python FileNotFoundError when using pytesseract
<p>I trying to capture a part of the current screen to detect some number on the screen, but when the code run got this error:</p>

<pre><code>Traceback (most recent call last):
  File "C:/Users/Administrator/PycharmProjects/bot/detect_num.py", line 12, in &lt;module&gt;
    print(pytesseract.image_to_string(Image.open('test.jpg')))

</code></pre>

<p>source code:</p>

<pre><code>import pyscreenshot as ImageGrab
from PIL import Image
import subprocess
from pytesseract import *

if __name__=="__main__":
    im = ImageGrab.grab(bbox=(1349, 34, 1357, 45))
    im = im.convert('1')
    im.save('test.jpg', 'JPEG')
    im.show()
    print(pytesseract.image_to_string(Image.open('test.jpg')))
</code></pre>

<p>Please some one tell me why, and how to fix it?</p>
