### Create a model from a vision encoder model and a text decoder model
Next, we create a [VisionTextDualEncoderModel](https://huggingface.co/docs/transformers/model_doc/vision-text-dual-encoder#visiontextdualencoder).
The `VisionTextDualEncoderModel` class let's you load any vision and text encoder model to create a dual encoder.

Some datasets, like [`scene_parse_150`](https://huggingface.co/datasets/scene_parse_150), contain a "background" label that is not part of the classes. The Scene Parse 150 dataset for instance contains labels between 0 and 150, with 0 being the background class, and 1 to 150 being actual class names (like "tree", "person", etc.). For these kind of datasets, one replaces the background label (0) by 255, which is the `ignore_index` of the PyTorch model's loss function, and reduces all labels by 1. This way, the `labels` are PyTorch tensors containing values between 0 and 149, and 255 for all background/padding.
In case you're training on such a dataset, make sure to set the ``reduce_labels`` flag, which will take care of this.
