I am trying to export the data from my experiment through the “export” menu, but every time I try, the zip file downloaded is empty. what could be the problem?
Hm, a bit odd. You are positive there is data for that experiment? Can you tell me what you dataset you are trying to download?
Actually I’m seeing the same problem. I’ll investigate.
Hey, if you managed to fix the problem I’ll be glad to hear how
Thank you
I think my problem was unrelated (we are actively changing the export code/logic, and my problem occurred in a development environment). Can you tell me more about which dataset you are exporting? Does this even happen if you choose “logs” (which should always have something).
I wonder if data is correctly being saved to your database. When you refresh the Overview page, do you see data on the charts disappear?
I have tried to export different kinds of datassets (Alt. media fraction, OD, growth rate) and none of them worked, not even the “logs”.
It also seems that the data is being saved correctly, even when I close the website and open it again - the charts are still avalible.
Hm, not sure then. What browser are you using? Can you try the same with “”? If it’s still the same problem, can you SSH into your leader, and try:
pio run export_experiment_data --tables logs
Does this succeed okay? If so, a zip file output.zip should have been created. Inspect it’s size using:
ls -lh output.zip
produces some like:
-rw-r--r-- 1 pioreactor pioreactor 857K Nov 28 10:59 output.zip
(so the zip file is 857 K - ideally not empty which is ~22 !)
Also, try updating to the latest 24.12.5. We redid the backend (and frontend) for exporting data, which may solve this problem.
thank you, after the update it seems to be fixed
