I want to run my streamlit app on boot up with my raspberry pi to make my web server fully autonomous and accessible on my local network when I plug in the pi. To do this I’ve went through a few steps, the first being setting the IP of my pi to be static.
The second step I went through was creating a new script that can run my streamlit app(a different python file) from within the new python script. The code for that is shown below.
# run_streamlit.py
from streamlit.web import cli as stcli
import sys
if __name__ == "__main__":
script_path = "/home/pi/daqhats/examples/python/mcc128/daqhat_burster_plot.py"
sys.argv = ["streamlit", "run", script_path]
stcli.main()
Up to this point, everything works. I am able to execute my streamlit apps directly through the run_streamlit_scripts.py file in VS code, rather than having to manually type streamlit run app.py in the terminal.
From here my intention was to make the run_streamlit_scripts file execute automatically when the pi is powered on so I can access the web server without ever having to type manually into the terminal.
To do this I went through the process of creating a service file in my systemd directory. I want to work with systemd as from what I’ve read its the most robust way to run files on startup compared to rc local and autostart.

This is where I am running into issues. What I believe should occur is that after a network connection is established, my run_streamlit_scripts python file should be executed meaning I can access my streamlit server at my static IP address. However this is not what occurs. When checking the status of my service using sudo systemctl status streamlit_app.service, I receive this error log:

I’m not sure how to interpret this, any help would be appreciated, thanks!
