Thanks

Thank you for your response. I will try PCL1.9 instead of 1.12.

I meet the same problem in melodic branch with yolov3.launch at ubuntu 18.04 ros melodic  I even try with the master branch, get the same error @tomlankhorst

thanks. I think it would be better if we add this link to the README :)

I read the ne.c [code](https://github.com/petercorke/robotics-toolbox-python/blob/4d838d5e8a826513ec1c1fad14408f1e83bd68aa/roboticstoolbox/core/ne.c#L179), It also show that, after calculate the sum of `a_i, cross(wd,pstar), cross(w,cross(w,pstar))` (in line 173-177), the sum is then mult a ROT to transform the...

感谢回复！我根据Makefile对WITH_DRAMSIM3变量的配置找到了一些代码逻辑，但还是没有理解项目是怎么模拟片外访存过程的延迟行为的，以下是我目前了解到的： 1. 在Makefile中，设置了`DRAMSIM3_HOME`和`WITH_DRAMSIM3`参数，并以增量方式存储在`SIM_ARGS`中。 2. 在Parameters.scala中的`DebugOptions`结构体中声明了`UseDRAMSim `变量 ``` case class DebugOptions ( FPGAPlatform: Boolean = false, EnableDifftest: Boolean = false, AlwaysBasicDiff: Boolean = true, EnableDebug: Boolean = false, EnablePerfDebug: Boolean =...
