Win 10 安裝Pycocotools發生錯誤的解決方法－張郎生活的筆記

Mask RCNN教學的YOUTUBE在https://www.youtube.com/watch?v=2TikTv6PWDw

在試驗網路上的教學時, 在安裝步驟這裡卡住了

當我輸入pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI

發生了這樣的錯誤

大概就是這一串....................

網路上的文章說原因出在Pycocotools不支持Windows......

還好最後解決了, 方法在下面的連結

https://github.com/philferriere/cocoapi

首先下載 Visual C++ 2015 build tools 並且安裝

https://go.microsoft.com/fwlink/?LinkId=691126

接著輸入pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI
