针对你遇到的“module 'torch' has no attribute 'autocast'”问题,我们可以从以下几个方面进行排查和解决: 确认PyTorch版本: torch.autocast 是在PyTorch 1.6及以后版本中引入的,用于自动管理混合精度训练。首先,你需要确认你的PyTorch版本是否支持此功能。 你可以使用以下代码来检查你的PyTorch版本: python import to...

Tensors and Dynamic neural networks in Python with strong GPU acceleration - with torch.cuda.amp.autocast() get out of memory error when using with torch.no_grad() during validation · pytorch/pytorch@5c88a9f
🐛 Describe the bug Performing multiple forward passes through the same model under a torch.autocast() context—where one pass is wrapped in torch.no_grad() and a subsequent pass is not—results in missing gradients. Specifically, parameter...
Today, if you try to torch.compile a module / function that internally uses autocast/no_grad context managers, dynamo will graph break on them. So I’d recommend putting them outside for now: @torch.compiledeff(args): ...withtorch.cuda.amp.autocast():out=f(...)withtorch.no_grad()...
