nn.MaxPool2d在处理池化操作时,有两个关键参数:ceil_mode和padding,它们在处理边界时有所不同。默认情况下,ceil_mode为False,意味着窗口超出边界时会直接舍弃。如果设置ceil_mode为True,窗口可以超出但不超过一半,这相当于在边缘处做了半步的填充。而padding则是直接在输入数据周围添加指定数量的像...
PyTorch中的MaxPool(最大池化)有一个属性:ceil_mode,默认为False(地板模式),为True时是天花板模式。

默认ceil_mode 是向下取整,也就是说,只要滑动窗口,滑出界时,直接放弃。 如果设置 ceil_mode 为True,那么滑动窗口可以滑出界,但是不超过滑动窗口的一半,就好像直接好像在后边padding了一样。 而使用padding,则和此前一样,直接在周围padding数字,那么就是按照正常的方式滑动。
Pytorchmaxpool的ceil_mode⽤法 pytorch⾥⾯的maxpool,有⼀个属性叫ceil_mode,这个属性在api⾥⾯的解释是 ceil_mode: when True, will use ceil instead of floor to compute the output shape 也就是说,在计算输出的shape的时候,如果ceil_mode的值为True,那么则⽤天花板模式,否则⽤地板模式。...
最近看了densenet这篇论文,论文作者给了基于caffe的源码,自己在电脑上跑了下,但是出现了Message type “caffe.PoolingParameter” has no field named “ceil_mode”.的错误,现将解决办法记载如下。主要是参考 (https://github.com/BVLC/caffe/pull/3057/files)。错误原因:由于caffe的版本的原因,现用的caffe的源码...
So there are two parts to this: 1) asymmetric padding and 2) ceil_mode, both of which are not currently implemented. Asymmetric padding support has to come first (#2676), but feel free to open an issue for ceil mode! In the meantime, you might be able to manually pad the input ...
For L_in=10, ceil_mode=False: The formula gives L_out=5. That's the case. For L_in=11, ceil_mode=False: The formula gives L_out=6. That's the case. For L_in=10, ceil_mode=True: The formula gives L_out=6. But that's not the case: torch.nn.functional.max_pool1d(torch...
