1. pytorch3d安装不成功\
下载源码编译
```bash
python setup.py install
```
2. websocket连接报错\
修改python/site-packages/flask\_sockets.py
```python
self . url_map . add ( Rule ( rule , endpoint = f )) 改成
self . url_map . add ( Rule ( rule , endpoint = f , websocket = True ))
```
3. protobuf版本过高
```bash
pip install protobuf == 3.20.1
```
4. 数字人不眨眼\
训练模型时添加如下步骤
> Obtain AU45 for eyes blinking.\
> Run FeatureExtraction in OpenFace, rename and move the output CSV file to data/\<ID>/au.csv.
将au.csv拷到本项目的data目录下
5. 数字人添加背景图片
```bash
```
6. 用自己训练的模型报错维度不匹配\
训练模型时用wav2vec提取音频特征
```bash
100000 --asr_model cpierse/wav2vec2-large-xlsr-53-esperanto
```
7. rtmp推流时ffmpeg版本不对
网上版友反馈是需要4.2.2版本。我也不确定具体哪些版本不行。原则是运行一下ffmpeg， ，
```
```
8. 替换自己训练的模型
```python
.
├── data
│ ├── data_kf . json （ 对应训练数据中的transforms_train . json ）
│ ├── au . csv
│ ├── pretrained
│ └── └── ngp_kf . pth （ 对应训练后的模型ngp_ep00xx . pth ）
```
