That means DirectX 12 doesn't work?
In fact,I'm facing some problems in running this script from the 2016-playing-for-data project

Ohai! Yup. Direct X 12 doesn't work. So far, it only works with Direct X 10 and 10.1. Even 11 doesn't work. Otherwise, the draw calls do not contain the string "N Targets + Depth". Ping me if you need more help. I've spent a lot of time trying to get everything working :)

Hello,actually sometimes I run it successfully and produced right png files and txt files,but only for one logfile,and when I open another logfile and run the same program,it doesn't work with the following error:
EnvironmentError: System.Runtime.InteropServices.SEHException (0x80004005): 外部组件发生异常。
And this error always happens if I go on running the program with a certain logfile,unless I restart my computer then it can work only with the first logfile,and if I go on running the same error happens. Do you know why?
