Since PIL.ImageGrab() gave me some problems, I read further into the topic and it seems that gtk is the better solution for making Screenshots.
But I don't understand which packages are actually working and which are deprecated.
trying
pip install pygtk
gives me
ERROR: Could not import dsextras module: Make sure you have installed pygobject.
pygobject doesn't exist, installing gobject doesn't help.
I tried some variants of the module name like python3- or just 3 at the end, but I don't seem to get the right one.
The full chat session about this is here. The original solution can be read here, especially the comment made by #cdarke.
So anyway, the solution is to use Python3.5 intead of 3.6 or newer, at least until MSYS2 is updated.
As a sidenote, you really don't want to use pygtk (which is based on Gtk2). Use pygobject like such:
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
for GTK+, you have to do the following:
from gi.repository import Gtk
and not:
import gtk

I try since multiple days to install solaris (https://github.com/CosmiQ/solaris) locally, on google colab or on renkulab (https://renkulab.io/). Up to now, without any luck. I tried on all platform different approaches:
Creating a conda environment (as recommended by the authors)
Directly through pip
And also cloning the repository and access the folders and functions directly
All of these approaches failed so far. Mostly there is a wheel building error for GDAL. Which i have installed first. I do not find any proper documentation or other failure descriptions which makes me question myself... Maybe here someone has experience with this library?
I highly appreciate every hint.
Thanks a lot
Colab Setup
I can get it set up in Colab with the following:
First Cell: Install Mamba/Conda
!pip install -q condacolab
import condacolab
condacolab.install()
This will trigger a runtime restart - it does this on purpose.
Second Cell: Install Solaris prerequisites
I'm assuming we want the GPU-enabled version. If not, there is another YAML in the solaris repository for a CPU-only environment.
!wget https://raw.githubusercontent.com/CosmiQ/solaris/main/environment-gpu.yml
!mamba env update -n base -f environment-gpu.yml
Manually restart the runtime after this completes!
Third Cell: Install Solaris
!pip install solaris
That should be it. Following these steps, I could import the module and use the entrypoints, e.g.,
Module import ✅
import solaris
Example entrypoint ✅
!make_masks -h
There were some future deprecation warnings from NumPy about some syntax in the TensorFlow code, but otherwise, seems functional. However, I don't personally use this tool, so I don't know if there is more to verify.
I have been using my computer,
running experiments with Python 2.7 and configparser worked fine!
Today it decided to stop working
and I changed configparser to ConfigParser, and
it worked! Still on Python 2.7.
Any idea how to revert that? Make it work again with configparser?
I do not want to go through all my code
and change them. On top of that it is irritating that
all of a sudden it decided to stop working!
Thanks
You can import the module under a different name:
import ConfigParser as configparser
This change was introduced in Python 3.0 back in 2007, it is documented in the "What's New In Python 3.0" as well as the PEP 3108 document in section "PEP 8 violations". A few modules, including ConfigParser, were renamed to comply with Python's PEP8 style guide. Quote:
PEP 8 specifies that modules "should have short, all-lowercase names" where "underscores can be used ... if it improves readability".
I am on windows 64bit, I have installed anaconda, and managed to create an environment with python 2.7
I have numpy, pylearn2, theano, and every package is built properly
I have been able to import all these modules, however I get some very esoteric messages when I try to complete the model, like
ImportError: Could not import pylearn2.models.softmax_regression but could import pylearn2.models. Original exception: No module named dnn
Then I tried to actually find the package in the installation, but inside the cuda folder, there is no module named dnn. Looking at github, I see that it should be there.
Why is theano missing modules? I installed using conda install theano, and it gave some suggestions, I have managed to pick the correct one.
I have uninstalled and installed theano many time, I can import it but I can never get the proper modules.
What is going wrong?
Ok, after a few days of search, it seems like Theano installed from anaconda is missing a lot of modules. However, installing theano by cloning the repository with
pip install --upgrade --no-deps git+git://github.com/Theano/Theano.git
seems to resolve the issue. Since windows normally does not have git, it can be easily installed (seems to take care of the environment's path variable) from here

I am pretty new to programming, and have never used Zbar before. I am trying to write a simple script that will allow me to import Zbar and use it to decode a barcode image. I already have a script set up to decode text from images that uses Pytesseract and Tesseract OCR, but I need to be able to decode barcodes as well. I have Windows 7 32 bit, and and am using Python 3.4. I have already installed Zbar and have used it from the command line successfully to decode their barcode sample. I have tried using >pip install zbar, but I keep getting the error:
"fatal error C1083: Cannot open include file: 'zbar.h': No such file or directory
error: command 'C:\Program Files\Microsoft Visual Studio 10.0\VC\BIN\cl.exe' failed with exit status 2"
Getting the pytesseract OCR was painless but I have wasted a lot of time on this barcode portion of it, any help or alternatives would be much appreciated.
Seven months later you accepted the best answer, a simple solution for
python3.4+ on Windows OS appeared. A ctypes-based wrapper around the zbar barcode reader, a package named pyzbar. If you are on Linux, you need to install libzbar0 but you said you are using Windows and the zbar library is included as dll with the Windows Python wheels. Today, all you need to do is launch:
pip install pyzbar
References for the package:
https://pypi.python.org/pypi/pyzbar
https://github.com/NaturalHistoryMuseum/pyzbar/
I thought I'd share my explorations and discoveries in relation to this problem, even though #ltadams21 has found a workaround.
The short answer: You can't. The zbar module is only compatible with Python 2. The incompatibilities are at the level of the Python C API, which is deep magic beyond my ken.
There's a bug report for this. In the meantime, use the os.system workaround that #ltadams21 posted, or maybe try zbarlight instead? (I haven't tried it myself, because it says it only reads QR codes, and I need something that reads EAN barcodes.)
The long answer: You can follow along with these steps, which represent my best efforts to get it working, but (spoiler alert) it still won't work at the end.
(Re)install zbar for Windows (zbar-0.10-setup.exe), making sure to tick the "Development Headers and Libraries" option.
Download and extract the zbar Python package (zbar-0.10.tar.bz2).
Open setup.py in your preferred text editor.
Scroll to the bottom, find the line that starts libraries, and insert a new line below it, like so (checking that the path is the same on your system as it is on mine):
libraries = [ 'zbar' ],
include_dirs = ['C:/Program Files (x86)/ZBar/include'],
Open a command prompt inside the extracted package and run python setup.py install.
Observe that the new errors now relate to PyIntObject and PyInt_Type. Discover that these are Python 2-only objects.
If desperate, try to re-#define them to use PyLongObject and PyLong_Type instead. Fail, because of course it's not that easy. Bang head against keyboard (gently).
Give up, and use the os.system workaround that #ltadams21 posted.
Forget wrestling with all of the wrappers. The easiest solution for me was to simply use
import os
os.system(r'D:\Winapps\Zbar\bin\zbarimg.exe -d d:\Winapps\Zbar\Examples
\barcode.png')
Worked instantly. Hope this helps anyone else struggling with that issue.
As of November 2016, there is the package pyzbar. To import Zbar for python3.4+ on Windows OS, all you need to do is launch
pip install pyzbar
This is possible because pyzbar is a ctypes-based wrapper around the zbar library that is included as dll with the Windows Python wheels.
The ZBar for python says you need to have the ZBar library installed for it to work. http://zbar.sourceforge.net/download.html
I found an easy solution for 3.4+. First install pyzbar
pip install pyzbar.
Then the below should work
import pyqrcode
from pyzbar.pyzbar import decode
from PIL import Image
qr = pyqrcode.create("HORN O.K. PLEASE.")
qr.png("horn.png", scale=6)
decode(Image.open('horn.png'))
print(qr.data)
I know that similar- questions about installing modules in Portable Python have been
asked but I have looked at all of them and another website. I didn't have success.
For me, I wanted to install Pygame on Portable Python 3.2.5.1 (on a memory stick). I nearly
managed to install it successfully but when I typed import pygame into the shell window,
there was a weird error in one of the files, displayed in the shell. See image below:
Update: Portable Python at time of writing has been discontinued (not being developed anymore)
and there are other alternatives available in suggested links on their website or internet search
engine query results. I have managed to add the Pygame Python module to my version
of one of these continuing projects so this question is not of use to me anymore.
I had this same problem today. I may have managed it. This is what I did:
I installed pygame to an empty folder so I could see all the things it needed. this was two folders:
Include>pygame and
Lib>site-packages
I went to Lib>site-packages and copied all the things there, then pasted them into
G:\Portable Python 3.2.5.1\App\Lib\site-packages
I also copied all the things in:
G:\Include\pygame
and pasted them into:
G:\Portable Python 3.2.5.1\App\include
from a quick play, this seems to work.
Although it isn't really the proper answer I was looking for a while ago when I posted the question (how to install Pygame on Portable Python 3.2.5.1), I have a possible answer for my question that could work.
It is possible (although I haven't personally tested it yet) run a Python
program using Portable Python and with the Pygame library folder stored in the directory the program is stored in. Python's module search path includes the current directory (of the running file) so import pygame would import it.
This question is old and maybe this is a possibility that was not possible at this time but simply:
From a command prompt go to your Portable Python's python.exe folder with cd <path to Portable Python>\App\Python,
Run: .\python.exe -m pip install pygame,
Now you have pygame module installed, you can check in your <path to Portable Python>\App\Python\Lib\site-packages that you have now pygame.
Note: I used Portable Python from here, version 3.10.5 at the time I wrote this.
