tabula-py CalledProcessError: Command '['java', '-Dfile.encoding=UTF8', '-jar',

[kdshreyas]

Summary of your issue

I encountered an issue while processing a PDF file where a specific page consistently triggers a "CalledProcessError" with the following command: ['java', '-Dfile.encoding=UTF8', '-jar']. This error disrupts the processing flow and prevents further execution.

CalledProcessError: Command '['java', '-Dfile.encoding=UTF8', '-jar', 'D:\Anaconda\envs\dev_env\lib\site-packages\tabula\tabula-1.0.5-jar-with-dependencies.jar', '--pages', '1', '--lattice', '--format', 'JSON'

What did you do when you faced the problem?

Code:

inputpdf = 'test_pdf_output.pdf'
page = 1
tables = tabula.read_pdf(inputpdf, pages = page, lattice = True, guess = False)
df = tables[0]

Expected behavior:

The command should execute successfully on the page of the PDF file, without encountering any errors.

Actual behavior:

The error "CalledProcessError" is encountered when processing the specified page within the PDF file.

Thanks for reporting the issue.

It looks like this is the tabula-java issue, which happens with he specific PDF. I can find similar issue in their repo.
tabulapdf/tabula-java#218

Would you mind if you could provide the PDF and report it on tabula-java?

[chezou]

Okay, I confirmed the issue happens with --lattice option for tabula-java with the file. It doesn't raise an error without --lattice option.

This should hit some issues on tabula-java side.

Close as tabula-py doesn't have any workaround.

Hey @chezou,

Thanks for the quick reply, I have created a issue tabulapdf/tabula-java#529 as suggested.
