Hi @nithinreddyy :wave:
Thanks for reporting this! There are a few things missing to identify where this comes from. Would you mind sending the full traceback please (there should be multiple other lines of error traces before the ones you posted)?
Also, could you run the environment collection script and post the result over here please? :pray:
wget https://raw.githubusercontent.com/mindee/doctr/main/scripts/collect_env.py
# For security purposes, please check the contents of collect_env.py before running it.
python collect_env.py
Cheers :v:

It's not even showing in the installed libraries list. Below is the image
Thanks for the traceback, it comes from weasyprint then :thinking: About your last message, I think I wasn't very clear: would you mind running this snippet:

python collect_env.py
and paste the exact result of here please? :pray:

Can you please mail me to nithinreddy1677@gmail.com? Here i think it'll take so much time. It'd be helpful.
Hi @nithinreddyy :wave:
Well it's better if we can solve your problem here since it may help others looking for a solution to that :sweat_smile:
It is indeed strange, it seems like you haven't installed docTR yet. Let's try to do this with the latest version:
pip install -e git+https://github.com/mindee/doctr.git#egg=python-doctr[tf]
or
pip install -e git+https://github.com/mindee/doctr.git#egg=python-doctr[tf]
Anyway, back to your problem, we need to get from weasyprint import HTML
to work on your system because this is the source of the problem. Perhaps the best way is to check their official installation steps for Windows: https://doc.courtbouillon.org/weasyprint/stable/first_steps.html
pip install -e git+https://github.com/mindee/doctr.git#egg=python-doctr[tf]
It's returning the same issue. Below is the image
Oh but then the problem was not on the import, but at the installation step for sure. Have you tried my suggestion of following installation instructions?

Yes, i tried installing weasyprint. It installed.
I ran 'python -m pip install weasyprint' this command, it worked well. Then i tried running 'python -m weasyprint --info', then it returned the error like pango...
I don't know from where it's the exact problem is.
Weasyprint is installed. Below is the image for your reference
According to your previous traceback, the problem definitely comes from weasyprint. You installed the lib, but apparently, the installation isn't working as it should (cf. pango error). Hard for me to help, we're mostly running Linux here and I haven't been able to reproduce your error :/
Perhaps the best thing to do is to open an issue on their repo https://github.com/Kozea/WeasyPrint ?

Ok
Let us know if you hear from them because I'm afraid we cannot do much over here :pray: This is the type of problem we cannot solve by modifying docTR, but we can inform users on how to get around it :+1:
Hi @nithinreddyy :wave:
Did you manage to get an answer to your problem? :)
Hi @nithinreddyy :wave:
Did you manage to get an answer to your problem? :)
No.
I managed to solve this issue by the following steps, this is for windows 10, python 3.9.1
Thanks for reporting that @rishabhshah13 :pray: @nithinreddyy this might be worth a try perhaps?

Will try and let you know.
Thanks for reporting that @rishabhshah13 🙏 @nithinreddyy this might be worth a try perhaps?
It's returning the same error.
@nithinreddyy Install different versions of GTK3 and check which on works for you
@nithinreddyy Install different versions of GTK3 and check which on works for you
Where can i get the different versions? Please let me know if you have any idea.
I managed to solve this issue by the following steps, this is for windows 10, python 3.9.1
- Install gtk3-runtime-3.24.14-2020-02-21-ts-win64.exe version (https://github.com/tschoonj/GTK-for-Windows-Runtime-Environment-Installer/releases/download/2020-02-21/gtk3-runtime-3.24.14-2020-02-21-ts-win64.exe)
- Download harfbuzz-4.0.1 (https://github.com/harfbuzz/harfbuzz/releases/download/4.0.1/harfbuzz-win64-4.0.1.zip)
- Copy all content from harbuzz and paste it to GTK3-Runtime Win64\bin
Download different version from here: https://github.com/tschoonj/GTK-for-Windows-Runtime-Environment-Installer/releases
and perform the 2 other steps
Checking in: @nithinreddyy did you manage to solve your problem? :)
Hi @nithinreddyy 👋 any updates ? :)
Hi @nithinreddyy 👋 any updates ? :)
No.
Hi @nithinreddyy 👋 any updates ? :)
No.
Still not working? Then could you please try to install doctr from main branch?

Yes, will try.
Thanks ❤️
Should work now (with main branch) otherwise feel free to reopen :)
@felixdittrich92 mind adding a reference to the corresponding PR? (I assume a PR has been merged because of your previous message :) )
Hi, I have been struggling with the same error message and figured out having GraphViz installed on Windows causes some version incompability among the external libraries from GTK+. So after uninstalling GraphViz, it worked for me. See: https://github.com/WhyNotHugo/django-afip/issues/157
Bug description
I installed the library and the GTK project, but it's still throwing an error like
cannot load library 'pango-1.0': error 0x7e. Additionally, ctypes.util.find_library() did not manage to locate a library called 'pango-1.0'
Can anyone let me know the solution?
I'm using python 3.7.x version
Code snippet to reproduce the bug
from doctr.models import ocr_predictor
Error traceback
Environment
I installed the library and when trying to run the code, it's throwing an error
