After upgrading to python-pyqt5 5.12-2 I get this error when I try to import from QtWidgets
from PyQt5.QtWidgets import *
Error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'PyQt5.sip'
Any idea on how can I solve this issue?
The reason is a backward incompatible change in PyQt-5.11
In geoptics this fix works on old and new versions:
try:
# new location for sip
# https://www.riverbankcomputing.com/static/Docs/PyQt5/incompatibilities.html#pyqt-v5-11
from PyQt5 import sip
except ImportError:
import sip
As suggested here pyuic5 - ModuleNotFoundError: No module named PyQt5.sip
Try uninstalling and re-installing all PyQt related libraries:
pip uninstall PyQt5
pip uninstall PyQt5-sip
pip uninstall PyQtWebEngine
Then install them again, this will fix:
ModuleNotFoundError: No module named 'PyQt5.sip'
ModuleNotFoundError: No module named 'PyQt5.QtWebEngineWidgets'
PPS.:If you got problems uninstalling the libraries, go to your Python folder, like C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python<PYTHON-VERSION>\Lib\site-packages and manually delete the PyQt folders, them uninstall everything and install again (Make sure you have the latest Python version and upgraded your pip too)
If you're building sip and PyQt5 from source using make files, make sure to check PyQt5 install docs. In particular,
Note
When building PyQt5 v5.11 or later you must configure SIP to create a
private copy of the sip module using a command line similar to the
following:
python configure.py --sip-module PyQt5.sip
If you already have SIP installed and you just want to build and
install the private copy of the module then add the --no-tools option.
You should add PyQt5.sip to hidden imports; that should solve the issue.
I repaired this problem
This problem occurred when upgrading pyqt5 version 5.15.0
There was no problem when I reverted to the previous version.
I have
python -V: 3.7.4
PYQT5 5.14.1 and PYSIDE 5.14.1 works fine
In addition to the answer provided by Tadeu (https://stackoverflow.com/a/58880976/12455023) I would also suggest checking version of your libraries to make sure that they match.
Use pip show <library_name>
This will help you to make sure that no earlier installation is conflicting with your current installation.
In place of library_name use PyQt5, PyQt5-sip, PyQtWebEngine. If any of them is present in the system, then use pip uninstall <library_name>==<version_number> to remove that library.
Once you made sure that no other versions of these libraries are there, then you can reinstall the preferred version of that library.

What version of Python are you running? In order to both successfully import and run the Tensorflow module, you must have the 64 bit version of Python installed. If you are using the latest version of Python, which to the best of my knowledge is 3.8.2, completely uninstall that version of Python, and downgrade to the latest Python version with 64 bit support.
If you follow the output of pip --version to find where your anaconda files are located, you can find the anaconda python executable, usually about two directory levels higher (if pip is in C:\example\anaconda\lib\site-packages, then python is probably in C:\example\anaconda) and use a full path to that python executable to run the file like C:\example\anaconda\python app.py. Or you could update your path environment variable to replace C:\Users\antoi\AppData\Local\Microsoft\WindowsApps\ with the directory containing the anaconda python executable
I've had this same exact issue (but on macOS) several times before I realized what was wrong, and I've seen several others have this issue too. I wish there was a way Python could somehow better regulate this to make sure the default executables for pip and python are always in sync
Tried to run a script I wrote yesterday again today and ran into this:
ImportError: cannot import name 'Repo' from 'git' (/usr/local/lib/python3.7/site-packages/git/__init__.py)
I am at a complete loss. On a new computer so the only thing different install wise would have been that I installed pycharm. I am currently trying to run through bash shell on a mac. The exact code was running as excepted earlier, no code changes.
Things I have tried:
uninstalling/reinstalling python
uninstalling/reinstalling pip
uninstalling/reinstalling gitpython
Running on:
mac catalina
python version 3.7.6
pip version 20.0.1
As a side note, the script works as intended until the automated git push. Wondering if I should just make the os calls myself and not worry about this?
I really dont understand what I did/am doing wrong here.
EDIT:
Again, sorry as this is my first mac computer. I did a brew uninstall of python3 and reinstalled through the app store to 3.8.
ImportError: cannot import name 'is_cygwin_git' from partially initialized module 'git.util' (most likely due to a circular import) (/Library/Frameworks/Python.framework/
I know cygwin is for windows, but I figured I'd play along and trying a pip install pycygwin.
Install threw an error asking for cython, so I did another pip install and tried again. The pycygwin then complained gcc was missing so I did a brew install of gcc. With gcc installed and correctly on path, it still says it cant find it and exits with
build/cygwin/_cygwin.c:611:10: fatal error: 'sys/cygwin.h' file not found
#include <sys/cygwin.h>
^~~~~~~~~~~~~~
1 error generated.
error: command 'gcc' failed with exit status 1
Thinking I might just try a different package manager? Currently, an attempt to rerun the script yeilds
ImportError: cannot import name 'Repo' from partially initialized module 'git' (most likely due to a circular import)
To which I investigated but I shouldn't have any overlapping dependancies.
On the script throwing the error I'm using:
import csv
import yaml
import os
from git import Repo
and on the wrapper I made and imported, I'm using:
import subprocess
import re
Will update if I get any further on this, would love some suggestions.
EDIT:
Importing using just import git works throws a different error, like the python is trying to get itself?
ImportError: cannot import name '<file name>' from '<file name>'
If I change the file name and try to run it, it comes backs with:
ImportError: cannot import name '<old file name>' from '<old file name>'
***FIXED****
Uninstall of python through homebrew
Reinstall of python through mac app store
Uninstall/Reinstall of modules through pip
Saving the file under a new name and deleting the old one
Still have absolutely no idea why/how this happened but the above worked for me. If anyone knows why something like this can happen, I would love to know. Cheers.
I am trying to build an app in PyQt5 (version 5.6+) in Python 3.6. It contains a web browser, using QtWebEngineWidgets.
It works fine on Mac, however, there are problems on Windows.
When I run the code on Windows and import the module:
from PyQt5 import QtWebEngineWidgets
I get the following error:
ImportError: cannot import name 'QtWebEngineWidgets'
Now, reading some forums it looks like PyQt5.QtWebEngineWidgets is not available for Windows, yet. Is it correct?
How can I have a web browser window, then?
I found online I could use QtWebKit, but according to here it seems QtWebKit was removed in Qt5.6.
So what? Do I have to downgrade PyQt version?
I can't go under 5.6 in Python 3.6 anyway. Do I have to change Python version as well?
you can try one of these solution ,
install old version :
pip install PyQt5==5.11.3
or install :
pip install PyQtWebEngine
u can download PyQt5.6 from here:
https://sourceforge.net/projects/pyqt/files/PyQt5/PyQt-5.6
QtWebKit got deprecated upstream in Qt 5.5 and removed in 5.6. Beacuse The QtWebEngineWidgets module is better than QtWebkit.
The example directory has many examples about QtWebEngineWidgets
Yes, its possible to use QtWebEngineWidgets on Windows.
I want to use Gtk with python under windows. I already have Anaconda installed on windows. In order not to mess up everything and to have some easiness uninstalling/reinstalling, I would like to have a virtual env created with conda, working with that Gtk installation. But I don't seems to be able to make it work.
Here is my process. I first create a raw Ananconda virtual env with
conda create -n gtk-exporter python
The virtual environment is located at C:\Anaconda3\envs\gtk-exporter.
I then download the latest windows installer for PyGObject at http://sourceforge.net/projects/pygobjectwin32/files/?source=navbar
I extract and execute the installer and tell it to use a portable python install at C:\Anaconda3\envs\gtk-exporter. I only select Base, GTK and Glade for installation. The installation finished in a second and says it's successful.
Then within windows' shell, I activate the new environment with activate gtk-exporter. However when I try to import gtk, it fails, not finding gi.repository.
>>> from gi.repository import Gtk
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'gi'
What's wrong here ? C:\Anaconda3\envs\gtk-exporter\Lib\site-package contains a folder gnome with a lot of stuff including *.dlls, *.exe's and unix-looking folders like etc, lib or share, but I don't see a init.py or something pythonic. Am I missing a step.
Thank you for your help !
The problem was that I used python 3.5, whereas it is not supported. The installer should not have allowed me to install with python 3.5. I filed a bug report to signal it.
I solved the problem by uninstalling python 3.5 and installing python 3.4.
I am trying to install NumPy from a wheel (.whl) file. I get the error:
numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl is not a supported wheel on this platform.
Details:
Windows 8.1 pro x64, elevated command prompt
Python 3.4.2
Package NumPy from Gohlke's site
File numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl copied in the pip.exe folder
The log file shows:

pip.exceptions.UnsupportedWheel: numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl is not a supported wheel on this platform.
What is wrong?
Short answer: rename the file to numpy-1.9.1%2Bmkl-cp34-none-win32.whl to install it.
You can check what tags your pip tool accepts for installation by running:
import pip; print(pip.pep425tags.get_supported())
In this case pip is incorrectly detecting your operating system to be 32-bits and the file you're trying to install was win_amd64 in its filename.
If you rename the file to numpy-1.9.1%2Bmkl-cp34-none-win32.whl (which now contains the tags that are considered supported) then you can install the package. It's a trick because the file is still built for 64-bits but this allows you to install the package as intended.
After several tests I think the problem is "win32" or "amd64" itself. I tried replacing those two with "any" and it worked.
In my case, the workaround to install gohlke packages on Python (3.4.4 (AMD64)) was to change the "cp34m" part rather than the "win*" parts in previous answers:
python -c "import pip; print(pip.pep425tags.get_supported())":
[('cp34', 'none', 'win_amd64'), ('py3', 'none', 'win_amd64'),
('cp34', 'none', 'any'), ...
ls -ld *:
matplotlib-2.0.0b3-cp34-cp34m-win_amd64.whl
numpy-1.11.1+mkl-cp34-cp34m-win_amd64.whl
pandas-0.18.1-cp34-cp34m-win_amd64.whl
Change the above names to:
matplotlib-2.0.0b3-cp34-none-win_amd64.whl
numpy-1.11.1+mkl-cp34-none-win_amd64.whl
pandas-0.18.1-cp34-none-win_amd64.whl
For example, pip install matplotlib-2.0.0b3-cp34-none-win_amd64.whl
Processing ...
...Successfully installed matplotlib-2.0.0b3
To add to the list of other possible solutions, I had to upgrade pip itself. The latest binary from Gholke's site had the "cp27m" tag, which didn't show up when I checked the pip tags using:
import pip; print(pip.pep425tags.get_supported())
After I upgraded pip, the wheel didn't work, but just doing a regular pip install numpy worked.
If you have, say, Python 3.4 installed, make sure to install the -cp34- version of the wheel and not -cp35-.
The current WinPython package manager need a two-characters fix to accept to recognize the new NumPy + mkl 'wheel'.

As a workaround, uninstall the NumPy package:
pip uninstall numpy
Then install it again from cache:
pip install numpy
I had the same problem with several packages after upgrading from 3.4.1 to 3.4.2.
Navigate to the directory where your 'pip.py' sits and then type following on the Windows command line:
..\python.exe pip.py install name_of_package.whl
This should work.
I had the same problem and tried to work it out with the suggested solutions.
I changed win64 to win32 and it didn't work either. But then I changed the name to original and this time it worked! The only extra thing I did was to go offline. That's so strange.
This has nothing to do with your operating system. Uninstall Python 32-bit and install Python 64-bit rather or alternatively find a 32-bit wheel file.
