import camelot camelot.read_pdf('file_name.pdf',pages='all', flavor='lattice') when i tried to run the command in LINUX machine i am facing a issues like 'Segmentation fault ' SIGSEGV error... could some one help me out ?

@vinayak-mehta could you please have look , if you get a chance

Hey guys, thanks for your promising tool. Unfortunately, I'm not able to test it, as I also getting a seg fault on Linux (Manjaro), just Tried this:

import camelot

tables = camelot.read_pdf('test.pdf')

I attached test.pdf. I'm using Anaconda with python 3.7 and installed camelot in 0.7.3.

I'm also receiving the same issue when attempting to run python script from command line. Attempts to execute within Jupyter result in the kernel dying.

I have however been successful using the CLI as documented here. Ex: camelot --format csv --output foo.csv lattice input.pdf

Still hoping that someone can assist with the segmentation fault though.

UPDATE: Here are the segmentation fault details:

'>>> tables = camelot.read_pdf(pdf)' 'Fatal Python error: Segmentation fault' 'Current thread 0x00007f45e0b46740 (most recent call first): File "/opt/anaconda3/lib/python3.7/site-packages/camelot/ext/ghostscript/_gsprint.py", line 171 in init_with_args' ' File "/opt/anaconda3/lib/python3.7/site-packages/camelot/ext/ghostscript/init.py", line 39 in init' ' File "/opt/anaconda3/lib/python3.7/site-packages/camelot/ext/ghostscript/init.py", line 95 in Ghostscript' ' File "/opt/anaconda3/lib/python3.7/site-packages/camelot/parsers/lattice.py", line 220 in _generate_image' ' File "/opt/anaconda3/lib/python3.7/site-packages/camelot/parsers/lattice.py", line 403 in extract_tables' ' File "/opt/anaconda3/lib/python3.7/site-packages/camelot/handlers.py", line 172 in parse' ' File "/opt/anaconda3/lib/python3.7/site-packages/camelot/io.py", line 117 in read_pdf' ' File "", line 1 in ' 'Segmentation fault'

Success! I was able to resolve the segmentation error by specifying which 'flavor' to use when reading the table (lattice vs. stream).

As an example: tables = camelot.read_pdf(pdf, flavor='stream')

Thank you @nadolsw ! It really works!

[Binhao-Wang]

But it seems the flavor='lattice' still doesn't work. Anyone helps?

Any idea how to fix this ? I need the lattice flavor for parsing the pdf.

I see this problem running Ubuntu 20.04 as well. lattice flavor always results in seg fault although with much less info than the above. I just get Segmentation fault (core dumped) when I use lattice either through cmd, python shell, or in a script.
