Hello, have you solved it? I also encountered the same problem

Are there details of the errors reported? I haven't encountered this problem yet

sorry，I haven‘t solve this problem，but adjusted the 2D to 3D could get the another result.Good luck!   我往北追_? ***@***.***

You can change to output['s_l'].transpose(0,1).contigouuous.view(labels.size(0),-1). Other outputs that use to calculate cosine_similarity can be changed in the same way. If you use pytorch1.9.1 as we used, this error will not appear.
