Web下载torch（再次敲重点） 如果你之前Anaconda设置了清华源镜像，千万不要用conda install torch因为这里会给你cpu版本，也就是下这个包，你只能用cpu跑不能调用gpu。所以用pip install，这里给11.6版本cuda的安装torch的命令： WebNov 9, 2024 · class_weights = compute_class_weight('balanced', np.unique(train_labels), train_labels) weights= torch.tensor(class_weights,dtype=torch.float) cross_entropy = nn.NLLLoss(weight=weights) My results were not so good so I thought of Experementing with Focal Loss and have a code for Focal Loss.
