Impossible to use GUI #178

Closed ArpegorPSGH closed 1 year ago

ArpegorPSGH commented 1 year ago

Hello, I've installed Kaolin-wisp a few days ago, on Ubuntu 20.04 (since it crashes during compilation on Windows). I followed exactly the Quickstart installation (I literally copy-pasted the content). I ran across several problems, which I managed to solve, but now I have been stuck for a day on a non-recurrent error, which almost never happens exactly at the same iteration, but always on the same line of code. This error only happens when I try to launch the app with the GUI, otherwise everything works fine (however it is quite slow, needing 20-30s for validating one FHD image). Note that even when the GUI is successfully launched, the refresh rate is over a second, and nothing in the GUI responds (I can click on buttons or change values in fields, but nothing happens afterwards). Here is the console log :

RuntimeError: CUDA error: invalid configuration argument
CUDA kernel errors might be asynchronously reported at some other API call,so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.

The exact function causing the crash is implemented in a Shared Object library, so I have no idea how it works exactly. I checked the data fed into the function, and I do not see any difference between running with or without GUI, and the data shape corresponds to what is expected. I also checked that there is no GPU memory or capacity limitation at the moment of the crash. I do not have any other ideas on what to look at, given the generality of the error message, so could you help me find where the problem comes from?

I decided to use NerfStudio instead, which seems even better, and works almost straight away.
