I was trying to pip install pandas==1.2.5
And have the issue
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for pandas
Failed to build pandas
ERROR: Could not build wheels for pandas, which is required to install pyproject.toml-based projects
1.Updated pip to the latest version: pip install --upgrade pip
2.Tried installing the dependencies for pandas: pip install numpy matplotlib
3.Tried installing pandas again: pip install pandas==1.2.5
I was trying to install some packages but it gives me an error saying that my whl version is not supported
my commands -
!pip3 install folium==0.2.1
!pip3 install --upgrade pip==20.0.2 setuptools==46.1.3
!pip3 install --upgrade --force-reinstall -e .
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.

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
available. You should consider upgrading via the 'python -m pip
install --upgrade pip' command.
I ran in command prompt with admin privileges following
python -m pip install --upgrade pip
Now "pip install opencv-python" works
I am installing scikit-image using pip install scikit-image. I get this error:
Failed building wheel for scikit-image
What is the command to install scikit-image using wheel?
I see references to pip install SomePackage-1.0-py2.py3-none-any.whl but I didn't understand what this does.
First do this
python -m pip install --upgrade pip
Then install scipy
Then install numpy
pip install numpy
Somehow pip --upgrade doesn't upgrade any packages.
I'm on OSX El Capitan (10.11.3) and installed python using brew install python
Python: /usr/local/bin/python# -> ../Cellar/python/2.7.11/bin/python
Pip: /usr/local/bin/pip# -> ../Cellar/python/2.7.11/bin/pip
After successful install I run pip install --upgrade pip.
Full output:
$ pip install --upgrade pip
Collecting pip

You are using pip version 8.0.2, however version 8.1.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Why doesn't pip install the new version?
Update
I think it has something to do with my ~/.pydistutils.cfg file which fixes the DistutilsOptionError: must supply either home or prefix/exec-prefix -- not both error when running pip. I followed these instructions

Getting annoyed by things not working I created a new OSX profile. In the new profile everything was working fine so after investigating further I found a file ~/Library/Application\ Support/pip/pip.conf in my main profile containing:
[global]
target=/usr/local/lib/python2.7/site-packages
I don't know how it got there but removing it resolved the issue.
This also resolved the need for the ~/.pydistutils.cfg file.
