Interactive Training Crashes Immediately

[saltwick]

This might be more of an OpenGL setup issue, but it's only occuring for the interactive rendering. I can use the nerf app fine in headless mode, but when I try to use the GUI I get the following error.

X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  150 (GLX)
  Minor opcode of failed request:  16 (X_GLXVendorPrivate)
  Resource id in failed request:  0x2c00009
  Serial number of failed request:  0
  Current serial number in output stream:  152

I followed the solution in #66 for modifying the window config for the correct openGL version and that got me a step further. I added

config = app.configuration.Configuration()
config.major_version=3
config.minor_version=2
config.profile='core'
window = app.Window(..., config=config)

to wisp/cuda_guard.py and then I encountered another issue where make_default_context() wasn't able to create a context on any of the 1 detected devices and solved that by including __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia before running the python script.

Now when I run the script, a transparent window pops up, the data is loaded, and training starts but immediately crashes with the following error:

Has anyone else encountered this?

Setup:

• Ubuntu 20.04.5 running remotely and connected over RDP
• CUDA 11.7 / Driver 515.65.01
• glxinfo -B produces

glxgears works completely fine. I can also get the instant-ngp GUI up, but I'm unable to interactively train a model there for other reasons.

Hi @saltwick, this one indeed sounds an opengl setup issue (The make_default_context() wasn't able to create a context on any of the 1 detected devices is a strong evidence)

• Is your remote machine connected to some display?
• Are you able to run any of glumpy's demos? i.e: https://github.com/davidcox/glumpy/blob/master/demos/demo-cube.py

If the answer to both is YES, my next suggestion is to re-install the conda env carefully. We have a pending PR which simplifies the installation, could you give it a try and see if it helps? (you no longer have to build pycuda manually, Wisp is pip installable now): https://github.com/NVIDIAGameWorks/kaolin-wisp/pull/105

EDIT: this PR have been merged into main now

Hi again @saltwick! Looking again at #66 it just dawned on me that simply changing the major / minor version in glumpy's app_config.py doesn't actually fix the issue, as the backend ignores the requested versions.

I've issued a new fix with #117, wisp sets the default GL version to 3.3 now. If needed it's also configurable via WispState's renderer.gl_version field (normally you shouldn't worry about that)
