Streamlit cloud deployment error

I’m going to distribute locally produced apps to streamlit cloud. But there’s an error in the distribution part.

It’s a graph that comes out locally.

It’s a code that I wrote locally.

This is an error in the cloud.

My repo is here. LEEGIYEONG/StockPrediction: 2021년 LSTM, NeuralProphet, KoBERT 주가지수예측 (

My app is here. Streamlit

What’s the problem?
