FlaxVisionEncoderDecoderModel decoder_start_token_id
Im following the documentation here to instantiate a FlaxVisionEncoderDecoderModel but am unable to do so.I’m on Transformers 4.15.0https://huggingface.co/docs/transformers/master/model_doc/visionencoderdecoder#transformers.FlaxVisionEncoderDecoderModelfrom transformers import FlaxVisionEncoderDecoderModel, ViTFeatureExtractor, GPT2Tokenizer
from PIL import Image
import requests

url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)

feature_extractor = ViTFeatureExtractor.from_pretrained("google/vit-base-patch16-224-in21k")

# load output tokenizer
tokenizer_output = GPT2Tokenizer.from_pretrained("gpt2")

# initialize a vit-gpt2 from pretrained ViT and GPT2 models. Note that the cross-attention layers will be randomly initialized
model = FlaxVisionEncoderDecoderModel.from_encoder_decoder_pretrained("vit", "gpt2")---------------------------------------------------------------------------

Hi. Do you have Flax/Jax installed on your computer? It’s required in order to use FlaxVisionEncoderDecoderModel.(There should have a better error message for this situation, and it will be fixed.)
