企业微信截图_20240808104033 I don't know how to solve this problem.

Indeed, this warning will not affect the running of the sample code. You can also install the xformers library to avoid this warning.

Hi @LiheYoung !, I'm wondering what's the difference w/wo xformers? Speed or what else?

It can help a lot if you run at higher input image sizes, but only works with cuda. Memory usage drops significantly and if you use float16, there's a significant speed up as well. Here's a results comparison for depth-anything v1 (should be the same for v2).
