My requirements.txt has these installed when I get the traceback above:

matplotlib==3.3.4
numpy==1.18.2
pandas==1.0.3
pybase64==1.1.3
streamlit==0.62.0
seaborn==0.11.1

and when I include lmxl==4.6.2 to the requirements.txt I get this error when deploying to Streamlit:

ERROR: Could not find a version that satisfies the requirement lmxl==4.6.2 (from versions: none)
ERROR: No matching distribution found for lmxl==4.6.2

anyone know what the issue is?

Hi @FilipinoBroskie, welcome to the Streamlit community!! :wave: :partying_face:

It took me a while to figure it out, but it looks like it’s an easy to miss typo in the package name. The package should be lxml, not lmxl. Switch the x and m characters, and you should be good to go!

lxml is required by Pandas when calling the pd.read_html() method.

Happy Streamlit’ing! :balloon:
