I am attempting to deploy my Streamlit app and am receiving the following error:

My requirements.txt is:

dlib==19.23.0
imutils==0.5.4
numpy==1.21.2
opencv_python==4.5.5.62
Pillow==9.0.1
streamlit==1.6.0
datetime
pathlib

I can’t find anyone online with the same issue. Any help would be greatly appreciated. Thank you.

Hey @Defqon7

This seems like a conflict with the Pathlib library.
It actually comes pre-installed with Python and when seperately installed, results in this error.
I would suggest you to remove it from the requirements file and try deploying again.

Read this discussion here (python - Weasyprint get undefined property at invoking write_pdf: "AttributeError: 'PosixPath' object has no attribute 'read_text'" - Stack Overflow) to know more.

Best,
Kanak
