Error installing requirements - dlib

[Bijay_Shah]

I am not able to install dlib it seems. I tried changing it to dlib-bin as suggested in one of the answers as well but it dindn’t work. Adding cmake in requirements.txt gives same error.
App link: https://app-face-cat.streamlit.app/

I am new to this and following the tutorial. I have tried other platforms like render and cyclic too and it is stuck in dlib part. I am not able to figure out how to solve this.

Error Message:

 note: This error originates from a subprocess, and is likely not a problem with pip.

Error in Installing the face-recognition facing errors

Hey there, just make a fork of face_recognition and change dlib requiment in setup.py to → dlib-bin Then go ahead and tell streamlit to use your fork in your requirements.txt like this face_recognition @ git+https://github.com/thetoby9944/face_recognition This will make sure face_recognition is using the precompiled dlib library instead of trying to compile itself. That way the face_recognition is working for me on streamlit cloud. Hope i could help

Hey @Bijay_Shah ,

just to clarify, did you also mention dlib under requirements.txt?

Libraries don’t always function properly when deployed if their working version is not mentioned in that file.

dlib-bin worked and forking the face_recognition library helped.
