Python 画像から文字起こし

pythonで画像から文字起こしする事に挑戦しています。
sample.pyを実行すると下記の通りエラー表示されます。
対応方法をご教示願えないでしょうか。

【sample.py】
from PIL import Image
import sys
import pyocr
import pyocr.builders
tools = pyocr.get_available_tools()
if len(tools) == 0:
print("No OCR tool found")
sys.exit(1)
tool = tools[0]
print("Will use tool '%s'" % (tool.get_name()))
langs = tool.get_available_languages()
print("Available languages: %s" % ", ".join(langs))
lang = langs[0]
print("Will use lang '%s'" % (lang))
txt = tool.image_to_string(
Image.open('abc.png'),
lang=lang,
builder=pyocr.builders.TextBuilder()
)
print(txt)
