运行OCR Python

Question

我正在尝试用Python制作一些OCR。我在网上找到了这个代码，我想怎么做就怎么做。但是当我尝试运行它时，我收到了这个错误消息。你知道吗

请留下我的密码：

import io 
from PIL import Image
import pytesseract
from wand.image import Image as wi
pdf = wi(filename="test1(citibank).pdf", resolution=300)
pdfImage = pdf.convert('jpeg')
imageBlobs = []

for img in pdfImage.sequence:
    imgPage=wi(image=img)
    imageBlobs.append(imgPage.make_blob('jpeg'))

recognisedtext = []

for imgBlob in imageBlobs:
    im = Image.open(io.BytesIO(imgBlob))
    text = pytesseract.image_to_string(im, lang='es')
    recognisedtext.append(text)

print(recognisedtext[1])
