows

如建议的here。
