无法从图像中提取文本

Question

我一直在使用tesseract从图像中提取文本的项目。我也在使用python 3.7.7但是我遇到了我无法解决的错误。

tess.pytesseract.tesseract_cmd = r'C:\\Program Files (x86)\\Tesseract-OCR\\tess1\\eng.traineddata'

img = Image.open('C:\\Users\\USER\\PycharmProjects\\selenium\\automation\\screenshot.png')
text = tess.image_to_string(img, lang='eng')

当我运行此程序时出现错误

Traceback (most recent call last):
  File "C:/Users/USER/PycharmProjects/selenium/automation/open.py", line 8, in <module>
    text = tess.image_to_string(img, lang='eng')
