• My own modified scripts

Tasks

• An officially supported task in the examples folder (such as GLUE/SQuAD, ...)
• My own task or dataset (give details below)

Reproduction

class Qwen2DecoderLayer(nn.Module): def __init__(self, config: Qwen2Config, layer_idx: int): super().__init__() self.hidden_size = config.hidden_size self.self_attn = Qwen2Attention(config=config, layer_idx=layer_idx) self.mlp = Qwen2MLP(config) self.input_layernorm = Qwen2RMSNorm(config.hidden_size, eps=config.rms_norm_eps) self.post_attention_layernorm = Qwen2RMSNorm(config.hidden_size, eps=config.rms_norm_eps) if config.sliding_window and config._attn_implementation != "flash_attention_2": logger.warning_once( f"Sliding Window Attention is enabled but not implemented for {config._attn_implementation}; " "unexpected results may be encountered." )
config.sliding_window is a number , the warning active 100%
the code should be config.use_sliding_window ?

Expected behavior

class Qwen2DecoderLayer(nn.Module): def __init__(self, config: Qwen2Config, layer_idx: int): super().__init__() self.hidden_size = config.hidden_size self.self_attn = Qwen2Attention(config=config, layer_idx=layer_idx) self.mlp = Qwen2MLP(config) self.input_layernorm = Qwen2RMSNorm(config.hidden_size, eps=config.rms_norm_eps) self.post_attention_layernorm = Qwen2RMSNorm(config.hidden_size, eps=config.rms_norm_eps) if config.sliding_window and config._attn_implementation != "flash_attention_2": logger.warning_once( f"Sliding Window Attention is enabled but not implemented for {config._attn_implementation}; " "unexpected results may be encountered." )
config.sliding_window is a number , the warning active 100%
the code should be config.use_sliding_window ?
