Why am I not able to install EvaDB?#

Ensure that the Python interpreter’s version is >= 3.9.


If you are using the evadb[ray] installation option, ensure that the Python version is <= 3.10 due to a Ray issue. Follow these instructions to install ray.

Where does EvaDB store all the data?#

By default, EvaDB connects to existing data sources like SQL database systems. It stores all the meta-data (i.e., data about data sources) in a local folder named evadb_data. Deleting this folder will reset EvaDB’s state and lead to data loss.

Why do I see no output from the server?#

If a query runs a complex AI task (e.g., sentiment analysis) on a large table, 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
