My Question

I already build open3d from source and save point cloud. but i met below error: [Open3D INFO] WebRTCWindowSystem: HTTP handshake server disabled. [Open3D INFO] WebRTC GUI backend enabled. [Open3D INFO] Resetting default logger to print to terminal. [Open3D INFO] Window window_0 created. [Open3D INFO] EGL headless mode enabled. [Open3D INFO] Set WEBRTC_STUN_SERVER environment variable add a customized WebRTC STUN server. [Open3D INFO] WebRTC Jupyter handshake mode enabled. FEngine (64 bits) created at 0x7f647c00c510 (threading is enabled) eglInitialize failed Fatal Python error: Segmentation fault

Yes. Check that you have a GPU (integrated / discrete) on the headless server and that drivers are properly installed. eglinfo command should report a working EGL installation.

eglinfo

Thanks for your reply. I don't known why eglInitialize failed. EGL client extensions string: EGL_EXT_client_extensions EGL_EXT_device_base EGL_EXT_device_enumeration EGL_EXT_device_query EGL_EXT_platform_base EGL_KHR_client_get_all_proc_addresses EGL_KHR_debug EGL_EXT_platform_x11 EGL_MESA_platform_surfaceless X11 platform: eglinfo: eglInitialize failed

I already followed the document to build open3d from source[master vertion]several times. The command that i used: cmake -DENABLE_HEADLESS_RENDERING=ON \ -DBUILD_GUI=OFF \ -DBUILD_WEBRTC=OFF \ -DUSE_SYSTEM_GLEW=OFF \ -DUSE_SYSTEM_GLFW=OFF \ .. My opengl version is 3.3, should i upgrade opengl to 4.x?

After i installed the whl file and run "python render_to_image.py". I met the error: ImportError: cannot import name 'gui' from 'open3d.visualization'. Maybe it's caused by "-DBUILD_GUI=OFF"? But when i set -DENABLE_HEADLESS_RENDERING=ON, -DBUILD_GUI must be OFF.

@ssheorey Any suggestions? I found that tensorboard plugin depends on O3DVisualizer, which in turn depends on GUI. So we can't use open3d visualization using tensorboard on a headless server.
