在google colab中运行时pytesseract出错

Question

我已经使用命令在Google colab中安装了tesseract

!pip3 install pytesseract
!pip3 install tesseract-ocr
!sudo apt install libtesseract-dev

然后我运行命令

from pytesseract import image_to_string
import pytesseract

pytesseract.pytesseract.tesseract_cmd = r'/usr/local/bin/pytesseract'

pytesseract.image_to_string(img,  lang='eng', config=r'--oem 3 --psm 7')

然后我得到了错误

---------------------------------------------------------------------------
TesseractError                            Traceback (most recent call last)

Answer 1

pytesseract.pytesseract.tesseract_cmd = r'/usr/bin/tesseract'

img = r“/content/gdrive/MyDrive/images.jpg”

结果 = pytesseract.image_to_string(Image.open(img))) 打印（结果）

您应该在此行之前指定“img 路径”， pytesseract.image_to_string(img, lang='eng', config=r'--oem 3 --psm 7')
