python - 无法使用 pip 安装新的 tflite-support

问题描述

按照这个链接，我一直在尝试tflite-support使用 pip 安装模块。我收到以下错误：

ERROR: Command errored out with exit status 1:

有什么线索吗？我知道以前有人问过类似的问题，但这些答案没有运气

解决方案

将评论变成答案：

这看起来像是setuptools. 降级到41：

$ pip install --upgrade 'setuptools<42'

现在（理想情况下）预安装pybind11以避免在构建tflite-support轮子时丢失标题：

$ pip install 'pybind11>=2.4'

现在安装tflite-support应该成功，没有任何中间错误：

$ pip install tflite-support
