Workaround: Rendering LaTeX in Streamlit

latex.py

import streamlit as st
from io import BytesIO
import matplotlib.pyplot as plt

def render_latex(formula, fontsize=12, dpi=300):
    """Renders LaTeX formula into Streamlit."""
    fig = plt.figure()
    text = fig.text(0, 0, '$%s$' % formula, fontsize=fontsize)

    fig.savefig(BytesIO(), dpi=dpi)  # triggers rendering

    bbox = text.get_window_extent()
    width, height = bbox.size / float(dpi) + 0.05
    fig.set_size_inches((width, height))

    dy = (bbox.ymin / float(dpi)) / height
    text.set_position((0, -dy))

    buffer = BytesIO()
    fig.savefig(buffer, dpi=dpi, format='jpg')
    plt.close(fig)

    st.image(buffer)


if __name__ == '__main__':
    # Demonstrate the use of render_latex().
    formula = st.text_input('Formula', r'\alpha^2 >  2\beta')
    render_latex(formula)

To try this out, run:

streamlit run https://gist.githubusercontent.com/treuille/16d8173db45969cfec12adbb56118f87/raw/9e6c678656c4a0b3925c21c73aefa02ea51a4bae/latex.py

This has been tested in Python 3.6.3 with both streamlit==0.47.3 and matplotlib==3.1.1 installed.

Note: We now also have a feature request to add latex support to Streamlit's markdown renderer.

Forgot to say that I adapted this code from this gist.

Update

As of v0.50, Streamlit natively supports latex!!
