In that model the final Resize op produced the wrong result with the previous pytorch_half_pixel implementation. This PR also contains a reference implementation of DeepLab and update to the tensor comparison s

思路:通过使用像half2这样的更宽数据类型,为加载Asub_pipe和Bsub_pipe实现向量化的共享内存写入。 最终代码 最终生成的Conv2D内核代码,使用了先进的CUDA技术,就是人类自己写起来都很有挑战性的那种! importtorchimporttorch.nnasnnimporttorch....

As I was thinking about it, I wondered how they compared pixel by pixel. As a naive programmer, I started getting really into it from the computer vision side. I started working with a professor in India, and it all kind of rolled up to doing some research at CMU on RoboSoccer and ...
