+## Error Loading MUD Model File: *****.cvimodel not exists, load model failed
+
+* Check if the .mud file you are trying to load really exists on the device (note, it should be on the device, not on the computer, it needs to be transferred to the device).
+* Verify that the model path you wrote is correct.
+* If you have changed the file name, note that the MUD file is a model description file and can be edited with a text editor. The actual model file is the .cvimodel file (for MaixCAM). The .mud file specifies the file name and path of the .cvimodel. Therefore, if you have changed the file name of `.cvimodel`, you also need to modify the `model` path in the `.mud` file. For example, here is the mud file for the Yolov5 model:
+```ini
+[basic]
+type = cvimodel
+model = yolov5s_224_int8.cvimodel
+
+[extra]
+model_type = yolov5
+input_type = rgb

+```
+Here, the `model` is specified as the `yolov5s_224_int8.cvimodel` file relative to the directory of this `.mud` file. If you have changed `yolov5s_224_int8.cvimodel` to another name, you need to update it here as well.

+## 加载 MUD 模型文件报错 *****.cvimodel not exists， load model failed
+
+* 检查设备中（注意不是电脑里面，需要传到设备里面去）是否真的存在你加载的 .mud 文件。
+* 检查你写的模型路径写错没有。
+* 如果你改过文件名，需要注意： MUD 文件是一个模型描述文件，可以用文本编辑器编辑，实际的模型文件是 .cvimodel 文件（对于MaixCAM)，.mud 文件中指定了 .cvimodel 的文件名和路径，所以如果你改动了 `.cvimodel`的文件名，那么也要修改`.mud`文件中的`model`路径，比如这里 Yolov5 模型的 mud：
+```ini
+[basic]
+type = cvimodel
+model = yolov5s_224_int8.cvimodel
+
+[extra]
+model_type = yolov5

+这里制定了 `model` 为相对这个`.mud`文件目录的 `yolov5s_224_int8.cvimodel` 文件为模型文件，如果你改了`yolov5s_224_int8.cvimodel` 为其它名，那也需要改这里。
