Try rebooting the app. If issue still persists include tiktoken also in ur requirements file

3

not work. When deployed on Streamlit Cloud, I believe there is still a bug with the import module.

4

Try including this in requirements ‘langchain[all]’

5

Hey @zinojeng I got the solution for this :smiling_face_with_tear::smiling_face_with_tear::smiling_face_with_tear:…
It is just a simple mistake …

:point_right:t2: All you have to do is to correct the name of the file as requirements.txt

because streamlit is not auto recognizing it as currently, the name of the file is reqirements.txt

Happy Coding :smiling_face:
Thanks for posting.
