+# Draft training codes
+
+We provde the draft training codes here. Unfortunately, data preprocessing code is still being reorganized.
+
+## Data preprocessing
+ You could refer the inference codes which [crop the face images](https://github.com/TMElyralab/MuseTalk/blob/main/scripts/inference.py#L79) and [extract audio features](https://github.com/TMElyralab/MuseTalk/blob/main/scripts/inference.py#L69).
+
+Finally, the data should be organized as follows:
+```
+./data/
+├── images
+│     └──RD_Radio10_000
+│         └── 0.png
+│         └── 1.png
+│         └── xxx.png
+│     └──RD_Radio11_000
+│         └── 0.png
+│         └── 1.png
+│         └── xxx.png
+├── audios
+│     └──RD_Radio10_000
+│         └── 0.npy
+│         └── 1.npy
+│         └── xxx.npy
+│     └──RD_Radio11_000
+│         └── 0.npy
+│         └── 1.npy
+│         └── xxx.npy
+```
+
+## Training
+Simply run after preparing the preprocessed data
+```
+sh train.sh
+```
