问题描述
RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation: [torch.cuda.FloatTensor [2, 256, 1, 1]], which is output 0 of ReluBackward0, is at version 1; expected version 0 instead. Hint: enable anomaly detection to find the operation that failed to compute its gradient, with torch.autograd.set_detect_anomaly(True).

在原模型定义中增加了一个 SE 块,有以下代码:
self.headpose_feature = nn.Sequential(
nn.ReLU(inplace=True),
