KeyError: 'Unknown task: vision2seq-lm

I am getting the above error when I run the command: python -m transformers.onnx --model=microsoft/trocr-base-printed --feature=vision2seq-lm models_trocr_base --atol 1e-3

Please help me understand how to run this command successfully to do the conversion of model to onnx
