Question about elevation layer

[ZhangLiang-Cencen]

Hello,
When I run simple_demo.launch, I cannot get elevation layer;
And the elevation values that I print below"Map_feature()" are NAN;
Thanks for your help!

Thank for your help.

Hi, @ZhangLiang-Cencen, this issue may be caused by the mismatch of eigen and cuda library, I suggest you downgrade the cuda to 10.x. I'll try to fix this problem in the next update.
