image = face_recognition.load_image_file("My_Image.png")
face_locations = face_recognition.face_locations(image)

When I run above code, I've found following error message.

My python version is Python 3.7.1 and pip is pip 19.0.3 from /Library/Python/2.7/site-packages/pip (python 2.7)
Install Cmake with:
sudo apt install cmake
And for python3 don't use pip alone, use pip3 to install future python3 modules:
pip3 install face_recognition
I was facing same issue, but then it solved through following steps:
Step 1: Download Microsoft Visual Studio 2015 or newer (check if build tools are enough).
Step 2: Download cmake (pip install cmake)
Step 3: Install dlib (pip install dlib)
Step 4: Install face-recognition (pip install face-recognition)
But install it in specific environment that will be used later for face_recognition code (In conda: activate environment name).
Reference:
https://www.youtube.com/watch?v=oSQAXMgwLFo
For everyone who still found error when installing this step, I will give a brief requirements for your system.
Python3.9 [the most important]
Download dlib (this)
Next, after the above requirement fulfilled, do this.
pip install cmake
pip install dlib-19.23.0-cp39-cp39-win_amd64.whl
pip install opencv-python
pip install face_recognition
Bonus, in my case, I got error with the pillow library so you need to reinstall it, using these steps.
pip uninstall pillow
pip install Pillow
Well, I hope this will help, thanks.
This worked for me...
pip install CMake==3.22.2
pip install dlib==19.18.0
pip install face_recognition

I can't install the regressors package with pip install regressors command in Windows 11.
The returned error is:
python setup.py egg_info did not run successfully.
│ exit code: 1
╰─> [32 lines of output]
I have upgraded below libraries/dependencies.
pip install --upgrade pip
pip install --upgrade setuptools
pip install ez_setup
Tried many suggestions from Web, none of them worked Any help would be
appreciated,
I fixed a similar error when installing a different package by downgrading my version of setup tools:
pip install --upgrade pip setuptools==57.5.0
pip install {package}
I got to this solution from this: https://github.com/Thibauth/python-pushover/issues/42
Clone this library into your project, remove use_2to3 argument from setup.py in regressors package you cloned then install it with pip using below command and after that you can use this package in your project:
pip install -e ./name_of_your_clone_instance
I was trying to install OpenCV4 in a docker on jetson nano. It has jetpack 4.4 s os. The docker was successfully created and Tensorflow is running but while installing OpenCV using pip it is showing CMake error.

ERROR: Failed building wheel for opencv-python

ERROR: Could not build wheels for opencv-python which use PEP 517 and cannot be installed directly
I had the same problem and i did this,
pip install --upgrade pip setuptools wheel
then install opencv again,
pip install opencv-python
this worked for me
If after
pip install --upgrade pip setuptools wheel
you still have the same error,
You can try to specify the older version of OpenCV to install.
Ex.
pip3 install opencv-python==3.4.13.47
Yes .. Finally found a work around.
Follow this https://github.com/mdegans/nano_build_opencv and build from source and finally gets installed.
PS: It may take a bit long for building, for me it took 10 Hrs :P.
Happy Image-Processing..
I had a similar problem and what solved it for me was not to use python:3-alpine but python:3.8-slim. E.g.:
FROM python:3.8-slim
WORKDIR /usr/src/app
RUN apt update
RUN apt -y install build-essential libwrap0-dev libssl-dev libc-ares-dev uuid-dev xsltproc
RUN apt-get update -qq \
&& apt-get install --no-install-recommends --yes \
build-essential \
gcc \
python3-dev \
mosquitto \
mosquitto-clients
RUN pip3 install --upgrade pip setuptools wheel
RUN python3 -m pip install --no-cache-dir \
numpy scipy matplotlib scikit-build opencv-contrib-python-headless \
influxdb paho-mqtt configparser Pillow \
qrcode
worked finally for me.
please check your python specifications:
- opencv -> python[
version='
>=2.7,<2.8.0a0
>=3.5,<3.6.0a0
>=3.6,<3.7.0a0
>=3.7,<3.8.0a0']
I handled it by reinstalling python3 from scratch in my MacBook:
brew reinstall python#3.9
I also reinstalled numpy and matplotlib packages experimentally.
pip3 install numpy
pip3 install matplotlib
pip3 install opencv-contrib-python
The versions:
macOS Mojave 10.14.5
Python 3.9.7
OpenCV 4.5.3
OpenCV's version is 4.5.3 by this way:
import cv2
print(cv2.__version__)
But by "pip list", it shows "opencv-contrib-python 3.4.9.31".
if you are trying to install opencv in your raspberrypi 3B, Use following steps:
sudo raspi-config
advanced -- expand filesystem
reboot your pi
Open your raspi terminal and do following stuff:
use command: sudo apt-get update
use command: sudo apt-get upgrade
check your python version and upgarde it to latest one
install pip and upgrade pip
use command: mkdir project
use command: cd project
create virtual environment
activate virtual environment
install dependencies ,can get dependencies from https://singleboardbytes.com/647/install-opencv-raspberry-pi-4.htm
if error in installing libdhf5-dev
use command: sudo apt-get install python3-h5py and reinstall libdhf5-dev
use command: pip install scikit-build
use command: pip install cython
before installing opencv ,make sure you are in virtual environment or
activate environment
use command: pip install --no-cache-dir opencv-contrib-python==4.5.3.56
Remember to use mentioned version...
Thank You...
I came across similiar situation
I had error
Failed to build opencv-python ERROR: Could not build wheels for
opencv-python which use PEP 517 and cannot be installed directly
WARNING: You are using pip version 19.2.3, however version 22.0.4 is

I ran in command prompt with admin privileges following

Now "pip install opencv-python" works
I'm getting an error when trying to install dlib on Python 3.7 on macOS with
pip3 install dlib
I have installed CMake, so that is not the problem.
I'm getting these error messages:
Failed building wheel for dlib
and
Command "/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7 -u -c "import setuptools, tokenize;__file__='/private/var/folders/j2/nvk5521j2vn9s1w95_0vlwkm0000gn/T/pip-install-ls2e_3mr/dlib/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /private/var/folders/j2/nvk5521j2vn9s1w95_0vlwkm0000gn/T/pip-record-hy3hu262/install-record.txt --single-version-externally-managed --compile"

at the end in red. The reason I need dlib is to install face_recognition.
I think there's more to the error message and it's probably related to CMake, either it's not installed properly or it's not compatible with the pip3 install dlib.
I suggest using Homebrew to install Python3 (which includes pip3) and CMake. Homebrew manages the installation of packages, tools, libraries that might depend on system-related tools, paths, etc. It also prevents you from having to use sudo to install stuff on your system.
Install Homebrew
See the "Install Homebrew" section of https://brew.sh/
Basically:
$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Install Python3 (and pip3) using Homebrew
See https://docs.brew.sh/Homebrew-and-Python
See Homebrew's formula for the latest Python3 (python3.7, python3.8, python3.9)
Basically do one of the following:
$ brew install python#3.7 # or python#3.8 or python#3.9
$ brew install python#3 # get whichever is the latest version
Check Python installation
$ python3 -V
$ python3 -m pip -V
Install CMake using Homebrew
See https://formulae.brew.sh/formula/cmake
Basically:
$ brew install cmake
Check CMake installation
$ brew info cmake
$ cmake --version
Finally, install dlib with pip
$ python3 -m pip install dlib
If you don't want to use Homebrew (for some reason), you can try installing CMake for Mac directly using the installers (dmg or tar.gz) from here: https://cmake.org/download/.
Install Homebrew from here
A bunch of dependencies are needed for dlib:
brew install cmake
brew install boost
brew install boost-python
brew install dlib
pip3 install numpy
pip3 install scipy
pip3 install scikit-image
pip3 install dlib
If this does not work, try:
python3 -m pip install dlib
dlib is dependent on cmake so you need to install that first.
You just need to run following commands on your terminal:
$ brew install cmake
$ pip install cmake
$ brew install dlib
$ pip install dlib
You can install the conda-forge Dlib package by running
conda install -c conda-forge dlib
Conda-forge has made sure to resolve all the dependency conflicts, so I had no issues with the installation. They have pre-built binaries for Windows, Linux, and Mac OS, and Python 2.7 through 3.8. The current package (at the time of this writing) is based on Dlib v19.19.
$ pip3 install --upgrade pip
$ pip3 install global
$ pip3 install cmake
$ pip3 install dlib
$ brew install dlib
$ sudo pip install dlib
The only thing you need to do, I guess, is run pip3 install dlib with sudo.
sudo pip3 install dlib
Not sure whats going on here but I am getting an error every time I try to install something using pip I get the following error:
Command "/usr/bin/python -c "import setuptools, tokenize;__file__='/private/var/folders/b0/5843zgyj1yz3b8q2l7wrtj8h0000gn/T/pip-build-V4hy8S/PySocks/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /var/folders/b0/5843zgyj1yz3b8q2l7wrtj8h0000gn/T/pip-bIOl7C-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/var/folders/b0/5843zgyj1yz3b8q2l7wrtj8h0000gn/T/pip-build-V4hy8S/PySocks
Try
sudo pip install -U setuptools
If this doesn't solve your problem then
Firstly, you need the python-dev package because Pillow needs compile headers defined.
sudo apt-get install python-dev
On Ubuntu 14.04 you need few extra packages to get pillow working. Install all of them with the command:
sudo apt-get install libtiff5-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk
Seems that your PiP can't access Setuptools as per the "import setuptools" in the error. Try the below first then try running your pip install again.
sudo pip install -U setuptools
Solution from Github Issue
Launch the command prompt with 'run as administrator' rights before installing.
then try the script -
pip install package_name_here
if error is thrown,then import setup tools
pip install -U setuptools
if again error thrown then upgrade your pip installer using this script(personally worked for me)
python -m pip install --upgrade pip
I had the same problem on Windows Git Bash but installing setuptools did not fix it. Then I noticed another error message further up:
building 'twisted.test.raiser' extension error: Microsoft Visual C++ 14.0 is
required. Get it with "Microsoft Visual C++ Build Tools":
http://landinghub.visualstudio.com/visual-cpp-build-tools
That link was dead but ultimately this page had a link to the correct download: https://wiki.python.org/moin/WindowsCompilers
I installed Microsoft Build Tools for Visual Studio 2017 and that resolved it.
It majorly depends on the type of packages you suppose to install.
Frequently its failing due to the missing of
libsasl2-dev a package for authentication abstraction library which use in the Ubuntu version
First, install:
sudo apt-get install libsasl2-dev
then run:
pip install <<\package_name>>
first run as superuser:
sudo su
then :
pip install PyOpenGL PyOpenGL_accelerate
If you get this error on Windows, like I did, then just run the command-line tool (cmd.exe or Powershell) as Administrator and try again.
I have Python 2.7.9 on windows 7 64-bits. I'm trying to install scipy using pip. I used pip install scipy but I get the following error :
Command "C:\Python27\python.exe -c "import setuptools, tokenize;__file__='c:\\us
ers\\admin\\appdata\\local\\temp\\pip-build-xpl5cw\\scipy\\setup.py';exec(compil

rd\install-record.txt --single-version-externally-managed --compile" failed with
error code 1 in c:\users\admin\appdata\local\temp\pip-build-xpl5cw\scipy
I searched on google and stackoverflow for solutions but nothing worked. I tried upgrading pip and it didn't work too.
Here are my installed packages and their versions :
httplib2 (0.9.1)
nltk (3.0.3)
nose (1.3.7)
numpy (1.9.2)
pip (7.0.3)
pytz (2015.4)
scikit-learn (0.16.1)
setuptools (17.1.1)
six (1.9.0)
twilio (4.4.0)
wheel (0.24.0)
I'm on Ubuntu 14.04. I tried installing through pip which kept on failing with error code 1 or took forever to finish (never finished actually!).
However, the following command worked without a hitch:
sudo apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose
Reference: http://www.scipy.org/install.html
On Windows, you'll need to use the unofficial precompiled binaries:
http://www.lfd.uci.edu/~gohlke/pythonlibs/
Select the version matching your architecture and Python version.
Installing setuptools made it work for me (Mac OS)
pip install -U pip setuptools
I also had the same error when installing scipy.
Then I downloaded and installed MiniConda. And then I used the below command to install pytables.
conda install -c conda-forge scipy
Please refer the below screenshot.
On windows you can check below command:
python -m pip install psycopg2
