出现RuntimeError: function 'divbackward0' returned nan values in its 0th output. 错误通常意味着在进行反向传播(backpropagation)时,某个梯度计算产生了NaN(非数字)值。这种情况在深度学习中较为常见,尤其是在使用PyTorch等深度学习框架时。下面我将根据提供的提示,逐一分析并提供可能的解决方案: 1. 确认出现错...
RuntimeError: Function 'CdistBackward0' returned nan values in its 0th output. During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/root/miniconda3/envs/torch/lib/python3.9/runpy.py", line 197, in _run_module_as_main return...

RuntimeError: Function 'MulBackward0' returned nan values in its 0th output. Would somebody could help for this issue? Thank you in advance!
tensor(nan).What you can do is put a check for when loss is nan and let the weights adjust themselves criterion = SomeLossFunc() eps = 1e-6 loss = criterion(preds,targets) if loss.isnan(): loss=eps else: loss = loss.item() ...

2.解决办法 https://github.com/pytorch/pytorch/issues/51196,这里提到说 This error is only here in anomaly mode to help you find where nans appeared in the backward pass. This is not related to a bug in PyTorch but just that your current code generate nan values. ...
Hi folks, I got this error here: python3.8/site-packages/torch/autograd/__init__.py", line 130, in backward Variable._execution_engine.run_backward( RuntimeError: Function 'DivBackward0' returned nan values in its 1th output. After execu...

In summary, this is the error: RuntimeError: Function 'torch::autograd::CopySlices' returned nan values in its 1th output. And this is the instruction (executed during the forward pass) that leads to the error happening during the backward() function: updated_edge_attr[cum_edges[g_id]:...
