ValueError in modela/tables.py

[michaelstellanar]

In one of my input pdf files, the following is thrown:

File "/home/michaelt/Work/sandbox_gradio/inference/lib/python3.12/site-packages/unstructured_inference/models/tables.py", line 667, in fill_cells
table_rows_no = max({row for cell in cells for row in cell["row_nums"]})
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: max() iterable argument is empty

Debugging shows that cells array is, indeed, [].

Proposed fix:

table_rows_no = max({row for cell in cells for row in cell["row_nums"]}, default=0)
table_cols_no = max({col for cell in cells for col in cell["column_nums"]}, default=0)

It fixed my problem.

Hi @michaelstellanar, Addressed on #359. You'll need to upgrade unstructured-inference to 0.7.36.
