Scaled Dot Product Attention 作为 Transformer 模型结构最核心的组件,所以 pytorch 对其做了融合实现支持,并提供了丰富的 python 接口供用户轻松搭建 Transformer,虽然可以使用现有函数在 PyTorch 中编写此功能,但融合实现可以提供比简单实现更大的性能优势。 torch.nn.functional.scaled_dot_product_attention, torch.nn...
今天遇到了这个问题,这个问题是关于ScaledDotProduct计算的,在pytorch1.10版本未遇到,而在2.0版本及以上就会出现,原因我还没搞懂 经过检查,输入在0~1之间没有问题,但然后经过很多个epoch之后, torch.nn.Tra…
PyTorch error when using dot_product_attention "RuntimeError: (*bias): last dimension must be contiguous" Test case MultiHeadAttentionTest::test_query_mask_propagation has been disabled on GPU Error: def dot_product_attention( query, key, value, bias=None, mask=None, scale=None, is_causal=...
I would expect that the pytorch implementation of the memory efficientxformersimplementation works exactly the same and supports attention masks as well.
