跟我一起学【Python3】之——百度ai+Tesseract-OCR识别图片

1.安装python包

            
              pip install pillow
pip install pytesser3
pip install pytesseract
pip install wheel
pip install baidu-aip
pip install keyboard
            
          

2.安装Tesseract-OCR

3.源码

4.报错解决：pytesseract.pytesseract.TesseractNotFoundError

问题解决：Python\Python36-32\Lib\site-packages\pytesseract 路径下的pytesseract.py文件中，注意反斜杠！！！！

tesseract_cmd = ‘D:/Program Files/Tesseract-OCR/tesseract.exe
