PdfFileReader is deprecated and was removed in PyPDF2 3.0.0 #339

szeswee · 2022-12-23T04:41:40Z

Describe the bug

Version 3.0.0 of PyPDF2 was just released today (23 Dec 2022), which includes a breaking change for removing PdfFileReader (see changelog). As a result, all new installs and usage of camelot-py will raise the following exception:

Traceback (most recent call last):
  File "test.py", line 9, in <module>
    camelot.read_pdf(PDF_FILE_PATH)
  File ".venv/py37/lib/python3.7/site-packages/camelot/io.py", line 117, in read_pdf

    raise DeprecationError(msg)
PyPDF2.errors.DeprecationError: PdfFileReader is deprecated and was removed in PyPDF2 3.0.0. Use PdfReader instead.

Steps to reproduce the bug

Create a new virtualenv
Install camelot-py:
```
pip install camelot-py[base]
```

Run the following code:

import camelot

# replace with a valid path on your local filesystem
PDF_FILE_PATH = "/path/to/file.pdf"

# raises an exception from PyPDF2
camelot.read_pdf(PDF_FILE_PATH)

Expected behavior

The code above should execute without any exceptions.

Environment

OS: macOS 12.3.1
Python version: 3.7
Numpy version: 1.24.0
OpenCV version: 4.6.0.66
Ghostscript version: 0.7
Camelot version: 0.10.1

As a workaround, I've added this line in my requirement.txt for the time being:

PyPDF2~=2.0

KshitizPandya · 2022-12-27T13:48:00Z

Hey @szeswee,

Gone with the steps, created a virtual environment through terminal, and executed the script in the IDE, as well as in colab, giving the same error.

saidakyuz · 2022-12-28T11:46:01Z

Hey @szeswee I also tried on both platforms(see screenshots) like @KshitizPandya and have the issue still. Does it work for you? Can you explain it more in detail?

MartinThoma · 2022-12-28T23:26:10Z

As a side-note: PyPDF2 should now be considered deprecated. We will continue development at pypdf, see History of pypdf

owen800q · 2022-12-29T10:57:38Z

We are hitting this issue now, any workaround fix?

anakin87 · 2022-12-29T11:18:38Z

@vinayak-mehta if you want, I'm available to submit a PR to fix this issue.

alprnyldz · 2022-12-29T12:34:41Z

As a workaround, I've added this line in my requirement.txt for the time being:
PyPDF2~=2.0

Thank you for the workaround fix

KshitizPandya · 2022-12-29T13:44:19Z

Hey @saidakyuz , I did a bit of work around and now my camelot is working fine. Am mentioning the steps below if you want to refer.

Set anaconda env (preferably use python 3.7)
Install camelot -
pip install camelot-py[base]
It will itself download the pyPDF2 version 3.0.0, so you need to extensively change the version -
pip install 'PyPDF2<3.0'
I used pyCharm to work with my script so I set the environment from settings and then it worked fine.

Environment packages:
camelot-py 0.10.1
ghostscript 0.7
pypdf2 2.0.0

Note: It might sometimes create error showing ghostscript is not installed. You can explicitly install it from: https://ghostscript.com/releases/gsdnld.html
and then set it computer's environment variable to bypass any issues and restart.

Then the issue should be resolved.

OUTPUT:

Hope it helps.

MartinThoma · 2022-12-29T14:00:15Z

@KshitizPandya Please replace pip install pyPDF2 == 2.0 by pip install 'PyPDF2<3.0'

KshitizPandya · 2022-12-29T14:03:22Z

@KshitizPandya Please replace pip install pyPDF2 == 2.0 by pip install 'PyPDF2<3.0'

Thanks for the correction @MartinThoma

dmitry-ra · 2022-12-29T16:03:23Z

Another possible way is to downgrade installed version of PyPDF2:

pip install --upgrade PyPDF2==2.12.1

Rhackleford · 2022-12-29T16:09:11Z

@vinayak-mehta if you want, I'm available to submit a PR to fix this issue.

Im so close to getting my program finished, when i run in pycharm the code runs fine when i run the exe i get the
""PyPDF2.errors.DeprecationError: PdfFileReader is deprecated and was removed in PyPDF2 3.0.0. Use PdfReader instead.[17036] Failed to execute script 'Werks' due to unhandled exception!""
error

the suggested workarounds arent working for me, probably because this is my first program.
i would LOVE a fix or a workaround that i can do..
please advise!

Rhackleford · 2022-12-29T16:24:26Z

pip install --upgrade PyPDF2==2.12.1

I tried this and also downgraded to PyPDF2.0, i get the same result, the deprecation error. I'm sure I'm missing something dumb.
i am running the camelot-py[cv] version of camelot, would that have anything to do with it?

MartinThoma · 2022-12-29T16:30:51Z

@RhacklefordGPT most likely you downgraded it in the wrong environment. So you have two places where PyPDF2 is installed. You need to ensure to downgrade it in the correct one.

For example, you might need pip3. Or you might need to load a virtual environment.

To verify, you can add the following before you import camelot:

import PyPDF2

print("PyPDF2==" + PyPDF2.__version__)

Looks like that did the trick.
my project is in a venv and I had been using the pycharm terminal to pip anything,
looks like before I was using venv I had installed it using CMD directly.
I'm still not clear on why if I use pyinstaller through Pycharm it tries to use things installed using cmd, I would think those are separated somehow, but really I do have a loose grasp of how this all works, could you recommend some further reading so I can avoid this? should I delete every installation of everything outside my venv?
ps thank you very much now I can bring a finished product into work and blow some minds with it!!! :)

import PyPDF2

print("PyPDF2==" + PyPDF2.version)

i have already do that but i get other 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
although it is installed already

Hey @au3m,
Doing just the installation sometimes might not help. Sometimes you might need to set the things in the computer's environment variables to access it easily.
So try setting "ghostscript" to your environment variables.

STEPS FOR REFERENCE:

copy the path where you have installed ghostscript.
If you are using windows - search for "Edit the system environment variable" .
above dialog should open. Click on the "environment variable" tab.
Under "system variables" section double click "path".
Click on the open space and paste the copied path of the ghostscript.
Click OK and for precautions restart your device.

After this your program should run fine without giving the ghostscript related error.

@KshitizPandya
Thanks bro it works now ☺️

AChnki · 2022-12-31T13:41:34Z

I think the problem is based on a missed migration considering the naming adjustments within PyPDF2/pypdf - see the following doc: https://pypdf2.readthedocs.io/en/stable/user/migration-1-to-2.html

Following the The Deprecation Process of PyPDF2/pypdf they are not longer tolerated.

I replaced the handlers.py-file with the file from the PR below and the cli is working again for me.

hey, I am getting this error on m2 mbp, would anyone know how to fix? I've verified gs is installed

Prathamesh-gunjal · 2023-03-08T10:01:57Z

Still getting this error please help!!

AayushSameerShah · 2023-05-25T05:32:21Z

If anyone trying to do this on colab then run the following steps:

!pip install ghostscript
!pip install camelot-py[cv]
!pip install excalibur-py
!apt install ghostscript python3-tk

And after that check if installed:

from ctypes.util import find_library

# It will display `libgs.so.9` if installed or will print `None` if not
print(find_library("gs"))

If still doesn't work:

!excalibur initdb
