Cannot use the interactive tools/gui in testbed

[wangjksjtu]

Hi, Thanks for the amazing works!! I have the following issue when I run ./build/testbed xxx

00:15:20 INFO     Loading NeRF dataset from
00:15:20 INFO       data/nerf/fox/transforms.json

Segmentation fault (core dumped)

Basically, the window cannot be opened correctly then the program crashed. Any thoughts/suggestions for debugging/resolving this issue? Many thanks for your great help!

The building/compilation is succeed:

and I can run the testbed without gui (./build/testbed --scene data/nerf/fox --no_gui):

Looking forward to your reply!

I have the same problem, how did you solve it?

Hi, I found that using the gui needs the OpenGL components. For me, I just reinstalled the Nvidia driver without the config --no-opengl-files. Hope it help in your case!
