I am trying to extract tabular data from pdf using camelot and I am getting the following error.
Code:
tables = camelot.read_pdf(file_name)
Error:
GhostscriptNotFound: Please make sure that Ghostscript is installed and available on the PATH environment variable
I have already installed Ghostscript and I have it available on the PATH environment variable.
Please find below version details:
Windows-10-10.0.17134-SP0
Python 3.6.5 |Anaconda, Inc.| (default, Mar 29 2018, 13:32:41) [MSC v.1900 64 bit (AMD64)]
NumPy 1.14.3
openCV 3.4.3
Camelot 0.3.2
Please help resolve this issue.
Adding both the "bin" and "lib" paths for Ghostscript to the PATH worked for me:
C:\Program Files\gs\gs9.26\bin
C:\Program Files\gs\gs9.26\lib
I unistalled the 64bit and
Install the 32bit version
Add the following two paths on Windows Environment Variables:
C:\Program Files(x86)\gs\gs9.26\bin
C:\Program Files(x86)\gs\gs9.26\lib
and now it works
Download Ghostscript from here https://www.ghostscript.com/download/gsdnld.html and add it to the path if required
For me using brew link -f --overwrite ghostscript solved the issue.
I would recommend checking the suggested solutions on https://github.com/atlanhq/camelot/issues/282. That's where I also found my fix.
Tried all the solutions. The only option that works is to use 32 bit ghostscript.
I had the same problem. I solved it by uninstalling the 64 bit version and installing the 32 bit version.
I realized that. If you are using the Python 64bit you need install ghostcript64 bit, else 32 bit.
Also set path for 64bit:
C:\Program Files\gs\gs9.26\bin
C:\Program Files\gs\gs9.26\lib
or for below for 32bit
C:\Program Files(x86)\gs\gs9.26\bin
C:\Program Files(x86)\gs\gs9.26\lib
Here is my solution (Windows OS (11, 64 BIT)):
Download and install the desired ghost version you wish (32,64 - does not matter)
Using "dir /x" command, get the short version of the path of your installation (c:\progra~1\blahbla...). My location (I love altering the default suggestion) is "C:\Program Files\gs\GPLGhostScript" and the short name is "c:\progra~1\gs\GPLGhostScript"
Add this to the path together with \bin. In my case "c:\progra~1\gs\GPLGhostScript\bin" (no need for lib path as suggested by others)
Restart your PC
Test your installation of GhostScript according to this link.
Good luck :)
This worked for me:
C:\Program Files\gs\gs9.55.0\bin
Just find the path location, copy it, and paste it into user and system variables Path (Environment variables).
I solved this problem.
I downloaded Ghostscript.
Then installed it at C:/programfiles.
Added set path: C:\Program Files\gs\gs9.26\bin + C:\Program Files\gs\gs9.26\lib
Restarted my computer.
After these steps, it worked.
A very simple way is to install Ghostscript from the official website.
Then give the location while set-up the library in the Anaconda script folder. Wait for 10 minutes after closing the Python platforms.
I was facing same issue for 2 days. I found solution at below link.
for windows 10, I used below method
in "search the web and windows" write "under edit environment variable for your account in control panel."
edit path for lib and bin library of Ghostscript here. add ; to separate the path at end also.
set path in environment variable
For more info used below link. It worked fine for me.
https://github.com/atlanhq/camelot/issues/465#issuecomment-975976344
For me, uninstalling camelot and re-installing with
conda install -c conda-forge camelot-py instead of pip solved the problem (as ghostscript is also re-installed)
In case you are fed up with all the errors derived from the usage of Ghostscript and want to find a way to use Camelot without using Ghostscript, here is the fork of it which does not rely on it.
Camelot fork without Ghostscript
Installation guide is similar, but this time from the github repo itself.
First, install these dependencies:
!pip install pdf2image
!pip install python-dateutil
!apt-get install poppler-utils
Then clone the repo
$ git clone https://www.github.com/h2oai/camelot
Finally, go to the repo directory and install camelot from there.
$ cd camelot
$ pip install ".[base]"
Import camelot and happily use it :)
This is how I solved for this error on a Windows computer, similar to what Alexander Garzo posted:
Went to File Explorer -> C drive -> Program Files -> gs -> gs9.55.0 -> shift-clicked on bin folder -> copied as path ("C:\Program Files\gs\gs9.55.0\bin")
Then went to environmental variables -> Path -> Edit -> New -> pasted above -> OK -> restarted computer.
I then ran the following code in Python:
import ctypes
from ctypes.util import find_library
find_library("".join(("gsdll", str(ctypes.sizeof(ctypes.c_voidp) * 8), ".dll")))
The output was "C:\Program Files\gs\gs9.55.0\bin\gsdll64.dll" which means the solution worked. I was then able to install and use Camelot with no problems.
I was getting this Error (OSError: Ghostscript is not installed. You can install it using the instructions here: https://camelot-py.readthedocs.io/en/master/user/install-deps.html)
I tried everything mentioned here and also in Github.
but after installing Ghostscript from here and then adding to the PATH.
I keep trying methods to solve it.
BUT the solution is to just Restart your computer and everything Works.
so Restart is Must.

I have followed all the steps shared in all stackoverflow and other questions out there to install gettext for windows (10), but still, I get the error: "Can't find msguniq, make sure you have gettext tools installed" when using internationalization in django. I have tried to download the files directly and added them to the PATH, and even an installer that had already compiled everything and added to the path automatically, but it still doesn't work, and I don't know what else to do... Help please!
Thank you for your time.
I had the same problem. I tried various solutions to no avail. Finally, I downloaded the binaries from https://mlocati.github.io/articles/gettext-iconv-windows.html
and it worked.
Not sure what problem you face but below command worked for me
pip install python-gettext
In windows you just need to download :
gettext-tools-xx.zip
gettext-runtime-xx.zip
from here: enter link description here
and then you need to unzip them and copy all in bin folder of both files into C:\Program Files\gettext-utils\bin and then you need to go to control panel-> system -> advanced -> environment variables and add this path:C:\Program Files\gettext-utils\bin to path variables. Note:
xx is the version you want to download if you download version 18 you will get an error that some dll file is missing, I suggest to download version 17
this folder: gettext-utils\bin does not exist and you need to create it
restart your pc before you use gettext
When running python26 under windows OS (64bits).....
I have got errors like:

ImportError: DLL load failed: The specified module could not be found.
I have done the msi installation for python26

After I copy pywintypes26.dll and pythoncom26.dll from C:\Python26\Lib\site-packages\pywin32_system32 to C:\Python26\Lib\site-packages\win32 -> Solve the problem!
I also hit a problem importing win32api.
The post-install script for pywin32 failed, which should copy pythoncom26.dll, pythoncomloader26.dll, and pywintypes26.dll, among other things. I ran it by hand and my installation was fixed.
python scripts\pywin32_postinstall.py -install
I had a similar problem when installing under 64 bit Python 3.4.2. I ran the install executable pywin32‑219.win‑amd64‑py3.4.exe from http://www.lfd.uci.edu/~gohlke/pythonlibs/ .
On the site it states clearly:
"Python 3.4 users must manually run python.exe Scripts\pywin32_postinstall.py -install from an elevated command prompt."
which I did not do first time round; I installed from a normal prompt getting the following feedback:
c:\python34>python.exe Scripts\pywin32_postinstall.py -install

And now my code runs happily (as far as this matter is concerned... sigh, so much other stuff to do).
Run the installer as Administrator and it works:

Choose "Run as Administrator"
As suggested above the post install script is not run, this issue can be seen when installing from a wheel (As I encountered)
python scripts\pywin32_postinstall.py -install
If find you have this issue when installing via wheels, then installing it from here can solve the above issue.
https://pypi.python.org/pypi/pypiwin32
There appears to be a bug in the installer. The recommended workaround in the ticket is the same one as proposed by Dave Bremer.
I could fix this situation by removing all installed Python3.4 versions (had forgotten to uninstall 3.4.1 before installing 3.4.2), deleting C:\Python34 and after installing Python 3.4.2 pywin32-219.win32-py34.exe could be installed and called without problems.
So, copying around DLLs should NOT be necessary!
I always install the Active State Python distro which installs the win32 packages for you and gets it right.
If the above didn't fix the problem, you're still missing the msvcr100.dll file. It's either in your \System32\ folder, or more likely in your c:\PythonXX\Lib\site-packages\win32\ folder.
That fixed it for me after hours of search to no avail, even though it looks like the import still isn't resolved as it should be (PyCharm still gives me the squiggly underline), but it works.
First I was using pip to install pywin32 in anaconda environment, that's why no matter what I did it was failing. After trial and error, I figured out that
conda install pywin32
is the right way to install pywin32 in the anaconda package manager.
I don't know whether it's too late or not to answer this question. I also hit this problem, and I tried every method above, but neither of them worked.
Finally, I found the reason. When we install pywin32, we must choose the one that fits python's version(2.6， 2.7， 3.3， etc) and python's bit number(x64 or x86). Notice, it must fit python's bit number, not PC's bit number. If you install x86 python in a x64 PC, you have to install a pywin32 with x86.
In my case i had to copy pywintypes26.dll and pythoncom26.dll files into C:\Windows\System32 folder to work it properly in jupyter notebook.
I am using windows 10 OS with multiple python versions
I have a situation very much like the one at Error "ImportError: DLL load failed: %1 is not a valid Win32 application", but the answer there isn't working for me.
My Python code says:
import cv2
But that line throws the error shown in the title of this question.
I have OpenCV installed in C:\lib\opencv on this 64-bit machine. I'm using 64-bit Python.
My PYTHONPATH variable: PYTHONPATH=C:\lib\opencv\build\python\2.7. This folder contains cv2.pyd and that's all.
My PATH variable: Path=%OPENCV_DIR%\bin;... This folder contains 39 DLL files such as opencv_core246d.dll.
OPENCV_DIR has this value: OPENCV_DIR=C:\lib\opencv\build\x64\vc11.
The solution at Error "ImportError: DLL load failed: %1 is not a valid Win32 application" says to add "the new opencv binaries path (C:\opencv\build\bin\Release) to the Windows PATH environment variable". But as shown above, I already have the OpenCV binaries folder (C:\lib\opencv\build\x64\vc11\bin) in my PATH. And my OpenCV installation doesn't have any Release folders (except for an empty one under build/java).
What's going wrong? Can I tell Python to verbosely trace the loading process? Exactly what DLL files is it looking for?
I noticed that, according to http://www.dependencywalker.com/, the cv2.pyd in C:\lib\opencv\build\python\2.7 is 32-bit, whereas the machine and the Python I'm running are 64-bit. Could that be the problem? And if so, where can I find a 64-bit version of cv2.pyd?
Unofficial Windows Binaries for Python Extension Packages
You can find any Python libraries from here.
Please check if the Python version you are using is also 64 bit. If not then that could be the issue. You would be using a 32-bit Python version and would have installed a 64 bit binaries for the OpenCV library.
Wow, I found yet another case for this problem. None of the above worked. Eventually I used python's ability to introspect what was being loaded. For Python 2.7, this means:
import imp
imp.find_module("cv2")
This turned up a completely unexpected "cv2.pyd" file in an Anaconda DLL directory that wasn't touched by multiple uninstall/install attempts. Python was looking there first and not finding my good installation. I deleted that cv2.pyd file and tried imp.find_module("cv2") again and python immediately found the right file and cv2 started working.
So if none of the other solutions work for you, make sure you use Python introspection to see what file Python is trying to load.
In my case, I have 64-bit Python, and it was lxml that was the wrong version--I should have been using the x64 version of that as well. I solved this by downloading the 64-bit version of lxml here:
https://pypi.python.org/pypi/lxml/3.4.1
lxml-3.4.1.win-amd64-py2.7.exe
This was the simplest answer to a frustrating issue.
I just had this problem. It turns out it was just because I was using an 64-bit version of the OpenCV file. I tried the x86 and it worked.
I had the same problem. Here's what I did:
I downloaded the pywin32 wheel file from here, then
I uninstalled the pywin32 module. To uninstall, execute the following command in a command prompt.
pip uninstall pywin32
Then, I reinstalled pywin32. To install it, open the command prompt in the same directory where the pywin32 wheel file lies. Then execute the following command.
pip install <Name of the wheel file with extension>
Wheel file will be like: piwin32-XXX-cpXX-none-win32.whl
It solves the problem for me.
I copied cv2.pyd file from /opencv/build/python/2.7/x86 folder instead of from /x64 folder to C:/Python27/Lib/site-packeges. I followed rest of the instructions provided here.
Added by someone else, not verified: I also copy file cv2.pyd to folder C:/Python27/Lib/site-packages/cv2. It works.
For me the problem was that I was using different versions of Python in the same Eclipse project. My setup was not consistent with the Project Properties and the Run Configuration Python versions.
In menu Project → Properties → PyDev, I had the Interpreter set to Python 2.7.11.
In Run Configurations → Interpreter, I was using the Default Interpreter. Changing it to Python 2.7.11 fixed the problem.
If your build system (CMake in my case) copies the file from <name>.dll to <name>.pyd, you will get this error if the original file wasn't actually a DLL file. In my case, building shared libraries got switched off, so the underlying file was actually a *.lib.
I discovered this error by loading the pyd file in Dependency Walker and finding that it wasn't valid.
Update NumPy.
pip install numpy --upgrade
It works for me!
This one worked for me:
pip install -- pywin32==227
I faced the same issue when I uninstalled and reinstalled a different version of 2.7.x of Python on my system using a 32-bit Windows Installer. I got the same error on most of my import statements.
I uninstalled the newly installed Python, downloaded a 64-bit Windows installer, reinstalled Python again, and it worked.
So I had problems installing vtk under Windows (as I use Python 3.7, there isn't any binary available so far. Just for older Python versions pip install vtk is not working)
I did wrote Python in my cmd:
Python 3.7.3 on win32
So I now know I have Python 3.7.3 running on a 32 bit.
I then downloaded the correct wheel at VTK‑8.2.0‑cp37‑cp37m‑win32.whl
Next I installed that wheel:
pip install VTK-8.2.0-cp37-cp37m-win32.whl
Then I tested it and it worked:
python
import vtk
I experienced the same problem while trying to write code concerning speech-to-text.
The solution was very simple. Uninstall the previous pywin32 using the pip method:
pip uninstall pywin32
The above will remove the existing one which is by default for 32 bit computers. And install it again using
pip install pywin32
This will install the one for the 64 bit computer which you are using.

You can install opencv from official or unofficial sites.
Refer to this question and this issue if you are using Anaconda.
It has a very simple solution.
After installing opencv
place
cv2.pyd from C:\opencv\build\python\2.7\ **x64** to C:\Python27\Lib\site-packages
instead of, place cv2.pyd from C:\opencv\build\python\2.7\ **x86** to C:\Python27\Lib\site-packages
I got this error when trying to import MySQLdb.
What worked for me was to uninstall Python and then reinstall it.
I got the error after installing npm (https://www.npmjs.com/get-npm). One thing it did was install Python even though I already had it.
First I copied cv2.pyd from /opencv/build/python/2.7/x86 to C:/Python27/Lib/site-packeges. The error was
"RuntimeError: module compiled against API version 9 but this version of numpy is 7"
Then I installed numpy-1.8.0-win32-superpack-python2.7.exe and OpenCV works fine.
>>> import cv2
>>> print cv2.__version__
2.4.13
Please make sure that you have installed a Python 2.7.12 or below version. Otherwise you will definitely get this error.
Make sure the Oracle client is 64 bit installed if the OS is 64 bit.
Make sure the Microsoft Visual C++ compiler for Python 2.7 is 64 for bit for a 64 bit OS or 32 bit for 32 bit.
Note: If your OS is 64 bit, install all packages of 64 bit or if the OS is 32 bit, install the 32-bit package.
This has worked for me. I have tried different methods, but this was my best solution.
Open a command prompt and type the following;
pip install opencv-python
(Make sure your Internet connection is on.)
After that, try importing it again.
It could also be that your Anaconda version is 32 bit when it should be 64 bit.
If you are using pycharm I go to settings -> python interpretation and click the + button and search for the name on the list of python packages there

I found the solution. Maybe you can try to use the cmd window rather than the Anaconda prompt window to start your first Scrapy test.
I'm using 64 bit Ubuntu 12.04. When i'm installed wkhtmltopdf package. When I print web kit report it's show following error.
Wkhtmltopdf library path is not set
Please install executable on your system (sudo apt-get install wkhtmltopdf) or download it from here: http://code.google.com/p/wkhtmltopdf/downloads/list and set the path in the ir.config_parameter with the webkit_path key.Minimal version is 0.9.9
Please Help me to configure the webkit package
I had the same issue, i solved mine using this one
http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-amd64.tar.bz2
everything else is same as #Adrian Merrall explained.
Easiest is to just head to http://wkhtmltopdf.org/ and grab the 64 bit download rather than use the deb package (although that should work too).
Unpack it somewhere and ensure the same user running OpenERP has execute rights on it.
Test from bash with wkhtmltopdf --version
In OpenERP - Settings -> Parameters -> System Parameters -> webkit_path
Set to the full path, e.g.
/usr/local/bin/wkhtmltopdf
and you should be in business
