Why am I not able to install EvaDB?

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

Note

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:

top
pgrep evadb_server
