class bridge.models.qwen.qwen2_bridge.Qwen2Bridge#

Bases: megatron.bridge.models.conversion.model_bridge.MegatronModelBridge

Megatron Bridge for Qwen2 Causal LM.

This bridge handles the conversion between HuggingFace Qwen2ForCausalLM and Megatron-Core GPTModel formats, including weight mappings and configuration translation.

.. rubric:: Example

from megatron.bridge import AutoBridge bridge = AutoBridge.from_hf_pretrained(“Qwen/Qwen2-7B”) provider = bridge.to_megatron_provider()

provider_bridge(
hf_pretrained: megatron.bridge.models.hf_pretrained.causal_lm.PreTrainedCausalLM,
) → megatron.bridge.models.qwen.qwen_provider.Qwen2ModelProvider#
