报错信息
pytesseract.pytesseract.TesseractError: (1, 'Error opening data file C:\\Program Files\\Tesseract-OCR\\tessdata/chi_sim.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory. Failed loading language \'chi_sim\' Tesseract couldn\'t load any languages! Could not initialize tesseract.')
解决办法
path="img\\text-img.png"testdata_dir_config='--tessdata-dir "C:\\ProgramFiles\\Tesseract-OCR\\tessdata"'textCode=pytesseract.image_to_string(Image.open(path), config=testdata_dir_config, lang='chi_sim')
若不能使用，配置环境变量
Tesseract-OCRC:\ProgramFiles\Tesseract-OCR\tessdata
安装 pytesseract 模块
pipinstallpytesseract-ihttp://pypi.douban.com/simple--trusted-hostpypi.douban.com
安装Tesseract OCR
下载地址：https://github.com/UB-Mannheim/tesseract/wiki点击“tesseract-ocr-w64-setup-v4.0.0-beta.1.20180414.exe”下载安装。注意：安装的时候选中中文包（安装时把所有选项都勾上）。本人安装目录：C:\ProgramFiles\Tesseract-OCR\tessdata使用命令，查看版本号和支持语言：cdC:\ProgramFiles\Tesseract-OCRtesseract-vtesseract--list-langs-vtesseract--list-langs # 查看Tesseract-OCR支持语言
配置tesseract运行文件
...\Lib\site-packages\pytesseract\pytesseract.py找到文件：tesseract_cmd='tesseract'修改为：tesseract_cmd='C:\\Program Files\\Tesseract-OCR\\tesseract.exe'你放tesseract.exe的路径

识别中文时，如果还是报错，可以将中文包下载到本地。
