+从v2环境迁移至v3
+
+Use v3 from v2 environment: 
+
+1. 需要pip安装requirements.txt更新环境
+
+2. 需要克隆github上的最新代码
+
+3. 从[huggingface](https://huggingface.co/lj1995/GPT-SoVITS/tree/main)下载这些v3新增预训练模型 (s1v3.ckpt, s2Gv3.pth and models--nvidia--bigvgan_v2_24khz_100band_256x folder)将他们放到`GPT_SoVITS\pretrained_models`目录下

+    如果想用音频超分功能缓解v3模型生成24k音频觉得闷的问题，需要下载额外的模型参数，参考[how to download](./tools/AP_BWE_main/24kto48k/readme.txt)
