python - Camelot python;OSError : exception: access violation writing 0x00000080

Question

我尝试使用 Camelot 从 PDF 文件中提取表格。

这是我的代码:

import camelot
tables = camelot.read_pdf('foo.pdf')
print(tables)

运行此脚本时出现错误，如下所示:

  File "C:/Users/gibin/PycharmProjects/ML/Table_Tester.py", line 20, in <module>
    table=tables = camelot.read_pdf(r"C:\Users\gibin\PycharmProjects\ML\Doc_downloader\GWC_Docs\781313686.pdf")
  File "C:\Users\gibin\AppData\Local\Programs\Python\Python37-32\lib\site-packages\camelot\io.py", line 117, in read_pdf
    **kwargs
  File "C:\Users\gibin\AppData\Local\Programs\Python\Python37-32\lib\site-packages\camelot\handlers.py", line 172, in parse
    p, suppress_stdout=suppress_stdout, layout_kwargs=layout_kwargs

    with Ghostscript(*gs_call, stdout=null) as gs:
  File "C:\Users\gibin\AppData\Local\Programs\Python\Python37-32\lib\site-packages\camelot\ext\ghostscript\__init__.py", line 95, in Ghostscript
    stderr=kwargs.get("stderr", None),
  File "C:\Users\gibin\AppData\Local\Programs\Python\Python37-32\lib\site-packages\camelot\ext\ghostscript\__init__.py", line 39, in __init__
    rc = gs.init_with_args(instance, args)
  File "C:\Users\gibin\AppData\Local\Programs\Python\Python37-32\lib\site-packages\camelot\ext\ghostscript\_gsprint.py", line 169, in init_with_args
    rc = libgs.gsapi_init_with_args(instance, len(argv), c_argv)

OSError: exception: access violation writing 0x00000080

Process finished with exit code 1

我该如何解决这个问题，或者有其他方法从 PDF 中获取表格吗？

编辑:相同的脚本在 jupyter 笔记本中运行良好，但在 pycharm 中不起作用。

您是否通过 PyPI 存储库安装了 Camelot，即 pip install comelot-py[cv]？

从源代码重新安装 Camelot 后，我​​不再收到此错误:

git clone https://www.github.com/camelot-dev/camelot
cd camelot
pip install ".[cv]"
