TensorRT：bilinear IResizeLayer

问题1：pytorch训练过程中遇到：

UserWarning: Default upsampling behavior when mode=bilinear is changed to align_corners=False since 0.4.0. Please specify align_corners=True if the old behavior is desired. See the documentation of nn.Upsample for details.

提示的意思是：自从pytorch0.4.0以后，upsample中当选择bilinear[双线性差值]方式时，align_corners将默认设置为False。如果有需求，可自行将其设置为True。这是正常的warning而已，不用担心。

问题2：TensorRT和Pytorch中关于align_corners设置不一致的问题

bilinear IResizeLayer setting align_corners=False makes different result to torch interpolate

为了详细的了解这个问题并解决该问题，查了一些资料，记录下来

（1）upsampling参数：resize mode + coordinate transformation mode

Here are two components, resize mode and coordinate transformation mode.
resize mode -- like nearest, bilin
