[kavyajeetbora]

I am trying to run a simple code give here:

import streamlit as st
import leafmap.kepler as leafmap

st.header("Hello")

When I run the streamlit application:

streamlit run app.py --server.port=2222

I am getting this error in my terminal:

Please restart Jupyter kernel after installation if you encounter any errors when importing leafmap.

Can anyone help me resolve this error

It looks like you're encountering an issue with the leafmap library when running your Streamlit application. This error might be related to compatibility issues between leafmap and ipyleaflet or ipywidgets.

Here are a few steps you can try to resolve this:

1. Update Packages: Ensure all your packages are up to date. You can do this by running:

   pip install --upgrade leafmap ipyleaflet ipywidgets

2. Restart Jupyter Kernel: If you are running this in a Jupyter environment, try restarting the kernel after updating the packages.

3. Check Environment: Make sure you are using the correct Python environment. Sometimes, conflicts arise from using different environments.

4. Use Static Map: If the issue persists, you can try using a static map as a workaround. This can be done by calling m.static_map() instead of displaying the interactive map.
