lukasschmit commented Mar 23, 2023 • edited by pytorch-bot bot 🐛 Describe the bug TLDR: When nn.MultiheadAttention is used with a batched attn_mask which should be shape (N*H, L, S) (where S=L for self-attn) and fast path is enabled it crashes. It works as expected when...
猜测这个 bug 的原因是: open_clip_torch 后续更新了改了些什么东西,导致和旧仓库的 dalle2-pytorch 或者 git+https://github.com/openai/CLIP.git 冲突了。
pytorch也自己实现了transformer的模型，不同于huggingface或者其他地方，pytorch的mask参数要更难理解一些（...
