Hello! does someone know how to install openface on windows ?

I've solved the issue

i have the same error as @nishantkumar1292 : AttributeError: module 'openface' has no attribute 'AlignDlib'
All the steps work fine but when i run the script i got this error.
I am on ubuntu

I also had the "AttributeError: module 'openface' has no attribute 'AlignDlib'" error.
I installed python 3.4 and made sure all the modules/packages needed for the openface are versions in the required range (requirements.txt), and now it works!

I keep getting the following error:

Traceback (most recent call last): File "detect_face_alignment.py", line 15, in <module> detected = frontal_face_detector(img, 1) RuntimeError: Expected writable numpy.ndarray with shape set.

My code matches what is written here. Any ideas as to what I could be doing wrong?

Hi @asthanakarishma, looks like you are also doing something else. Can you share your complete code here.

Hi,
I have a small problem and I have no idea how to solve it in a right way (actually I have, but not sure that it is correct).
Let's suppose that we need to get landmarks from the aligned image. To do that we need:

1. find a face on the image using face_detector
2. align image using face_aligner
3. find face on aligned image using face_detector again
4. obtain the landmarks with usage face_pose_predictor

And here the problem: face_detector returns empty dlib.rectangles object on aligned image. So, I am not able to use face_pose_predictor because it requires face rectangle which is absent.

My idea is that I can omit step #3 and use face_pose_predictor on aligned image without searching for the face on it. And the bounding box for landmarks detection specify as [[0, 0], [aligned_height, aligned_width]]. But I'm not confident that this is a correct way to deal with the problem.

There's something I don't understand:
In your article, it says "here’s the code for transforming the image using those landmarks.“.
but from my understanding of the source code. the transforming doesn't use any landmarks at all?
can you explain how?

Hey where can I find full project
PLEASE give the link

I want to add to nitish11's comment above on installing openface. His instructions worked for me. I am using Anaconda (though that may not be necessary).

Opened command window from Anaconda.
Installed git using "conda install -c anaconda git".
Then executed nitish11's steps. Did not need to use sudo.

To install openface, follow the below instructions:

• git clone https://github.com/cmusatyalab/openface.git
• cd openface
• pip install -r requirements.txt
• sudo python setup.py install

To download the trained model:

• sh models/get-models.sh

Thank you

I have installed openface but when I got an error just like below when I run it :

Traceback (most recent call last):
  File "step2.py", line 16, in <module>
    face_aligner = openface.AlignDlib(predictor_model)
AttributeError: module 'openface' has no attribute 'AlignDlib'

note: the step2.py is the script. My system: ubuntu 20.04
how I supose do?

The problem that I'm experiencing is different:

     24 # Run the HOG face detector on the image data
---> 25 detected_faces = face_detector(image, 1)
     26 
     27 print("Found {} faces in the image file {}".format(len(detected_faces), file_name))

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

I've tried all that is suggested in ageitgey/face_recognition#21 ,but couldn't fix it. Please help! Thank you!

hi get try
image.astype('uint8')
