import tabula

df = tabula.read_pdf(filepath, pages = 5 ,guess=True, multiple_tables= True, stream=True, java_options="-Dfile.encoding=UTF8")
print(df)
预期输出:获取特定页面的表格。
【问题讨论】:
-
运气好吗?我遇到了同样的错误。
-
没有运气肖恩。这是 PDF 格式错误,而不是代码错误。我与处理 Tabula 库的开发人员团队进行了协调,他们告诉我 PDF 格式略有损坏,因此 tabula 无法处理 PDF。
-
我在 Raspberry Pi 设置中遇到了同样的错误。但是,当我通过 Mac 终端处理相同的文件时,我没有收到错误消息。两种环境都运行 tabula 2.2.0 版。恕我直言,我不相信这是用户 1958031 所述的 PDF 格式错误,因为相同版本的 tabula 在一个环境中对我有用,而在另一个环境中处理相同文件时失败。两种情况下的 PDF 格式相同。
