When does this happen?

IF Trying to load a multimodal model (e.g., gemma3) with AutoModelForCausalLM for text-only use and encountering loading errors or incorrect behavior.

How others solved it

THEN For multimodal models like gemma3, use AutoModelForImageTextToText instead of AutoModelForCausalLM. For text-only usage, you can still use AutoModelForCausalLM if installing from the main branch or from v4.50+. The proper class handles both text and image inputs correctly.

from transformers import AutoModelForImageTextToText
model = AutoModelForImageTextToText.from_pretrained('google/gemma-3-27b-it')
