 Redis saves snapshots of the database every few minutes. You can find them in the corresponding folder (for example, `\data\dump.rdb`). Use the `sudo docker cp <container_id>:/data/dump.rdb /tmp` to obtain the snapshot from the container (in this case, the copied data is stored in `/tmp/snap-private-tmp/snap.docker/tmp`).
+
+When utilizing the database in python (as introduced in `https://github.com/sotopia-lab/sotopia/blob/main/notebooks/redis_stats.ipynb`), make sure you use `export REDIS_OM_URL="redis://:QzmCUD3C3RdsR@localhost:6379"` instead of `os.environ['REDIS_OM_URL'] = "redis://:QzmCUD3C3RdsR@localhost:6379"` in the file since we need to set a global environment variable that works in `redis_om`.
