使用python和tesseract的OCR OCr的示例代码 错误

我使用的是Python3，我下载了tesseract库并添加到anaconda库中。但在第一次运行它时，我收到了显示打印缺少括号的错误，所以我改变了这一点，现在我发现这个错误，任何人都可以帮我，这将是非常棒的。 我还在这里添加tesseract包装器的源代码 “”“使用Google的Tesseract引擎在Python中进行OCR

而不是使用：

except errors.Tesser_General_Exception, value:

换成

except errors.Tesser_General_Exception as value:

---

它对我来说很有用。它是关于从

Python2

升级到

Python3

@user10089632和second？。我完全按照tutorialbro中的说明做了。这个问题是我在Python2-lib中使用Python2-lib，不管有什么代码会出现问题，我实际上必须调试整个库。即使在r由于一些问题持续存在，所以我决定使用python2.7，所有的事情都顺其自然

except errors.Tesser_General_Exception, value:

except errors.Tesser_General_Exception as value:
