 > **TensorFlow2Paddle is not stable and lots of tensorflow operations are not supported yet**
 
 > **Only tested on vgg_16/resnet_v1_50/inception_v3 with is_training=False**
 
+> **Tensorflow2Paddle目前还处于开发状态中，只支持有限的TensorFlow Op**
+
+> **目前仅在vgg_16/resnet_v1_50/inception_v3上， is_training参数设为False的情况下通过无diff测试**

 **Notice：You can install PaddlePaddle and Tensorflow in different virtual environment since there's dependency conflict between PaddlePaddle and TensorFlow**
 
+**提示：运行Tensorflow2Paddle，依赖Tensorflow环境，目前经测试，Tensorflow与PaddlePaddle的安装彼此存在依赖冲突，因此建议将PaddlePaddle和Tensorflow分别安装在不同的虚拟环境中
