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.’)

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-OCR
C:\\Program Files\\Tesseract-OCR\\tessdata 

安装 pytesseract 模块

pip install pytesseract -i http://pypi.douban.com/simple --trusted-host pypi.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:\\Program Files\\Tesseract-OCR\\tessdata

使用命令，查看版本号和支持语言：
cd C:\\Program Files\\Tesseract-OCR  
tesseract -v tesseract --list-langs -v tesseract --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

Github地址：https://github.com/UB-Mannheim/tesseract/wiki

识别中文时，如果还是报错，可以将中文包下载到本地。
