我试图使用Tika运行简单的代码解析行,以解析PDF中的文本(在此示例中命名为outputFileName)。这曾经运行没有错误。我最近将我的笔记本电脑发送到我们的IT部门进行软件更新,并且不得不树脂化Anaconda并导入某些模块(例如2019年11月9日发布的Tika 1.22)来运行我的代码。我还从Tika导入了解析器。这是代码行和我收到的错误消息:
代码:
#从pdf文件中解析文本以供使用
pdftext = parser.from_file(outputFileName)
错误
AttributeError Traceback (most recent call last)

我还下载了Java 8。
tika.py源代码是否存在问题?还是我错过了需要安装的东西?任何帮助将不胜感激。
答案 0 :(得分:4)
只需安装tika的早期版本。我有同样的问题,对我有用。怎么样?转到终端并输入pip install tika==1.19

更新tika python库后,我也收到此错误,如果您需要临时修复,我建议降级至1.19版
