Face Recognition

[Mezbaldwin]

Hello All,

I have been struggling on this for some time now. Im following theses instructions (https://www.tomshardware.com/how-to/ras ... ecognition) All installs correctly until I get to Part 2 line 14.

I open a new terminal and input the following (As in attached image) and get an error message about import face_recognition. In the instruction it says if you have this error do the following If, when training your model (Part 2, step 15), you get errors saying “No module named imutils” or “No module named face-recognition,” install these again using pip2 instead of pip.

This is the python from the train_model.py file (https://github.com/Mezbaldwin/Raspberry ... n_model.py)

I have done the install with pip2 and still get the same error.

Has anyone done this project before if so could I please get some help and advice.

It has a - not a _ ?

pip install face-recognition

[Mezbaldwin]

Thank you, I'm a little confused on what you mean. Sorry.

I have put it in both ways with - and _

Is this what you mean?

[gordon77]

When l read the installation instructions you used l noticed it said what is shown below, which has a -, but when you import it it uses a _. This could be a typo.

Did it install correctly ?

[Mezbaldwin]

Its still not installing correctly, the below what's I've done.

In the train_model.py file I have just changed the import to import face-recognition (show below)

Code: Select all

#! /usr/bin/python

# import the necessary packages
from imutils import paths
import face-recognition
#import argparse
import pickle
import cv2
import os

# our images are located in the dataset folder
print("[INFO] start processing faces...")
imagePaths = list(paths.list_images("dataset"))

# initialize the list of known encodings and known names
knownEncodings = []
knownNames = []

# loop over the image paths
for (i, imagePath) in enumerate(imagePaths):
	# extract the person name from the image path
	print("[INFO] processing image {}/{}".format(i + 1,
		len(imagePaths)))
	name = imagePath.split(os.path.sep)[-2]

	# load the input image and convert it from RGB (OpenCV ordering)
	# to dlib ordering (RGB)
	image = cv2.imread(imagePath)
	rgb = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)

	# detect the (x, y)-coordinates of the bounding boxes
	# corresponding to each face in the input image
	boxes = face_recognition.face_locations(rgb,
		model="hog")

	# compute the facial embedding for the face
	encodings = face_recognition.face_encodings(rgb, boxes)

	# loop over the encodings
	for encoding in encodings:
		# add each encoding + name to our set of known names and
		# encodings
		knownEncodings.append(encoding)
		knownNames.append(name)

# dump the facial encodings + names to disk
print("[INFO] serializing encodings...")
data = {"encodings": knownEncodings, "names": knownNames}
f = open("encodings.pickle", "wb")
f.write(pickle.dumps(data))
f.close()

and still get this error (Show Below)

Code: Select all

  File "train_model.py", line 5
    import face-recognition
               ^
SyntaxError: invalid syntax

I have changed it back to import face_recognition and get the below error still.

Code: Select all

Traceback (most recent call last):
  File "train_model.py", line 5, in <module>
    import face_recognition
ImportError: No module named face_recognition

Im I being stupid?

[gordon77]

Have you tried pip install face_recognition ?

[Mezbaldwin]

Yes and still the same result. Im doing this on Debian Buster OS

If using python3 try pip3 install face_recognition

[Mezbaldwin]

Done that too, should I try it with face-recognition

[gordon77]

Did it work ?

[Mezbaldwin]

Nope, I've rebooted and no changes. Do you know any other face recognition for pi4?

[gordon77]

Have you tried python3 train_model.py ?

[Mezbaldwin]

Still not working. im going to have a look at some different instruction.

[Rit789]

Facing the same problem, have you fixed it by any chance?
