source ~/enter/bin/activate

执行完之后，环境改变，终端显示当前环境

(base) xxMacBook-Pro ~ % conda --version
conda 22.9.0

创建一个conda环境

conda create -n tf python==3.9

切换到新环境

conda activate tf

(base) xxMacBook-Pro ~ % conda activate tf
(tf) xxMacBook-Pro ~ % 

安装tensorflow

在新环境下使用命令，每次使用TensorFlow的时候都需要激活conda环境

// 从Apple的仓库安装tensorflow的依赖
conda install -c apple tensorflow-deps

// 安装MacOS版本的TensorFlow
python -m pip install tensorflow-macos

// 安装tensorflow-metal，使TensorFlow支持GPU计算
python -m pip install tensorflow-metal

conda环境激活后,可以测试

(base) xx@xxMacBook-Pro ~ % conda activate tf
(tf) xx@xxMacBook-Pro ~ % python           
Python 3.9.0 | packaged by conda-forge | (default, Nov 26 2020, 07:55:15) 
[Clang 11.0.0 ] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow as tf
>>> print(tf.__version__)
2.11.0
>>> 

关闭tensorflow环境

conda deactivate

pycharm配置

创建项目

PyCharm菜单，进入Preferences菜单，选择对于的项目的选项Project Interpreter

查询tf环境使用的python

(tf) xxMacBook-Pro ~ % which python                          
/Users/xxx/enter/envs/tf/bin/python

找到对应路径下的python，选中即可

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))

// 'Hello, TensorFlow!'
