pip install --upgrade --force --no-dependencies https://github.com/apple/tensorflow_macos/releases/download/v0.1alpha3/tensorflow_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl https://github.com/apple/tensorflow_macos/releases/download/v0.1alpha3/tensorflow_addons_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl

苹果官方（macos 12+安装方法, 2.5不行可以试试2.6）https://developer.apple.com/metal/tensorflow-plugin/
最全地址：https://github.com/apple/tensorflow_macos
系统版本：https://zhuanlan.zhihu.com/p/386164537
找不到tensorflow-macos或者metal的情况下，这样安装 https://developer.apple.com/forums/thread/683757

问题：

依赖冲突，可以带上参数：pip install tensorflow-macos --force --no-dependencies
AlreadyExistsError（tensorflow 2.6.0）：错误原因是因为tensorflow和keras版本不匹配，运行pip install keras==2.6.0 可解决问题
找不到各种方法，可以查看tensorflow 官方api: https://www.tensorflow.org/versions

卸载conda
