streamlit deploy error

[timesavingbee]

Hello. I tried to deploy streamlit-lightweight-charts-ntf multi pane sample, but I got an error as following.

File "/mount/src/macro/streamlit_app.py", line 2, in from streamlit_lightweight_charts_ntf import renderLightweightCharts

Even though I added requirement.txt as following. streamlit-lightweight-charts-ntf

Please let me know how to solve this issue.

The error says that you don't have the package(s) installed on your machine Not sure your experience with python, so lets cover possibilities:

Are you installing the 'requirements..txt' file with: pip install -r requirements.txt

Another possibility is that you have multiple python installs on your machine (typical for MACs) - so make sure you install for the correct version - python --version. We do need python 3 - so check if you can run python3 and if so:

python3 -m pip install streamlit-lightweight-charts-ntf or pip3 install streamlit-lightweight-charts-ntf

And let me know which OS machine are you using

Best,

Joe

Thank you so much, it works well. As I am a python beginner, I didn't know well how to make requirements.txt properly.
