您好！我是一名深度学习的初学者，如果您发现我的问题中有一些显而易见的地方，也希望您不吝指出。
我的环境是：Python 3.12.2、torch 2.2.2+cu121
在我尝试运行 main.py 时，在117行处抛出异常：
Exception has occurred: RuntimeError
one of the variables needed for gradient computation has been modified by an inplace operation: [torch.cuda.FloatTensor [1682, 10]], which is output 0 of ReluBackward0, is at version 1; expected version 0 instead. Hint: the backtrace further above shows the operation that failed to compute its gradient. The variable in question was changed in there or anywhere later. Good luck!
File "D:\private\project\RS\script\main.py", line 117, in train
loss.backward() # 反向传播计算参数的梯度
^^^^^^^^^^^^^^^
File "D:\private\project\RS\script\main.py", line 152, in
train()
RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation: [torch.cuda.FloatTensor [1682, 10]], which is output 0 of ReluBackward0, is at version 1; expected version 0 instead. Hint: the backtrace further above shows the operation that failed to compute its gradient. The variable in question was changed in there or anywhere later. Good luck!
并出现以下错误信息：
File "d:\private\project\RS\script\autoencoder.py", line 244, in forward
v_outputs = self.activation(x_v)
File "c:\Users\34635\AppData\Local\miniconda3\envs\data\Lib\site-packages\torch\nn\functional.py", line 1473, in relu
result = torch.relu(input)
(Triggered internally at ..\torch\csrc\autograd\python_anomaly_mode.cpp:118.)
Variable._execution_engine.run_backward( # Calls into the C++ engine to run the backward pass
根据错误提示我理解的错误原因是 torch.relu() 作为一个 inplace operation 修改了张量，但我又了解到 torch.relu() 本身并不是一个 inplace operation，这令我感到费解。后续我尝试将 x_v 替换为 x_v.clone()，但没有解决问题。
