 ## ONNX Conversion Script
 
-To use `optimum-cli`, `ColPaliForRetrieval` in transformers should be mapped in `AutoModel`, but currently is not. So I just sticked to this script, which is based on the official [guide](https://huggingface.co/docs/optimum/en/exporters/onnx/usage_guides/contribute#exporting-the-model) from huggingface.
+Currently in [pull request](https://github.com/huggingface/optimum/pull/2251) (not merged yet).
+
+```bash
+optimum-cli export onnx --model vidore/colpali-v1.3-hf ./onnx_output --task feature-extraction --variant text --dtype fp16
+```
+
+For fp16, there's an issue with transformers that is not fixed for now, so please use script below.
 
 ```python
 from pathlib import Path
