What version that is still working? Thank you @Arslan-Mehmood1

[christinestraub]

What versions of unstructured and unstructured-inference libraries are you using?

[theogiraudon]

I've got the same error with unstructured@0.15.14 and unstructured-inference@0.7.40

[Qwedon]

The problem occurs from unstructured-inference@0.7.37. With unstructured-inference@0.7.36 and below everything works.

Snippet of code in which error occurs:

from unstructured.partition.pdf import partition_pdf
filename = "your_pdf.pdf"

elements = partition_pdf(
    filename=filename,
    strategy="hi_res", 
    infer_table_structure=True, 
    model_name="yolox"
)

[chung-codes]

I've got the same error with unstructured@0.15.14 and unstructured-inference@0.7.40

i have same issue with same condition

[Arslan-Mehmood1]

What version that is still working? Thank you @Arslan-Mehmood1 @amysudarat amysudarat

unstructured==0.15.10 unstructured_inference==0.7.36

Actually, the problem was with unstructured_inference. I traced back to the time the code worked for me and then I check the available version of unstructured_inference that was released around that time.
