+You can also check if your LoRA is correctly mounted [here](tests/test_lora_inference.py).
+
 **Note:** For Image-to-Video finetuning, you must install diffusers from [this](https://github.com/huggingface/diffusers/pull/9482) branch (which adds lora loading support in CogVideoX image-to-video) until it is merged.
 
 Below we provide additional sections detailing on more options explored in this repository. They all attempt to make fine-tuning for video models as accessible as possible by reducing memory requirements as much as possible.

+你也可以在[这里](tests/test_lora_inference.py)来检查你的Lora是否正常挂载。

 **注意：** 对于图像到视频的微调，您必须从 [这个分支](https://github.com/huggingface/diffusers/pull/9482) 安装
 diffusers（该分支为 CogVideoX 的图像到视频添加了 LoRA 加载支持）直到它被合并。
