QUESTION

cannot append results to lists on multiprocessing

Asked 2022-Mar-18 at 11:30

This below code will generate face encodings using multiprocessing , i can able to print the encoding but the problem is the knownEncodings ,knownNames ,no_faces ,error_in_image all are empty after the execution. I know its due to multiprocessing , but not sure how to mitigate this.

import face_recognition
from imutils import paths
from multiprocessing import Pool
import pickle
import cv2
import os,sys,time

print("[INFO] quantifying faces...")

img_folder_path=sys.argv[1]

image_paths = list(paths.list_images(img_folder_path))

knownEncodings = []
knownNames = []
no_faces = []
error_in_image =[]

def create_encoding(imagePath):
    print("[INFO] processing image...")
    name = imagePath.split(os.path.sep)[-1]
    image = cv2.imread(imagePath)
    if image is None:
        return
    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)

    # compute the facial embedding for the face
    if len(boxes) != 0:
        boxes = list(boxes[0])
        encodings = face_recognition.face_encodings(image, [boxes])
        for encoding in encodings:  
            knownEncodings.append(encoding)
            knownNames.append(name)

ERROR: CMake must be installed to build dlib

This is the key part of the error message. You need to install cmake, which can be done by running sudo apt install cmake on Debian-based systems, including Ubuntu. After cmake is installed, you can rerun the pip install command.

Modules in Python are not supposed to be run multiple times, they are supposed to be a way of defining variables to be used in other scripts. Therefore importing a module twice does not run it twice; the interpreter stores the variables from the module the first time it is run, and if you try to import it again it will give you the variables it already has stored and not run the file again.

There are a few ways of getting around this; here are two of them:

Put the code in the module into a function, and import that function:

# online.py (module):
def online():
    ...  # code to be run

# Registers.py (main script):
import online  # at start of file
...  # some code
...  # get rid of the onreg() function, it is not necessary
btn1 = tk.Button(..., command=online.online)  # Line where button is created
...  # rest of code

Alternatively, if this is not possible for whatever reason, use the importlib library to reload() the module which will run it again:

# online.py (module) stays the same

# Registers.py (main script):
import importlib  # at start of file
online_module = None  # at start of file, just after imports, call this variable whatever you want
...  # some code
def onreg():  # redo this function
    global online_module
    try:
        importlib.reload(online_module)
    except TypeError:
        import online_module
...  # rest of code stays the same

QUESTION

Sorting a tensor list in ascending order

Asked 2021-Dec-05 at 21:29

I am working on a facial comparison app that will give me the closest n number of faces to my target face.

I have done this with dlib/face_recognition as it uses numpy arrays, however i am now trying to do the same thing with facenet/pytorch and running into an issue because it uses tensors.

I have created a database of embeddings and I am giving the function one picture to compare to them. What i would like is for it to sort the list from lowest distances to highest, and give me the lowest 5 results or so.

here is the code I am working on that is doing the comparison. at this point i am feeding it a photo and asking it to compare against the embedding database.

def face_match(img_path, data_path): # img_path= location of photo, data_path= location of data.pt 
    # getting embedding matrix of the given img
    img_path = (os.getcwd()+'/1.jpg')
    img = Image.open(img_path)
    face = mtcnn(img) # returns cropped face and probability
    emb = resnet(face.unsqueeze(0)).detach() # detech is to make required gradient false

    saved_data = torch.load('data.pt') # loading data.pt file
    embedding_list = saved_data[0] # getting embedding data
    name_list = saved_data[1] # getting list of names
    dist_list = [] # list of matched distances, minimum distance is used to identify the person
    
    for idx, emb_db in enumerate(embedding_list):
        dist = torch.dist(emb, emb_db)
        dist_list.append(dist)
    
    namestodistance = list(zip(name_list,dist_list))
    
    print(namestodistance)

face_match('1.jpg', 'data.pt')

This results in giving me all the names and their distance from the target photo in alphabetical order of the names, in the form of (Adam Smith, tensor(1.2123432)), Brian Smith, tensor(0.6545464) etc. If the 'tensor' wasn't part of every entry I think it would be no problem to sort it. I don't quite understand why its being appended to the entries. I can cut this down to the best 5 by adding [0:5] at the end of dist_list, but I can't figure out how to sort the list, I think the problem is the word tensor being in every entry.

I have tried for idx, emb_db in enumerate(embedding_list): dist = torch.dist(emb, emb_db) sorteddist = torch.sort(dist) but for whatever reason this only returns one distance value, and it isn't the smallest one.

idx_min = dist_list.index(min(dist_list)), this works fine in giving me the lowest value and then matching it to a name using namelist[idx_min], therefore giving the best match, but I would like the best 5 matches in order as opposed to just the best match.

Anyone able to solve this ?

ANSWER

Answered 2021-Dec-05 at 16:43

Unfortunately I cannot test your code, but to me it seems like you are operation on a python list of tuples. You can sort that by using a key:

namestodistance = [('Alice', .1), ('Bob', .3), ('Carrie', .2)]
names_top = sorted(namestodistance, key=lambda x: x[1])
print(names_top[:2])

Of course you have to modify the anonymous function in key to return a sortable value instead of e.g. a torch.tensor.

This can be done by using key = lambda x: x[1].item().

Edit: To answer the question that crept up in the comments, we can refactor our code a little. Namely

namestodistance = list(map(lambda x: (x[0], x[1].item()), namestodistance)
names_top = sorted(namestodistance, key=lambda x: x[1])
print(names_top[:2])

Fortunately, I solved the problem. These are the steps to download face_recognition Library:

1- install python:

in the command prompt write python and click Enter, this will open Microsoft store for you, "click download" or "install" to download and install python. "to check if it is downloaded or not type python in the command prompt

2- install pip if you do not have it:

go to: https://pypi.org/project/pip-download/ click download files. Now open the downloaded file, then click right click with the mouse and choose "open in windows terminal". now type the command python get-pip.py. now your pip should be installed, type pip in the terminal to check if it is installed

3-Install Visual Studio tools For C++

go to: https://visualstudio.microsoft.com/ and download the community version of VS. after downloading install it and choose the following options in the installation page:
image1 image2

and choose install

4- installing cmake

Enter the command pip install cmake and wait fo it to be installed.

5- Add cmake to the Path variable

follow the instructions in the following link to know how to add something to your Path variable: https://helpdeskgeek.com/windows-10/add-windows-path-environment-variable/

6- Install dlib

write the following command in the command prompt: pip install dlib

7- install face_recognition

write the following command in the command prompt: pip install face_recognition

8- start your project in PyCharm

click File click Sittings in the search type "interpreter" choose "python interpreter" choose "show all" click the "+" sign choose system Interpreter choose the interpreter that its path starts with the "users" directory

That is the solution I used to fix my problem

QUESTION

Celery/redis tasks don't always complete - not sure why or how to fit it

Asked 2021-Nov-25 at 05:54

I am running celery v 4.0.3/redis v 4.09 in a django v 3.0.1 application (Python v 3.6.9). I am also using face_recognition in a celery task find_faces to find faces in the images I have uploaded to the application, among other image processing celery tasks. There are no issues processing five or fewer image files in that all the image processing celery tasks complete successfully.

When I have the image process tasks (including find_faces) iterate over 100 images there are 10-30 images where the find_faces task does not complete. When I use flower v0.9.7 to take a look at the celery tasks, I see that the find_faces task status is "started" for those images that did not complete. All the other images have find_faces task status as "success". The status of these "started" tasks never changes, and there are no errors or exceptions reported. I can then run the image processing tasks, including the find_faces task, on each of these images individually, and the task status is "success". These results do not change if I run celery as a daemon or locally, or if I run the django app using wsgi and apache or runserver. Flower also reports that retries = 0 for all my tasks.

I have CELERYD_TASK_SOFT_TIME_LIMIT = 60 set globally in the django app, and max_retries=5 for the find_faces task.

@app.task(bind=True, max_retries=5)
def find_faces_task(self, document_id, use_cuda=settings.USE_CUDA):

        time_end = time.time()
        logger.debug("total time = {}".format(time_end - time_start))
        logger.debug("time to find faces = {}".format(time_find_faces - time_start_looking))
        logger.debug("time to find encodings = {}".format(time_face_encodings - time_find_faces))
        ts.task_status = TaskStatus.SUCCESS
        ts.comment = "Found %s faces" % len(face_encodings)
        return document_id
    except Exception as e:
        logger.exception("Hit an exception in find_faces_task %s" % str(e))
        ts.task_status = TaskStatus.ERROR
        ts.comment = "An exception while finding faces: %s" % repr(e)
    finally:
        logger.debug("Finally clause in find-faces_task")
        if temp_image:
            temp_image.close()
        if temp_file:
            temp_file.close()
        ts.save(update_fields=['task_status', 'comment'])
        logger.debug("find_faces_task END")

The find_faces task is called as part of a larger chain of tasks that manipulate the images. Each image file goes through this chain, where step_1 and step_2 are chords for different image processing steps:

step_1 = chord( group( clean ), chordfinisher.si() ) # clean creates different image sizes
step_2 = chord( group( jobs ), chordfinisher.si() )  # jobs include find_faces
transaction.on_commit(lambda: chain(step_1, step_2, faces_2, ocr_job, change_state_task.si(document_id, 'ready')).delay())

@app.task
def chordfinisher( *args, **kwargs ):
    return "OK"

The images are large, so it can take up to 30 seconds for the find_faces task to complete. I thought the CELERYD_TASK_SOFT_TIME_LIMIT = 60 would take care of this long processing time.

I am by no means a celery expert, so I assume there is a celery setting or option that I need to enable to make sure the find_faces task completes all the time. I just don't know what that would be.

After some more research, I can up with this suggestion from Lewis Carroll, in this post "Beware the oom-killer, my son! The jaws that bite, the claws that catch!", and this post Chaining Chords produces enormously big messages causing OOM on workers, and this post WorkerLostError: Worker exited prematurely: exitcode 155.

It seems my celery workers may have been running out of memory, as I did find traces of the dreaded oomkiller in my syslogs. I reconfigured my tasks to just be in a chain (removed all the groups and chords) so each task is run individually in sequence for each image, and the tasks all completed successfully, no matter how many images I processed.

"No CMAKE_CXX_COMPILER could be found" errror while deploying flask app on gcloud

Asked 2021-Nov-07 at 14:13

I have a flask application that I'm deploying on google cloud run. The app using a library 'face_recognition' that requires Cmake. I'm installing the CMake by running a command in DockerFile but getting an error. I don't know what it mean.

Here is my Dockerfile

# Use the official lightweight Python image.
# https://hub.docker.com/_/python
FROM python:3.9-slim

# Allow statements and log messages to immediately appear in the Knative logs
ENV PYTHONUNBUFFERED True

# Copy local code to the container image.
ENV APP_HOME /app
WORKDIR $APP_HOME
COPY . ./

# Install production dependencies.
RUN apt-get update && apt-get install -y cmake
RUN pip install --no-cache-dir -r requirements.txt
RUN pip install gunicorn

# Run the web service on container startup. Here we use the gunicorn
# webserver, with one worker process and 8 threads.
# For environments with multiple CPU cores, increase the number of workers
# to be equal to the cores available.
# Timeout is set to 0 to disable the timeouts of the workers to allow Cloud Run to handle instance scaling.
CMD exec gunicorn --bind :$PORT --workers 1 --threads 8 --timeout 0 main:app

Here is the error

The container base python:3.9-slim is very stripped down. If your application requires CMake which often implies the gcc compiler as well, you have at least two options:

Use a more feature rich base container such as debian:buster
Choose a container with those tools already configured.

Example Dockerfile to build a base container:

FROM debian:buster
RUN apt update && apt install -y gcc clang clang-tools cmake python3

You can then use that container as the base for future containers or modify the Dockerfile to include your application.

Docker debian:buster
