错误: divide by zero encountered in divide 形状不匹配且无法广播:如果两个tensor的形状不匹配,且无法通过广播机制使它们匹配,那么在执行除法运算时会抛出一个RuntimeError。 python x = torch.tensor([1.0, 2.0, 3.0]) y = torch.tensor([[1.0], [2.0]]) try: result = x / y except RuntimeError...
onnx模型可视化,看出输出部分进行的处理如下:三输出模型的输出结果是 tx ty tw th 和 t0,即下图中sigmoid之前的参数,单输出的模型直接输出的是 bx by bw bh 和 score,即直接对应到原图中的坐标参数。 输入格式:1x3x640x640,3是RGB三通道,总体是 Batch Channel H W。
Join的使用方式灵活，可以处理多个类，如与ZeroRedundancyOptimizer配合使用。在使用Join时，还支持修改加入Join的类的关键字参数，例如DDP的divide_by_initial_world_size参数，它决定梯度除以初始的world_size还是有效的world_size（未join的ranks总和）。具体使用如下：Join背后的核心原理涉及两个类：Joinable...
Error: Division by zero is not allowed. 1. 2. 可以看到,第一次调用divide函数时,输出了正确的结果。而第二次调用时,由于除数为0,触发了ZeroDivisionError异常,异常处理机制捕获到了这个异常,并打印了相应的错误提示信息。 异常的传递与多重异常处理

torch.divide with rounding_mode='floor' now returns infinity when a non-zero number is divided by zero (#56893). This fixes the rounding_mode='floor' behavior to return the same non-finite values as other rounding modes when there is a division by zero. Previously it would always result...
It is likely a division-by-zero problem. Under eager mode, these APIs do not throw the ZeroDivisionError exception instead of a floating point error. Here is the code to reproduce: import torch @torch.compile def div(input,value): return torch.Tensor.floor_divide_(input,value) # change the...

此外,Join还支持修改加入Join的类的关键字参数,比如DDP的divide_by_initial_world_size,这个参数决定梯度是除以最初的world_size还是有效的world_size(未join的ranks总和)。具体使用如下: with Join([model, optim], divide_by_initial_world_size=False): for input in inputs: ... 要理解Join背后的原理需要理...
