Python 3.x TypeError:需要类似字节的对象,而不是';str';在python 3.5.2和PyteSeract中
我正在使用pythonPython 3.x TypeError:需要类似字节的对象,而不是';str';在python 3.5.2和PyteSeract中,python-3.x,Python 3.x,我正在使用python3.5.2和PyteSeract,有一个错误TypeError:当我运行代码时,需要一个类似字节的对象,而不是“str”(详细信息如下): 代码:文件“D:/test.py” 错误: Traceback (most recent call last): File "D:/test.py", line 11, in <module> print(pytesseract.image_to_string(Image.open('d:/testimages/
3.5.2
和PyteSeract,有一个错误TypeError:当我运行代码时,需要一个类似字节的对象,而不是“str”
(详细信息如下):
代码:文件“D:/test.py”
错误:
Traceback (most recent call last):
File "D:/test.py", line 11, in <module>
print(pytesseract.image_to_string(Image.open('d:/testimages/name.gif'), lang='chi_sim'))

error_lines = tuple(line for line in lines if line.find('Error') >= 0)
File "C:\Users\dell\AppData\Local\Programs\Python\Python35\lib\site-packages\pytesseract\pytesseract.py", line 112, in <genexpr>
error_lines = tuple(line for line in lines if line.find('Error') >= 0)
TypeError: a bytes-like object is required, not 'str'
这是PyteSeract中的一个已知错误,请参阅: 分析tesseract输出时出现的错误很脆弱:需要类似字节的对象,而不是“str” 及 实际上,tesseract中有一个错误。但是在Python端发生错误是因为error_string返回字节文本,并且geterrors调用似乎有问题 解决方法是安装给定语言的培训数据,请参阅,或通过编辑
site packages\pytesseract\pytesseract.py
并在get\u errors()
函数顶部插入一行额外内容(第109行):
然后,该函数的内容如下:
def get_errors(error_string):
'''
returns all lines in the error_string that start with the string "error"
'''
error_string = error_string.decode("utf-8")
lines = error_string.splitlines()
error_lines = tuple(line for line in lines if line.find('Error') >= 0)
if len(error_lines) > 0:
return '\n'.join(error_lines)
else:
return error_string.strip()
@zwl1619:我不太熟悉Pytesharact的工作原理。修复编码错误表明培训数据未按预期方式安装。以前曾抛出该错误,但由于编码问题,您从未获得该错误。也许是某种许可问题?
