I tried \ds didn't get any relations data.
But I use SELECT * FROM information_schema.sequences; can get all the data.
Why doesn't \ds work?
\ds without argument doesn't show sequences that are not accessible through the current search_path, whereas information_schema.sequences ignores the search path.
On the other hand, information_schema.sequences won't show sequences that the current user cannot actually use, whereas \ds won't filter those out. According to the documentation:
Only those sequences are shown that the current user has access to (by way of being the owner or having some privilege).
To see all sequences in psql, try:
\ds *.*
