python - Pytesser3 でエラーが見つかりません

Question

import pytesser3
import Image
a = Image.open("C:\\Users\\dell\\Desktop\\test.png") 
b = pytesser3.image_to_string(a)
print(b)

簡単な OCR プログラムを作成しようとしましたが、実行するたびに次のエラーが発生します。pytesser3 をアンインストールして再インストールしましたが、何も変わっていません。私は何を間違っていますか？

pytesseract.pytesseract.tesseract_cmd = 'C:\\Users\\dell\\AppData\\Local\\Programs\\Python\\Python36-32\\Lib\\site-packages\\pytesseract'

私はあなたが言ったことをしましたが、今は別のエラーがあります:
