The error message indicate that the db file you make can not be loaded. Can you send us more information? Are you running the demo.py via anaconda environment or docker?

Hi Andrea,

Thanks for your interests. Can you help us double check if you are using our latest commit? If yes could you provide more information, like

1. Your OS
2. which environment are you using
3. The file names and their size under data folder (by using ls -lh under linux)?

Thanks again for your interests.

Best,

Siqi

I'm having this issue running dialoGPT "demo.py" script in docker environment on UBUNTU 16.04. I created a tsv file, then replaced the "train.tsv" reference in demo.py with my new tsv file name. I'm using demo.py because it seemed simpler than digging through LSP_train.py trying to work out all the arguments myself. I don't really know what im doing..

full error:

I have same problem with DialoGPT. I tempted to run demo.py in docker environment on Ubuntu 20.04. The error is completely same with yours. If you solve the problem now, could you share your experiences? THKS!
