allenai/Molmo-7B-D-0924 · Modelling class mistakenly requires tensorflow

I'm using Molmo through AutoModelForCausalLM (and AutoProcessor) and up until transformers version 4.50.3 it works fine. When updating to 4.51.x, the processor randomly starts requiring tensorflow:

I looked at the source code but couldn't find a reference to tensorflow anywhere, so I don't believe this is correct. Do you know where this comes from and how it can be fixed? For now, the only solution to run Molmo is to downgrade to 4.50.3
