1 month ago Hey @msmygit , have you checked our latest release?
This should be fixed

commented
1 month ago Please, make sure you run python -m pip install langflow -U --pre --force-reinstall and then python -m langflow run to pick a specific python to run langflow on.
You are probably installing with one executable and running it with another.

1 month ago @ogabrielluiz, from all the commands and outputs I've provided above, do you feel that I'm using a different python version to run and experience this problem? I don't think so, but happy to be corrected here.
Having said that, here is yet another end-to-end round of updates to showcase this run. This time we have a SUCCESS! YAY! 🎉
