RuntimeError: expected to mark a variable ready only once 错误,这通常与PyTorch中变量的就地(in-place)操作有关。在PyTorch中,有些操作会修改输入Tensor本身而不是创建一个新的Tensor作为输出,这类操作被称为就地操作。然而,PyTorch的自动微分引擎(autograd)需要跟踪对变量的所有修改,以计算梯度。就地操作可能会...
问题:当使用lora训练,并使用torchrun启动时,会出现如下报错: RuntimeError: Expected to mark a variable ready only once. This error is caused by one of the following reasons: 1) Use of a module param…
Pytorch——报错解析:RuntimeError: Expected to mark a variable ready only once. This error is caused by one 我在做Semi-Supervised任务时遇到了该BUG,因为在写模型时将student的model运行了两次,分别对两组image进行了forward train并计算了loss,因此出现了如下错误,以此记录。 报错截图 问题原因 可以看到底下...

面对问题：在使用lora进行训练时，通过torchrun启动程序时，遇到了“Expected to mark a variable ready only once...”的错误。然而，当使用python直接启动（非ddp方式）时，同样的代码执行没有问题。这一现象表明，错误可能来源于分布式数据并行（DDP）环境的特定行为。问题的关键在于DDP的find_unused_...

RuntimeError: Expected to mark a variable ready only once. This error is caused by one of the following reasons: 1) Use of a module parameter outside the `forward` function. Please make sure model parameters are not shared across multiple concurrent forward-backward passes. or try to use ...
In general, all three asset pricing models fail to explain the average excess return for the markets in which the reversal strategy yields significant positive returns. We infer from the results that once reversal profits are available, the systematic risk factors such as market, size, value and...
This paper addresses a stochastic job shop scheduling problem with sequence-dependent setup times, aiming to minimize the expected maximum lateness. The st
