A program I am trying to install requires the installation of PyQt5 5.15.0 , which gives me this error. The odd thing is that the installation works fine for the latest version of PyQt5 (5.15.2), but this program requires 5.15.0 specifically.
Command Output:

I am on the latest version of pip. Any ideas on the root cause of this issue?
What helped me is upgrading pip from 20.2.3 to the latest one (in my case 21.1.1)
For Mac/Homebrew users.
The answer by #the-x is leading in the right direction. On a Mac with QT5 installed via Homebrew the qmake binary just needs to be added to the path. This can be achieved through
export PATH="/opt/homebrew/opt/qt5/bin:$PATH"
(of course depending on where the homebrew files are installed)
Running on arm with python3.6 (ubuntu18 on nvidia Xavier):
sudo apt install qt5-default
For MacOS users.
I am on Apple M1 silicon using Python 3.9.8. What worked for me was #Apaul's comment in the original question section. Install pyqt5-sip prior to pyqt5.
I also have an Intel Mac and on that machine, I do not need to do this.
Checking the binaries that PyQt5 provides in pypi for version 5.15.0 I see that it does not provide the binaries for python3.9 in windows, so pip is trying to compile using the source code which is complicated and can generate several dependency problems (for example you must have Qt 5.15 installed, etc). So my recommendation is to install a more updated version of PyQt5, for example 5.15.2 since if it provides the binaries for python3.9 on windows, in addition to being a wrapper of an LTS version of Qt then it will have solved several bugs.
python -m pip install PyQt5==5.15.2
Another solution is to use python3.8 instead of python3.9 so that you can install pyqt5 5.15.0 from pypi without problems.
Upgrading your pip enables you to install PyQt5. Personally, I had the same issue while installing PyQt6 and I upgraded my pip, and everything installed perfectly. I think both python and pip versions play an important role in installing PyQt so make sure you have later versions.
This is the command I used in Linux:
pip install --upgrade pip
Combining several answers on this question: On an Apple M1 Pro Macbook with macOS Ventura 13.0.1, with Homebrew 3.6.17 and python 3.11.0 the following commands fixed it for me (no sudo):
brew install qt5
export PATH="/opt/homebrew/opt/qt5/bin:$PATH"
python3 -m ensurepip --default-pip
pip3 install pyqt5-sip
pip3 install pyqt5 --config-settings --confirm-license= --verbose
That last step calls qmake to compile all of Qt on your M1 and takes many minutes to complete, be patient and let it finish.
Since qt5-default was not available, I installed qt5-default's dependencies
sudo apt-get install qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools
after that I installed pyqt5 via apt-get first and afterwards via pip
sudo apt-get install pyqt5-dev
pip install pyqt5
now wheel seems to work
side-note:
I am not sure if sudo apt-get install pyqt5-dev is even necessary
The error message thrown here is misleading - it's not an issue with a sipbuild.api attribute. Indeed, in this case program qmake is missing, see last line of the Python traceback. Have a look if it's installed on your system and add it to your PATH variable. Otherwise, install it. On Linux this would be done with
sudo apt-get install qt5-qmake
I had this problem on my M1 Mac using Python 3.9.12 when I was trying to install a library: pip install pixellib.
The first thing I did was: pip install pixellib --verbose to see the whole log, and there I noticed that PyQt5 was waiting for an input. So then I found someone else with that issue, and used pip install pyqt5 --config-settings --confirm-license= --verbose which took some time to compile, but worked!
I could not get any of the above solutions to work but I managed to get it working using python3.9, PyQt5=5.15.2, pip=22.0.2 and sip=6.5.0 by using sudo apt-get install PyQt5. If you need it in a virtual environment, you can manually copy the PyQt5 folder from your default /usr/lib/python3/dist-packages to the site-packages folder in your virtual environment.
To all those that are struggling with Apple M1 installation, here is a working solution, specifically addressing the problem of installing the pixellib library that depends on PyQt5 but you can apply it equally to other libs:
PyQt5 is not supported on Apple M1, it needs qt6: https://www.reddit.com/r/learnpython/comments/o4w1ut/comment/h2jele3/?utm_source=share&utm_medium=web2x&context=3 , https://www.qt.io/product/qt6
this means you need to install PyQt6: python3 -m pip install PyQt6
go to the lib you need, in my case pixellib: https://pypi.org/project/pixellib/#files and
download the wheel file
get the wheel tool: pip install wheel
unpack the wheel wheel unpack pixellib-0.7.1-py3-none-any.whl
Change its dependency of PyQt5 to PyQt6
edit pixellib-0.7.1/pixellib-0.7.1.dist-info/METADATA
pyQt5 => pyQt6
pack it back wheel pack pixellib-0.7.1
install it: pip install pixellib-0.7.1-py3-none-any.whl
test in python: `
# should work
import pixellib
P.S. thanks to Terra and ChaOS for supporting work on the project underlying this report.
I finally managed to make it works on M1/M2 Macbook Pro.
None of these answers worked for me, so I looked at brew to install pyqt.
The following command will install pyqt5 via brew:
brew install pyqt#5
Then it just worked.
This can be resolved by switching to an environment with Python >= 3.8

Trying to install:
pip install multiprocessing
Getting an error:

Anyone knows the way to fix this?
In short: Multiprocessing is already pre-installed in python 3, no need to install it.
I found an answer to my question and it's a silly one - multiprocessing is already pre-installed in my version of Python (3.5.2) by default.
It won't show up in the list of packages in Anaconda >> Environments >> root, as it's not a third party package but an internal one.
If anyone is not sure whether this applies to you, just check from multiprocessing import Pool in your Python console.
This is true of all currently supported versions of Python (2.7 and 3.x) and according to a Python maintainer/contributor multiprocessing has been part of the standard library (batteries included) since Python 2.6. https://bugs.python.org/msg326646
You won't need to do a pip install multiprocessing anymore and do NOT include it in your requirements.txt unless you are maintaining a Python 2.4/2.5 application (please migrate!). On most versions you can just import multiprocessing and you should be fine.
Instead of pip install multiprocessing type instead:
pip install multiprocess
Of course you are trying to install multiprocessing library on python3 while this library is installed on python3 by default and doesn't need to install again.
Be Lucky
pip3.5 install multiprocessing-utils
https://pypi.org/project/multiprocessing-utils/
python -m pip install multiprocessing
Use python2.7 to install multiprocessing instead of using python3.5+
Python 2.7 to 3 changed from print "Hello World" to print('Hello World') making print a function now. Judging from the error message, it looks like pip or multiprocessing is expecting python 3.
You can check your Python version using this command:
python --version
You update pip if you already have python 3 on linux:
sudo apt-get install python3-pip
For mac, you can use the equivalent homebrew command. This should allow you to use a:
pip3 install multiprocessing
everyone,
The default version of python on the Raspberry Pi 4 is 3.9. I need python 3.7. I successfully install python 3.7.4 and set it as default by adding the line alias python3='python3.7' to the bashcr file. Then I install opencv using pip3. I got: from .cv2 import *
ImportError: libImath-2_2.so.23: cannot open a shared object file: No such file or directory
I also installed it from the source and got the same result.
I investigated and found out that I need to install libilmbase12, but I got the following error message.
E: The package libilmbase12 could not be found
I appreciate any help.
I found a way. I change raspbian from bullseye to buster. Everything works fine. The problem was the compatibility of python and opencv version
You install OpenCV from bash :
sudo apt install python3-opencv
I am trying to get easyocr running on a raspberry pi 4 and could use some suggestions or help. I am using the 64 bit build from May 7th - 2021 (2021-05-07-raspios-buster-arm64.zip). When I do a fresh OS install, I execute the following commands:
sudo vi /etc/dphys-swapfile # change swapfile to 2GB
sudo raspi-config # expand the filesystem to use the entire SD card
sudo apt-get update #
sudo apt-get upgrade #
sudo apt autoremove # The following packages will be REMOVED: python-colorzero
sudo python -m pip install --upgrade pip # upgrade pip
sudo pip3 install --upgrade pip # upgrade pip3
sudo python3 -m pip install numpy --upgrade # upgrade numpy
sudo python3 -m pip install easyocr # install easyocr
I open a python3 editor and execute the following commands:
import cv2
import torch
import easyocr
reader = easyocr.Reader(['en'])
results = reader.readtext('/home/pi/Downloads/Calibration.bmp')
The last command results in an Illegal instruction error. I figured openCV was the likely culprit so I compiled it from source and tried again. I got the same error. I have tried going with a 32 bit build, but torch needs 64 bit to work. I have tried the same sequence and code through Anaconda on a windows 64 bit machine and it works without issue.
My next two attempts will be to build easyocr and/or torch from source , but I am grasping at straws here. I am really not sure how to figure out what software is causing the illegal instruction so I can hone in on that package. I would appreciate any thoughts on what I can do to get more information or thoughts on what things I can try.
Thanks a bunch.
[EDIT]I installed python3-dbg so I could run the application under gdb. When I do, the error I get is
Thread 1 "python3-dbg" received signal SIGILL, Illegal instruction. 0x0000ffffe4189fc8 in exec_blas () from
/home/[USER]/.local/lib/python3.8/site-packages/torch/lib/libtorch_cpu.so
[EDIT2]I found a git hub repository that creates wheel files (WHL) for those having illegal instruction errors like me. So far it hasn't helped. I have tried a few, but am going to use a more systematic approach. to see if I can find the right combination.
I'm trying to install yq#3 on my Mac running brew install yq#3 and I get the error:
Error: yq#3 has been disabled because it is not maintained upstream!
I see that it's there on their website at https://formulae.brew.sh/formula/yq#3#default but it doesn't seem to be supported anymore.
I still need to install it since our projects at work are using this specific version.
The only way that I'm thinking about is downloading the source code, building it myself, and adding it to the path but I'm thinking that there might be a simpler solution.
Any suggestion?
Thanks!
From yq github, you can install a binary by running:
wget https://github.com/mikefarah/yq/releases/download/3.4.1/yq_darwin_amd64 -O /usr/local/bin/yq &&\
chmod +x /usr/local/bin/yq
3.4.1 is the latest 3 version, darwin_amd64 is the Mac package (don't worry about having an Intel machine and installing the package that says AMD, the name comes from something about AMD invented the 64-bit instruction set).
I have been trying some different java compilers over the weekend and decided to stick with javac this morning. I then proceeded to clean up the mess that was caused by my testing and removed every last trace of java and did a fresh 'apt-get install openjdk-6-jdk' after autoremove and autoclean.
The following weirdness was then encountered:
tarskin#5-PARA-11-0120:~$ javac
The program 'javac' can be found in the following packages:
* openjdk-6-jdk
* ecj
* gcj-4.4-jdk
* gcj-4.6-jdk
* gcj-4.5-jdk
* openjdk-7-jdk
Try: sudo apt-get install <selected package>
I had allready installed openjdk but i tried it anyhow yielding:
tarskin#5-PARA-11-0120:~$ sudo apt-get install openjdk-6-jdk
[sudo] password for tarskin:
Reading package lists... Done
Building dependency tree
Reading state information... Done
openjdk-6-jdk is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
tarskin#5-PARA-11-0120:~$
I know i must be doing something stupid but I have no idea what, if anyone else could give a pointer in the right direction that would be very much appreciated...
Cheers
EDIT: Found some other weird aspects about the 'new' instance of my java distro, it doesn't seem to recognise for example 'Pattern' or 'Matcher' that should be coming from the regex import shrugs.
TL;DR: install java-1.6.0-openjdk-devel
I had a similar issue on Fedora, but used rpm -q -l to list the contents of the (pre-installed) java-1.6.0-openjdk package, and discovered that it doesn't include javac. It is in fact only a JRE, not a JDK, as implied by the installation instructions on http://openjdk.java.net/install/ . To get javac, I installed java-1.6.0-openjdk-devel . Not exactly what I expected, because the usual packaging conventions would indicate that is the package for doing openjdk development (i.e., working on the JVM), not for developing programs with it.
Basically, openjdk's package naming doesn't follow either standard Java conventions (would require calling it a JRE somewhere), or standard Linux packaging conventions (using -devel indicates it is used for developing the package w/o -devel itself).
As per http://openjdk.java.net/install/, to install the OpenJDK-6 JRE only:
$ sudo apt-get install openjdk-6-jre
To install the full JDK:
$ sudo apt-get install openjdk-6-jdk
Check /etc/alternatives and /usr/bin. One or both will contain links to old Java versions which you had installed. When those links are broken, you can get the error message above.
To update the links after installing a new version of Java, try update-alternatives
First to check if javac is installed try to look for that file:
1. locate javac
2. or find / -name javac
And also you can check at this website with instrucions on how to install java on Ubuntu (i suppose you are on ubuntu):
http://openjdk.java.net/install/
You can also check:
http://packages.ubuntu.com/hardy/i386/openjdk-6-jdk/filelist for the files installed by the pacakge, and you can notice that javac should be installed.
Maybe you also need to run:
Open the terminal and run this command to install OpenJDK 7.0 on Ubuntu Oneiric:
sudo update-alternatives --config java
