我试图通过设置一个新的蟒蛇环境并强迫它使用arm64构建在我的M1硅(macOS 12.4)上安装tensorflow:
CONDA_SUBDIR=osx-arm64 conda create -n=NAME python=3.9 -c conda-forge --override-channels
，然后按照开发人员的说明使用M1 GPU:
conda install -c apple tensorflow-deps
pip3 install tensorflow-macos
但是我得到了termcolor:
的错误Building wheel for termcolor (setup.py) ... error

通过添加pip3 install tensorflow-metal完成安装，然后在python3 shell中加载模块tensorflow会产生以下错误:

运行pip3 uninstall termcolor和pip3 install termcolor产生相同的安装错误。
我只是在这里迷路了，现在没有为termcolor构建的功能M1硅吗?还是我哪里搞砸了?
好的。问题出在pip:
conda uninstall termcolor
conda install termcolor
解决了所有问题，tensorflow似乎正在工作(手指交叉!)
请注意，tensorflow-macos目前只能通过pip安装，所以我首先需要让termcolor构建的pip失败，用conda删除它，然后重新安装。
