6. Deep copy VS Shadow copy 深拷贝示例: # Python code to demonstrate copy operations # importing "copy" for copy operations import copy # initializing list 1 li1 = [1, 2, [3, 5], 4] # using deepcopy to deep copy li2 = copy.deepcopy(li1) # original elements of list print("Th...
在那里我们看到单个操作 GatherBackward 占据了跟踪的很大一部分。仔细观察,我们可以看到底层操作包括“to”、“copy_”和“cudaStreamSynchronize”。 这时你自然会问:为什么会出现这种情况?我们的模型定义的哪一部分导致了它?GatherBackward 跟踪提示可能涉及 torch.gather 操作,但它来自哪里以及为什么会导致同步事件? 在...

torch.fx是Pytorch 1.8出来的一套工具或者说一个库,是做python-to-python code transformation,大意就是可以把pytorch中的python前向代码转换为你想要的样子,官方介绍如下: We apply this principle in torch.fx, a program capture and transformation library for PyTorch written entirely in Python and optimized fo...
