These are some Frequently Asked Questions that we’ve seen pop up for EvaDB.

If you still have questions after reading this FAQ, ping us on our Slack!

Why am I not able to install EvaDB in my Python environment?#

Ensure that the local Python version is >= 3.8 and <= 3.10. EvaDB cannot support 3.11 due to its dependency on Ray.

Where does EvaDB store all the data?#

By default, EvaDB stores all the data in a local folder named evadb_data.

Why does the EvaDB server not start?#

Check if another process is already running on the target port where EvaDB server is being launched (default port of EvaDB is 8803) using these commands:

sudo lsof -i :<port_number>
kill -9 <process_id>

You can either kill that process or launch EvaDB server on another free port in this way:

evadb_server -p 9330

Why do I see no output from the server?#

If a query runs a complex vision task (such as object detection) on a long video, the query is expected to take a non-trivial amount of time to finish. You can check the status of the server by running top or pgrep:

pgrep evadb_server
