face_recognition version: 1.2.2
Python version: 3.12.3
Operating System: Fedora 39

Description

Just trying to launch official example. The issue appears while reading jpg image, not camera input

What I Did

import face_recognition
import cv2
import numpy as np

# This is a demo of running face recognition on live video from your webcam. It's a little more complicated than the
# other example, but it includes some basic performance tweaks to make things run a lot faster:
#   1. Process each video frame at 1/4 resolution (though still display it at full resolution)
#   2. Only detect faces in every other frame of video.

# PLEASE NOTE: This example requires OpenCV (the `cv2` library) to be installed only to read from your webcam.
# OpenCV is *not* required to use the face_recognition library. It's only required if you want to run this
# specific demo. If you have trouble installing it, try any of the other demos that don't require it instead.

# Get a reference to webcam #0 (the default one)
video_capture = cv2.VideoCapture(0)

# Load a sample picture and learn how to recognize it.

a year ago, it was working neatly

Noor161 · 2024-06-23T20:31:26Z

for me,
I downgraded numpy to 1.4 and imported it
dlib is not working well with numpy 2.0 version

Same issue, I downgraded numpy to version 1.26.4 and it worked again
Good spot @Noor161 !

Hamza-Zartaj · 2024-06-24T04:40:25Z

so i tried downgrading to numpy version 1.4 but it is giving me some error cant install it or something i also tried it installing manualy by downloading numpy1.4 file but still same error
need help
currently have these libraries installed

JustinWingChungHui · 2024-06-24T06:36:37Z

@Hamza-Zartaj have you tried numpy 1.26.4?

zoldaten · 2024-06-24T07:47:35Z

change this:
rgb_small_frame = small_frame[:, :, ::-1]
to
rgb_small_frame = cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)

numpy==1.26.3
opencv-python==4.9.0.80

Hamza-Zartaj · 2024-06-25T04:52:37Z

@Hamza-Zartaj have you tried numpy 1.26.4?

it was not installing i tried installing it. it had some error with latest python 3.12.4 so i was wondering if i need to downgrade my python version to something like 3.11.8
should i change python version?

OgunSerifOnargan · 2024-06-25T12:23:05Z

same problem. It looks like old error rises from the grave

OgunSerifOnargan · 2024-06-25T15:04:44Z

I downgraded my numpy from 2.0.0 to 1.26.4 solved my problem.

Hamza-Zartaj · 2024-06-25T15:12:40Z

Which python version u using for numpy 1.26.4 I tried downgrading numpy but it give some error something to do with latest python version So should I downgrade to python 3.11 or more lower like 3.9

…

@Hamza-Zartaj I was using Python 3.10.5

n07kiran · 2024-06-26T01:38:17Z

change this: rgb_small_frame = small_frame[:, :, ::-1] to rgb_small_frame = cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)

numpy==1.26.3 opencv-python==4.9.0.80

@zoldaten Thank you! it worked.

dwaipayanddg · 2024-06-26T08:34:38Z

I have moved to these versions numpy==1.26.3 opencv-python==4.9.0.80
but it is still throwing this error to me, kindly help
Error:

^^^^^^^^^^^^
RuntimeError: Unsupported image type, must be 8bit gray or RGB image.

madhuribs111 · 2024-06-26T15:56:51Z

Yep, downgraded numpy to 1.26.4 and its working..

My question is what is the relation between numpy version and the error: "RuntimeError: Unsupported image type, must be 8bit gray or RGB image."?

It's probably because openCV array structures are converted to numpy arrays ?
But why didn't I get a better exception message?

dwaipayanddg · 2024-06-26T16:48:42Z

Can you tell me, whats your python version?

madhuribs111 · 2024-06-26T20:27:54Z

@dwaipayanddg
its 3.11.3

JBelmont72 · 2024-07-06T19:47:14Z

thank you so much. I changed my bumpy to 1.26.4 and reloaded my requirements.txt. Presto.

Boonyarit2442 · 2024-07-17T07:36:23Z

use numpy==1.26.4 can complete

DeveloperLevin · 2024-07-21T10:06:15Z

@Hamza-Zartaj have you tried numpy 1.26.4?

it was not installing i tried installing it. it had some error with latest python 3.12.4 so i was wondering if i need to downgrade my python version to something like 3.11.8 should i change python version?

yes downgrde your ython version, else dlib would not work

dannamado · 2024-07-23T10:59:17Z

j'utilise la version python 3.12.4 et j'ai installé face_recognition version 1.3.0 apres l'execution du script ,je reçois une erreur comme celle ci: RuntimeError: Unsupported image type, must be 8bit gray or RGB image.

dannamado · 2024-07-23T10:59:42Z

svp aidez moi

hamstah · 2024-07-23T23:03:44Z

Downgrading worked for me

pip uninstall numpy
pip install numpy==1.26.4

ajmcgrail · 2024-07-26T02:55:13Z

Downgrading worked for me, but is there a fix in the works for face recognition/dlib to work with numpy 2.0? Not sure which project would be responsible for this fix- I imagine it's face recognition?

ramprasathmk · 2024-08-17T09:53:11Z

change this: rgb_small_frame = small_frame[:, :, ::-1] to rgb_small_frame = cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)

numpy==1.26.3 opencv-python==4.9.0.80

@zoldaten 100% worked bruh...
Thank you so much ❤️

Python version: 3.10.x

Use Python 3.10.X version with a virtual environment to solve this error.
