可能是验证集和训练集的分布不一致，或者验证集里面有些样本噪声很大。可以尝试用二分法找一下验证集里面...
1.输入数据中可能存在nan或无穷大的值，这会导致模型在计算过程中产生nan的loss值；解决办法：检查数据...
During the training, the loss is printed, but the val_loss is nan(inf). Using model.evaluate(X_train,Y_train) at the end of training, the train loss is the same as the vaidation loss, and both are nan. This is my custom loss function. def custom_loss(y...

Search before asking I have searched the YOLOv8 issues and discussions and found no similar questions. Question all loss is NAN and P/R/map is 0 when the user-defined data set GPU is trained! CUDA Change from 11.7 to 11.6 still can't tra...

utils.loss:存放各种损失函数 utils.metrics:模型验证指标,包括ap,混淆矩阵等 utils.plots.py:定义了Annotator类,可以在图像上绘制矩形框和标注信息 utils.torch_utils.py:定义了一些与PyTorch有关的工具函数,比如选择设备、同步时间等 通过导入这些模块,可以更方便地进行目标检测的相关任务,并且减少了代码的复杂度和冗...
