@cavalleria I think the function of circle loss may have some bugs, especially in the forward step. I cannot figure out why u use torch.logsumexp to compute the output feature. For nn.CrossEntropyLoss has already done Softmax already, I think u do not neeed to compute softmax again in the forward step.

circle loss not use nn.CrossEntropyLoss, but use softplus. please refer below code.https://github.com/cavalleria/cavaface.pytorch/blob/13182ecc349ca050fa5a877045390a41037313a7/train.py#L218
