我试图用Camelot从PDF文件提取表。
这是我的代码：
import camelot
tables = camelot.read_pdf('foo.pdf')
print(tables)
并且在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

rc = libgs.gsapi_init_with_args(instance, len(argv), c_argv)
OSError: exception: access violation writing 0x00000080

如何解决这个问题，或者还有另一种方法可以从PDF获取表格？
编辑：相同的脚本在jupyter笔记本中工作正常，但在pycharm中不工作。
最佳答案
您是否通过PyPI存储库（即pip install camelot-py[cv]）安装了Camelot？
从源代码重新安装Camelot之后，我停止出现此错误：
git clone https://www.github.com/camelot-dev/camelot
cd camelot
pip install ".[cv]"
