I got `RuntimeError: Error(s) in loading state_dict for SAM2Base` when loading the new SAM 2.1 checkpoints
</summary>
<br/>
This is likely because you have installed a previous version of this repo, which doesn't have the new modules to support the SAM 2.1 checkpoints yet. Please try the following steps:
1. pull the latest code from the `main` branch of this repo
2. run `pip uninstall -y SAM-2` to uninstall any previous installations
3. then install the latest repo again using `pip install -e ".[notebooks]"`
In case the steps above still don't resolve the error, please try running in your Python environment the following
```python
from sam2.modeling import sam2_base
print(sam2_base.__file__)
```
and check whether the content in the printed local path of `sam2/modeling/sam2_base.py` matches the latest one in https://github.com/facebookresearch/segment-anything-2/blob/main/sam2/modeling/sam2_base.py (e.g. whether your local file has `no_obj_embed_spatial`) to indentify if you're still using a previous installation.
