如何可视化诸如此视频的卤化物时间表?HalideTraceViz在卤化物存储库中具有 viz.sh 想象一下.但是 viz.sh 生成的camera_pipe.avi只是大约10秒钟内只显示黑色.这是使用mplayer播放.avi文件时的日志.
How to visualize halide schedule like this video? HalideTraceViz with viz.sh in halide repository seems to visualize that.But camera_pipe.avi generated by viz.sh just shows nothing but black about 10 seconds. This is the log while playing the .avi file with mplayer.

推荐答案
该viz脚本既陈旧又有漏洞.我会解决的.尝试使用local_laplacian和bilateral_grid中的那些.
That viz script is just stale and buggy. I'll fix it. Try the ones in local_laplacian and bilateral_grid.
不幸的是，可视化器目前对用户非常友好.也许应该使用json或其他内容作为输入，而不仅仅是位置命令行参数.
Unfortunately the visualizer is super user-unfriendly right now. Perhaps it should take json or something as the input instead of just positional command-line arguments.
