 #### 本地Anaconda安装
 
+温馨提示：**在搭载Apple芯片的MacBook上必须使用TensorFlow 2.5或更高版本**。
+
 Demo实验中使用的环境为 `python=3.6.8` + `tenserflow=1.12.0`
 
 ```bash
 conda create -n py36_tf12 python=3.6.8
 conda activate py36_tf12
 pip install tensorflow==1.12.0
+pip install tensorflow_probability==0.5.0
 ```
 
+注意：必须要安装`tensorflow_probability`包，需要根据tensorflow的版本安装对应版本的`tensorflow_robability`包。
+
+常见版本对应关系：
+
+| TensorFlow版本 | TensorFlowProbability版本 |
+|--------------|-------------------------|
+| 1.12         | 0.5.0                   |
