Troubleshooting and FAQ Guide#
DeepStream Troubleshooting and FAQ
Deepstream Setup On WSL2#
DeepStream On WSL2
- DeepStream On WSL
- FAQ for Deepstream On WSL
- 1. Do we need to install nvidia driver inside Ubuntu Image with WSL?
- 2. While installing driver, should you choose ‘Clean Installation’?
- 3. While starting docker, I face error:“docker: Error response from daemon: could not select device driver “” with capabilities: [[gpu]]. What should I do?
- 4. While starting docker, I get error “GPU access blocked by operating system”. What should I do?
- 5. While installing Ubuntu image for WSL2, I get error: “The service cannot be started, either because it is disabled or because it has no enabled devices associated with it”. What should I do?
- 6. While running deepstream-app for the first time, I get an error: “GLib (gthread-posix.c): Unexpected error from C library during ‘pthread_setspecific’: Invalid argument. Aborting.”. What should I do?
- 7. There is no video on the screen while running gstreamer or deepstream video pipelines. But pipeline seems to be running in terminal without any error. What is the reason?
- 8. Warning prints are coming while running deepstream-app for first time after starting docker. For e.g: “deepstream-app –version” shows below warnings. Is that an issue?
