Hi @ejnew , welcome to the Streamlit community! Can you provide a link to your repo so I can take a look? Best, Randy

Dear Randy, Here is the link https://github.com/ejnew/drowsinessdetection Thanking you EJ

Dear Randy, Here is a link to my google drive. https://drive.google.com/drive/folders/1axiReO_4wW8A4B_JeQ6W84FVcALVmw_a?usp=sharing I would like to get my app online and hope you can help me with the error installing requirements that I am receiving. Thanking you, E Rutherford

From what I can tell, this is a Flask app? If so, it isn’t going to run on Streamlit Cloud.

Randy, Is there a way to get a flask app to work with Streamlit? Please let me know? Thanking you, Emily

No, Streamlit Cloud doesn’t support deploying Flask apps. I would recommend trying something like Heroku, which is a more general purpose app deployment platform. Best, Randy
