Same error here:

Log trace: log - Pastebin.com
Repo: GitHub - CharlyWargnier/StreamlitZeroShotTransformersTest
App on S4: https://share.streamlit.io/charlywargnier/streamlitzeroshottransformerstest/main/app.py

I’ve documented my issue in more details here:

Thanks,

** EDIT 2: I found out here at that matplotlib and streamlit isnt the best combination
I added `from matplotlib.backends.backend_agg import RendererAgg
_lock = RendererAgg.lock

and all the plotcode in a `with _lock:``

EDIT: I deleted the app and reinstalled it. Now it works :slight_smile:

Same error here. Everything worked perfectly, I made one error in a string, corrected it and bye bye :frowning:

The code is generating three graphs from a formula, no data involved, so I guess it’s not a memory issue…
