I'm a newbie to Python, While learning imgkit (PI module) I got this error which was not expected for a simple code. Below is the code
import imgkit
imgkit.from_url('https://www.google.co.in/','fs.jpg')
and the error which I got is
Traceback (most recent call last):
File "G:\python\lib\site-packages\imgkit-0.1.8-py3.6.egg\imgkit\config.py", line 30, in __init__

During handling of the above exception, another exception occurred:

OSError: No wkhtmltoimage executable found: "b''"
If this file exists please check that this process can read it. Otherwise please install wkhtmltopdf - http://wkhtmltopdf.org
Could anyone tell me what mistake I have done.
you need to these lines after installing wkhtmltopdf on your windows system:
path_wkthmltoimage = r'C:\Program Files\wkhtmltopdf\bin\wkhtmltoimage.exe'
config = imgkit.config(wkhtmltoimage=path_wkthmltoimage)
imgkit.from_file('table.html', 'table.jpg',config=config)
try: brew install caskroom/cask/wkhtmltopdf
It looks like you need to install wkhtmltopdf. To do so, run pip install wkhtmltopdf

Just trying the quickstart described here:

I've copied the small code sample and created the template sheet as described. When I run report.py, I get the following:

This is essentially out of the box so I can't see that I've done anything wrong. I'm running on Ubuntu 20.04.5 LTS. Python is 3.8.10. I have the follwing dependencies:
numpy==1.23.4
pandas==1.5.1
python-dateutil==2.8.2
pytz==2022.5
six==1.16.0
xlwings==0.28.2
Any suggestions? Thanks.
Traditionally, xlwings only worked on Windows or macOS with an actual installation of Microsoft Excel. More recently (in 2022) it added Linux support for xlwings Server and xlwings File Reader, but xlwings Reports still has to be run in connection with Excel, i.e., runs on Windows and macOS only. While the installation instructions mention this, I'll try to improve the docs to mark the requirements on the respective pages.
I installed OpenALPR itself fine and I was able to run it in terminal to get this result:
C:\Users\zebsu>"C:\\OpenALPR\\Agent\\bin\\alpr.exe" "C:\\plate.jpg"
plate0: 3 results

- P265BYV confidence: 81.1941 pattern_match: 0
- P65BYV confidence: 81.1336 pattern_match: 0
However, I then followed the instructions found on PyPI (https://pypi.org/project/openalpr/#description) to install the openalpr python bindings with pip install openalpr. But when I run the following code that they suggest with python 3.8.6 x64:
import json
from openalpr import Alpr
alpr = Alpr("us", "C:/OpenALPR/Agent/etc/openalpr/openalpr.conf", "C:/OpenALPR/Agent/usr/share/openalpr/configruntime_data")
if not alpr.is_loaded():
print("Error loading OpenALPR")
sys.exit(1)
results = alpr.recognize_file("C:/image.jpg")
print(json.dumps(results, indent=4))
alpr.unload()
I get the following error:

I've scoured all the internet forums looking for answers however most of the submissions are from years back before the openalpr bindings could be installed with pip and had to be installed from github. Does anyone have any advice?
I ended up finding the solution from the answer to a question on another thread with a similar error but with a different library: FileNotFoundError: Could not find module 'libvlc.dll'. The issue was that the program had no way to find the dll files it needed so the directory where the dll files are needs to be added to the os in the python code. For me this meant adding these lines to the top of my code:
import os
os.add_dll_directory("C:/OpenALPR/Agent/bin")
This change meant that the code ran exactly as it was supposed to.
Running into issue with keyring:
RuntimeError: Unable to initialize SecretService: Environment variable DBUS_SESSION_BUS_ADDRESS is unset
SecretService is installed.
OS is RHEL
Running:
python -c "import keyring.backends.SecretService as SS; SS.Keyring.priority"
gives the following error:

How can I fix this?
Missing dependency: dbus-python
Try doing this:
dbus-run-session -- python -c "import keyring.backends.SecretService as SS; SS.Keyring.priority"
SecretService (Gnome Keyring) needs a DBUS session. If you're running on a headless server, you'll need to run the app that needs access to keyring inside a dbus session (as shown above).
Adding this to my .zshrc was the only thing that ended up working for me:
export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring
I created a python script (packaged as post-commit.exe) to run as an SVN post commit hook. Yes, the hook runs, but this is the line I am having problems with:
App = win32com.client.GetActiveObject("EA.App")
This issue does not happen on Windows 7, but is now happening on Windows Server 2012 R2 with the same installs:
TortoiseSVN-1.9.0.26652-x64-svn-1.9.0.msi
pywin32-220.win-amd64-py3.3.exe
python-3.3.0.amd64.msi
I used pip to explicitly install pypiwin32, but I can't tell if it actually worked or not (or if it matters). It says it's installed, but at the end of the install it gives me the following even tho I ran as admin:
PermissionError: [Errno 13] Permission denied: 'c:\\python33\\Lib\\site-packages\\pythoncom.py'
When I open this .exe it runs fine and works as expected, but when it is kicked off by the actual SVN commit, SVNTortoise gives me the error message below. I had problems with SVN deleting PATH for other lines of code, so I have also tried the full path to where EA.exe lives. I ran wmic get ProcessID and also tried what that gave me... but these do not work either:
App = win32com.client.GetActiveObject(r"C:\Program Files (x86)\Sparx Systems\EA\EA.App")
App = win32com.client.GetActiveObject(r"C:\PROGRA~2\SPARXS~1\EA\EA.App")
Any help would be greatly appreciated. I have spent a lot of time googling and searching stackoverflow for answers, but can't find anything for this specific problem. Thanks!!

how do I install spynner? Thanks
i recently got the same error as you are , and i fix it without using the pip command
download the spynner zip file and unzip to the C:\Anaconda\Lib\site-packages
here is the link:
https://pypi.python.org/pypi/spynner
download the autopy file and install the windows installer
https://pypi.python.org/pypi/autopy/0.51
