pycocotools - “需要 Microsoft Visual C++ 14.0 或更高版本”虽然已安装

Question

I want to install the TensorFlow object detection API, for that, I need the pycocotools package, which is reliant on Visual Studio C++ Build Tools v14 or higher.

I have both tried to install the full Visual Studio 2022, as well as the Visual Studio build tools 2019 separately. No matter what I do, this is my error message:

Building wheel for pycocotools (setup.py) ... error

  ERROR: Failed building wheel for pycocotools

I am on a Windows 11 machine with Anaconda3 2021.11 (Python 3.9.7 64-bit) installed.

My installation details inside Visual Studio installer look like this .

Help is much appreciated.

I believe you are missing MSBuild. You can add it from visual studio installer.
