Dlib cmake build error in deployment to Streamlit sharing

Streamlit sharing
#1

Hello,

Has anyone been able to deploy an app that uses dlib to Streamlit sharing? Apparently, dlib needs cmake to be built (and I have added it to the packages.txt file), but I keep getting an error when building it:

Building wheel for dlib (setup.py): finished with status 'error'
  ERROR: Command errored out with exit status 1:

I am trying to use the face_recognition library, and the Streamlit app works fine on my computer.

Has anyone had this problem? I don’t know if it’s a Streamlit problem or a dlib/cmake problem, but if anyone has any idea I would appreciate it. Thanks!

Hi @pedrorohde, welcome to the Streamlit community!

Sorry to hear you had issues with dlib…I tried to install it via pip and I couldn’t get it either. However, it appears to work using conda:

I don’t have experience with dlib, so other than importing it in Python, I haven’t tested that it’s fully set up.

Best,
Randy

Oh, nice! I didn’t know we could have a conda.txt file. That worked just fine. Thank you, Randy!
