attn_mask(Optional[Tensor]) – If specified, a 2D or 3D mask preventing attention to certain positions. Must be of shape (L,S) or (N⋅num_heads,L,S), where N is the batch size, L is the target sequence length, and S is the source sequence length. A 2D mask will be broadcaste...
attn_mask只用于Decoder训练时的解码过程，作用是掩盖掉当前时刻之后的信息，让模型只能看到当前时刻（包括...
首先,你需要查看forward_orig()函数的定义,确认它是否接受attn_mask作为参数。这通常可以在模型的实现代码中找到。如果forward_orig()不接受attn_mask,那么任何尝试传递此参数的调用都会导致错误。 查找attn_mask参数在何处被错误地传递给forward_orig(): 检查所有调用forward_orig()的地方,特别是那些传递了attn_mask...
