Mac M1开发环境配置---tensorflow

Posted 2022-08-06 海里的鱼2022

1. 安装conda环境， miniconda

这里采用的Miniconda（精简版Anaconda）下载地址：Miniconda — Conda documentation 

安装完成后，需要运行～/.bash_profile, 路径设置才能起作用

2. 建立python虚拟开发环境

可以python3.8或者3.9

我们这里用的3.9

conda create -n py39tf python=3.9 

3. 安装tensorflow包支持

 

conda install -c apple tensorflow-deps # Step 1: Environment setup Install the TensorFlow dependencies: 
pip install tensorflow-macos # Step 2: Install base TensorFlow 
pip install tensorflow-metal # Step 3: Install tensorflow-metal plugin

4. 环境测试验证

WARNING:tensorflow:From <stdin>:1: is_gpu_available (from tensorflow.python.framework.test_util) is deprecated and will be removed in a future version.
Instructions for updating:
Use `tf.config.list_physical_devices('GPU')` instead.
Metal device set to: Apple M1

 搞定。
