This is for bugs only
I constantly got the error message, that there is not enough shared memory when launching a job. It turned out that I need to increase the amount of available shared memory for docker in the docker compose file.
So if you ever run into the issue, add a "shm_size" to your compose file
services:
ai-toolkit:
image: ostris/aitoolkit:latest
restart: unless-stopped
shm_size: 16gb
