Question

我正在尝试使用pytesseract库执行python代码。它已经由anaconda应用程序安装，但是当我尝试在jupyter笔记本中运行时，我发现tesseract找不到错误。我添加了安装该库的PATH，但没有帮助。

我的代码：

# text recognition
import cv2
import pytesseract
# read image
im = cv2.imread('E:/KT_session/text_img.png')
# configurations
config = ('-l eng --oem 1 --psm 3')
# pytessercat
text = pytesseract.image_to_string(im, config=config)
# print text
text = text.split('\n')

错误：
