+## Config
+Note that currently our model loading for vae and diffusion model supports two types:
+
+* load from local file path
+* load from huggingface
+
+Our config supports loading from huggingface by default.
+If you wish to load from a local path, you need to set `force_huggingface=True`, for instance:
+
+```python
+# for vae
+vae = dict(
+    type="OpenSoraVAE_V1_2",
+    from_pretrained="/root/commonData/OpenSora-VAE-v1.2",
+    micro_frame_size=17,
+    micro_batch_size=4,
+    force_huggingface=True, # NOTE: set here
+)
+# for diffusion model
+model = dict(
+    type="STDiT3-XL/2",
+    from_pretrained="/root/commonData/OpenSora-STDiT-v3",
+    qk_norm=True,
+    enable_flash_attn=True,
+    enable_layernorm_kernel=True,
+    force_huggingface=True, # NOTE: set here
+)
+```
+
 ## Inference
 
 You can modify corresponding config files to change the inference settings. See more details [here](/docs/structure.md#inference-config-demos).
