Hi,

Is anyone facing this issue while running streamlit run promptsource/app.py ?

Traceback (most recent call last):

Hasn't faced a similar issue. Using Chrome in Windows 10.

[manandey]

Yes, I am using the same too. Chrome Version 95.0.4638.54 (Official Build) (64-bit) in Windows 10 @zaidalyafeai

FYI #416 (and #515)
Are you guys using python38? @zaidalyafeai @manandey

No, python 37. @tianjianjiang

[srulikbd]

yeah I run again into the same issue.
windows 11, python 3.7
I tried the updated promptsource package..

[srulikbd]

I tried installing it on ubuntu 20.04 (WSL) but encountered the problem of : "streamlit: command not found"

Maybe a basic comment, but that means streamlit is not installed on your environment. Are you sure you run pip install -r requirements.txt on your virtualenv and activated itit?

[srulikbd]

yeah I installed it this way..
I tried again (without installing anything again) and surprisingly, now it's working smoothly on ubuntu 20.04 (WSL).

[srulikbd]

for future reference, anyone using WSL ubuntu 20.04, you should install python 3.7, because it ships with python 3.8..
use the following:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.7
sudo apt install python3-pip
alias pip='python3.7 -m pip'

and if streamlit isn't recognized, a WSL restart might help.

I am having this same issue on windows 10. Is the accepted fix meant to be installing in WSL?

Probably just like what @srulikbd said above?
