If I understand correctly, you would like to include text-only datasets when training multimodal models?

Please have a look at #402, which has a big impact on this PR. In there I forward the dataset requirements from the model to the dataset. Currently a text-only dataset will cause a crash, but I could adjust to create empty image patches instead, and it would make more sense than doing it in the model. What do you think?

[jlamypoirier]

This should probably go in preprocessing/image_patch. Also it's very similar to ImagePatchConfig.get_patches_from_images, maybe it can be reused.

Hey thanks @jlamypoirier ! Yeh, this is about using test-only data for multimodal model. Are you planing to address it in #402? I am fine with creating those in the dataset instead of the model

[jlamypoirier]

I'll add it myself, it's not much effort and will affect the PR
