There is a path to C:\Program Files\gs\gs9.26\bin and to C:\Program Files\gs\gs9.26\bin.

Tracking the source of the Python exception, it seems that the code in __win32_finddll(): fails to find the Registry key.

Using Regedit, there is a key:

The statement QueryInfoKey(k1) returns (in _gsprint.py)

Any suggestions?

[vinayak-mehta]

Did you try the solutions mentioned in #184?

[rafiepstein]

Hello Vinayak,
I am not sure what you mean by "solution mentioned"...
As far as I could tell, no solution relevant to Windows environment is mentioned.
Ghoscript is installed as per the test suggested. PATH is setup correctly.
The problem seems to be in _gsprint.py,
line: for num in range(0, QueryInfoKey(k1)[0]):
as QueryInfoKey(k1)
(0, 0, 131955739057984515L)
thus range(0, QueryInfoKey(k1)[0]) is empty, and it doesn not find the dll.

Any suggestions?

[tal-yifat]

I have the same issue with the standalone version of Ghostscript (install version is not allowed due to the IT policy in my company). I had set the bin and lib directories of the Ghostscript (standalone) in PATH but Camelot is still trying to find the Ghostscript from the Windows registry.

[pantuts]

In macos brew install ghostscript

[tal-yifat]

In my case, Ghostscript is successfully installed. Shouldn't this be a bug?

[KAIXIE]

Ghostscript is successfully installed. Shouldn't this be a bug? yes it is a bug!!!!!

[vinayak-mehta]

I'll look into this over the weekend.

[wangxiangtao]

exact same issue as well. I have the same issue with the standalone version of Ghostscript (install version is not allowed due to the IT policy in my company). I had set the bin and lib directories of the Ghostscript (standalone) in PATH but Camelot is still trying to find the Ghostscript from the Windows registry.

[vinayak-mehta]

I currently don't have a Windows machine to reproduce this, let me install it on my current laptop. I believe we should just try to get rid of ghostscript with #96.

[GuillaumeDesforges]

Same issue here

[marcoloew333]

Same for me. Even if i install ghostscript and python3-ghostscript via pip.
macOS with PyCharm. Both latest versions.

I have the same issue. Although I've tried other install method to install ghost script, it still does not work...

[jtlz2]

macOS - brew install ghostscript - still get this error

[lswh]

Hi this error also exists for me.

[lswh]

I was investigating this code earlier and I noticed for my macOS implementation that it's having some issue with the conditional of libgs.so file which produces the runtime error. I tried working on both virtualenv and conda but I also suspect that the find_library cdll is not working in it somewhere. It does not detect the GhostScript even when I installed from source and did a make so compiled install because that file extension for MacOS is a different one from shared object on Linux. I presume this bug does not happen on Ubuntu/Linux and can only be observed in Windows and MacOS. I will try on a Linux machine and see if I am able to detect the same bug.

[slamer59]

Some hack:

Looking at sources:

camelot/camelot/ext/ghostscript/_gsprint.py

Line 223 in 9137df2

k1 = OpenKey(HKEY_LOCAL_MACHINE, "Software\\%s" % key_name)

My guess is that downloading : https://www.ghostscript.com/download/gsdnld.html
install some HKEY_LOCAL_MACHINE aka GS_DLL which solved the problem.

For ones who cannot add HKEY_LOCAL_MACHINE, add it to HKEY_CURRENT_USER\Software\key_name\GS_DLL\GS_DLL
GS_DLL is a REG_SZ containing dll path.

Choose key_name in "AFPL Ghostscript", "Aladdin Ghostscript", "GNU Ghostscript", "GPL Ghostscript",

Also import HKEY_CURRENT_USER here

camelot/camelot/ext/ghostscript/_gsprint.py

Line 192 in 9137df2

from _winreg import (

and here:

camelot/camelot/ext/ghostscript/_gsprint.py

MacOS, had the same error after running brew install ghostscript

Running brew link --overwrite ghostscript solved it.

[goutam-ghosh]

"errorMessage": "Please make sure that Ghostscript is installed",
"errorType": "RuntimeError"

getting this error while run the code using lambda function aws. Already camelot and ghostscript added as a dependency. I need to resolve as soon as possible. Please help.

my code is :
import camelot

def pdfToJson(event=None,context=None):
tables = camelot.read_pdf("./week-1-2019-20.pdf")
tables[0].df.to_json("./sample.json")

Note:Locally it is working properly.

#serverless #awslambda #python #camelot #ghostscript

[goutam-ghosh]

And more thing how to add ghostscript dependencies for lambda function python?

[pavankumarg1729]

Had the same Issue on Windows. I just installed Ghostscript installer from this Website: https://www.ghostscript.com/download/gsdnld.html My Code is now having no issues.

This resolved my issue too

[Cazforshort]

Same issue. Is there a way I can fix this with out modifying the code? The solutions above don't work if you are dependent on a requirements.in file for containerizing.

[thuynguyetquynh]

Same issue. I tried: "brew install ghostscript" and it said that my ghostscript was installed but not linked, so I fixed with:

sudo chown -R whoami /usr/local/share/doc/ghostscript/9.54.0
brew link --overwrite ghostscript

Worked perfectly with my MacOs

[kailichou]

I would recommend to install GhostScript via Chocolatey for Windows OS.

• Python: 3.8.9
• OS: Windows 10 Professional

I had this same problem. If you happen to have choco installed in your system.
choco install GhostScript -y

[vinayak-mehta]

Can you try installing the latest version with pip install "camelot-py[base]==0.10.1" and then trying out the poppler image conversion backend? Here's a snippet:

import camelot
tables = camelot.read_pdf("https://camelot-py.readthedocs.io/en/master/_static/pdf/foo.pdf", backend="poppler")
tables[0]
# <Table shape=(7, 7)>

More info in the docs here: https://camelot-py.readthedocs.io/en/master/user/advanced.html#use-alternate-image-conversion-backends

Please report issues here: https://github.com/camelot-dev/camelot/issues

[vinayak-mehta]

@rafiepstein Please close this issue If your problem is solved.

[garry8888]

If it is Windows 10 OS, add direction to the Ghostscript into the environment-variables system-paths (PATH):
C:\Program Files\gs\gs9.54.0\bin
After that restart your PC and try to run your code.
It have solved the proplem in my case.

[lenomosh]

I also had the same issue in Ubuntu. I had to run apt remove ghostscript && apt autoremove -y && apt install ghostscript && reboot

[siddhpant]

I also had the same issue in Ubuntu. I had to run apt remove ghostscript && apt autoremove -y && apt install ghostscript && reboot

Yes, but it is just reinstalling and a useless reboot. Problem lies somewhere else.

When I copy gs and all the related binaries (I cache them in a workflow) to the appropriate paths, read_pdf fails. But when I install with apt, it works. Maybe this might provide a clue?

[simonhuwiler]

Any updates on this? I have the same problem on my Mac M1 Big Sur.

Tried:

• install it with brew
• brew link --overwrite ghostscript (successfull)
• Installed it from pkg
• Add the path to every environment path I know
  Nothing works.

This finds the library 👇

import distutils.spawn
distutils.spawn.find_executable("gs")

This not 👇

from ctypes.util import find_library
find_library("gs")

The link /usr/local/bin/ exists and points to the right file.
gs in the terminal works fine as well.

[simonhuwiler]

//Edit//

It finally runs. I did this:

Install Ghostscript:

brew install ghostscript

Create System links (change version and path based on your system)

sudo ln -s /opt/homebrew/Cellar/ghostscript/9.55.0/lib/libgs.dylib.9.55 /usr/local/lib/libgs.9.dylib
sudo ln -s /opt/homebrew/Cellar/ghostscript/9.55.0/lib/libgs.dylib.9.55 /usr/local/lib/libgs.dylib
sudo ln -s /opt/homebrew/Cellar/ghostscript/9.55.0/lib/libgs.dylib.9.55 /usr/local/lib/libgs.dylib.9.55

Then checkout camelot version from github:

git clone [email protected]:camelot-dev/camelot.git

Open github folder in terminal and switch branch:

git checkout v0.7.3

Replace ctypes with distutils based on this pull-requests:

• open file camelot/ext/ghostscript/_gsprint.py
• add import distutils.spawn where other packages are imported
• replace libgs = ctypes.util.find_library("gs") with libgs = distutils.spawn.find_executable("gs")

Then create your virtual environment or install it globally:

• Navigate in your terminal to the camelot folder
• pip install -r requirements.txt
• python setup.py install

When everything run smoothly, try to use camelot. For me, I got an error like /usr/local/lib/libgs.dylib: mach-o, but wrong architecture. Then I had do make sure i installed a 64bit python version, create a virtual env based on this version and do all the things above again.

[siddhpant]

Instead of all that, you could install v0.10.x on <= Python 3.9.x, which removes dependency on ghostscript by adding a poppler backend (which in turn doesn't depend on system packages but rather on another Python library, I guess).

[michaeljcollinsuk]

In case this helps anyone, I was encountering this on Mac M1 running mac OS Big Sur. I had installed ghostscript with brew install ghostscript and installed camelot with pip. The Ghostscript check specified in the installation docs was failing.

I was able to resolve by adding export DYLD_LIBRARY_PATH="/opt/homebrew/lib" to my .zshrc, after which the above ghostscript check succeeded, and I was able to use camelot.read_pdf("foo.pdf") successfully

[saveyak]

This is how I solved for this problem on a Windows computer:

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 -> restarted computer
I 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.

And I heard that this solution works on a Mac: https://jsoma.github.io/m1-install-fixes/python/ghostscript/

[CharlesWit]

On a M1 Mac with macOS Monterey, after brew install ghostscript, creating the right system links passed the find_library('gs') check :

from ctypes.util import find_library 
find_library('gs')
# '/usr/local/lib/libgs.dylib'

and camelot.read_pdf() worked.
It's part of the solution given above, and it's listed at the link shown in the last comment.

@simonhuwiler Create System links (change version and path based on your system)

sudo ln -s /opt/homebrew/Cellar/ghostscript/9.55.0/lib/libgs.dylib.9.55 /usr/local/lib/libgs.9.dylib
sudo ln -s /opt/homebrew/Cellar/ghostscript/9.55.0/lib/libgs.dylib.9.55 /usr/local/lib/libgs.dylib
sudo ln -s /opt/homebrew/Cellar/ghostscript/9.55.0/lib/libgs.dylib.9.55 /usr/local/lib/libgs.dylib.9.55

@saveyak And I heard that this solution works on a Mac: https://jsoma.github.io/m1-install-fixes/python/ghostscript/

[sowec]

fwiw, the following worked for me while using pipenv on MacOS.

Install dependencies from the command-line:

brew install python-tk ghostscript tcl-tk

Add packages to PipFile, including, e.g., matplotlib "extra":

[packages]
camelot-py = {version="*", extras=["base", "plot"]}
opencv-python = "*" # for camelot-py
ghostscript = "*" # for camelot-py

Use pipenv shell to run camelot CLI:

pipenv shell
(dir) camelot -f json -o out.json lattice in.pdf

Perhaps due to pipenv, it was not enough to install ghostscript, et al in the system. I needed the python packages for opencv-python and ghostscript. The best way to manage system library dependencies with pipenv is unclear.

Good luck -

[starscream2290]

you may use this link to properly install ghostscript on win10.. works fine with me now.

And I heard that this solution works on a Mac: https://jsoma.github.io/m1-install-fixes/python/ghostscript/

Hey, that's mine! And I have a new improved suggestion to solve this for OS X! Three little baby lines of code to solve all your problems:

brew install ghostscript # You probably did this already

mkdir -p ~/lib
ln -s "$(brew --prefix gs)/lib/libgs.dylib" ~/lib

I put together a long writeup about why it works, but the basics:

• Problem: Newer versions of OS X ship with SIP (System Integrity Protection) which blocks most attempts to use DYLD_* to set library paths. You can disable it, but eh.

• Solution: It turns out that Python looks in your /Users/username/lib folder for libraries before anywhere else, so all we need to do is drop a symlink in ~/lib to the homebrew ghostscript and we're good to go!

I had the same problem. When running camelot.read_pdf I faced the aforementioned error. And running ctypes.util.find_library("gs") returned no results (which means the gs library could not be found by Python).

I am using MacOS. Following solutions didn't work for me:

• Adding the directory of libgs.dylib to the PATH environment variable
• Installing ghostscript with brew or with pip
• homebrew link --overwrite ghostscript

I haven't tried to install it with conda since I'm not using conda anyway.

I had to follow the steps below to solve the issue:

• First download ghostscript from https://ghostscript.com/releases/
• Unzip the file
• cd to unzipped directory and do following:

    ./configure
    make
   make install (might need root privileges) 

• Then the file libgs.dylib should be found under /opt/homebrew/lib/libgs.dylib (otherwise find this file's path)
• You need to link this file to /usr/local/lib using the following command (if the directory /usr/local/lib does not exist then create it):
  ln -s /opt/homebrew/lib/libgs.dylib /usr/local/lib/libgs.dylib

After following these steps I could successfully use camelot.

On M2 Mac this worked -

1. brew install ghostscript tcl-tk
2. pip install camelot-py[base]
3. pip install 'PyPDF2<3.0'

For Co-Lab
! apt install python3-tk ghostscript

Hey all!

We try to build a maintained fork at pypdf_table_extraction.

On m1 mac the following worked for me

sudo mkdir -p /usr/local/lib
sudo ln -s /opt/homebrew/Cellar/ghostscript/10.04.0/lib/libgs.10.dylib /usr/local/lib/libgs.10.dylib
sudo ln -s /opt/homebrew/Cellar/ghostscript/10.04.0/lib/libgs.dylib /usr/local/lib/libgs.dylib
sudo ln -s /opt/homebrew/Cellar/ghostscript/10.04.0/lib/libgs.dylib.10.04 /usr/local/lib/libgs.dylib.10.04
