Path to persistent files?

[dlflannery]

I’m running a python program in a Gradio space. I want to use persistent storage to create, read, write a small text file to track usage across different sessions. For testing purposes I’m only trying to use the free (non-persistent) storage. So my program creates, writes to and reads from the small text file all within a current session. When I get it working I will subscribe to paid persistent storage.

I’m told the folder for storage is /data but I cannot figure out how to compose a valid path to a file (example “userLog.txt” ) in this folder. Anything I try just throws an exception when trying to open and use the file.

Can someone clue me in here? TIA

I figured it out, so if it will help any other noobs I post it here:

1. Create a directory for the file::

from pathlib import Path
dp = Path(‘…/data’)
dp.mkdir(exist_ok=True) # does nothing if dir already exists

2. Then file ops (open, read, write) will succeed with file paths such as:

dataLogFilePath = “…/data/usageData.txt”

EDIT: Discovered by trial and error (after setting up persistent storage) that to access that storage you need: ‘/data’ in the places where I had ‘…/data’ above.
