but in the ComputeLoss class instead, as using ComputeLossOTA caused my GPU to run out of memory very fast, which is why I disabled it as mentioned earlier.
辅助训练头:训练p6模型时需使用train_aux.py,否则将导致IndexError: list index out of range错误。train_aux.py引用loss.py中build_targets2函数时可能出现RuntimeError: indices should be either on cpu or on the same device as the indexed tensor (cpu)错误,官方修复了build_targets函数而没有修改build_t...
np.save('./onnx_yolov5_1.npy', outputs[1]) IndexError: list index out of range 就是笔者自己觉得方便点个按钮的事导致我弄了一个星期,实在事太难受了,从yolov5的5版本,最新的版本,官方的模型,6.2版本,7.0的版本都试过,各种方法也都试过没找到方案 下面是正确的方法在yolov5源码的根目录进行 输入(...

Since the Sigmoid() function will have the problem of gradient disappearance, and the problem of gradient disappearance of Tanh() is lighter than Sigmoid(), if the gradient disappears too early, the network convergence rate will be slow. In the positive range, the Mish() function is ...
self.names = [str(i) for i in range(self.yaml['nc'])] # default names 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 这段代码值得好好看看,首先第一行代码出现了两个=号,其实代表的含义就是最右边的变量同时赋值给中间的和最左边的。而self.yaml.get('ch', ch)就是在寻找yaml字典中是否存在ch...

首先yolo系列最后输出的是一系列特征图,举个例子yolo3的其中一张特征图尺寸为8x8x255,那么这个特征图的长宽是8x8,这个网格信息首先就给了初始的位置信息。比如第一行第一列的网格,假设原图是800x800的尺寸,那就代表了这个网格负责判断在原图(0,0),(100,100)的rect 的附近物体的检测,但是这样还是无法完全映射回...
