新版 Tesserac 略有更正，請將第 2 列程式如下修正：
ocr = subprocess.Popen("tesseract media\\text1.jpg media\\result", shell=True)

依建議修改 captcha1.py 有錯誤!

runfile('D:/Python book/本書範例/ch12/captcha1.py', wdir='D:/Python book/本書範例/ch12')
Traceback (most recent call last):

  File "<ipython-input-7-1a14b3897674>", line 1, in <module>

  File "D:/Python book/本書範例/ch12/captcha1.py", line 26, in <module>
    text = open('result.txt').read().strip()

FileNotFoundError: [Errno 2] No such file or directory: 'result.txt'

相同的，24 列修改為：
child = subprocess.Popen('tesseract media\\bank_t.jpg result', shell=True)  #OCR辨識

改26行 後 ok
text = open('media\\result.txt').read().strip()
