我试图从一系列PDF文件中提取表，但无法使tabula py工作。我一直试图通过Windows操作系统上的Jupyter笔记本来使用它。不幸的是，我也一样‘FileNotFoundError’

每次我尝试使用read_PDF()时。

从目前为止我在网上发现的情况来看，这个错误似乎是在尝试运行tablajava文件时产生的。我已经正确安装了java。

我们将非常感谢您的帮助。

这是我试图运行的代码：from tabula import read_pdf

df = read_pdf("https://github.com/tabulapdf/tabula-java/raw/master/src/test/resources/technology/tabula/arabic.pdf")

错误消息：FileNotFoundError Traceback (most recent call last)
