Python Tesseract "No such file or directory"

I'm trying to make an OCR program in python, and I'm using pillow to make an image high contrast black and white, but when I try to use tesseract to extract the text, I get the following error output in terminal:

Error

Traceback (most recent call last):
  File "OCR.py", line 41, in <module>
    print(pytesseract.image_to_string(img))

Python

from PIL import Image
import numpy as np
import pytesseract

sens = int(input("Sensitivity (0-255): "))

im = Image.open("book.jpg")
pixels = np.asarray(im)
width, height = im.size

px = pixels.mean(axis=2)
ppx = px.flatten()


for i in range(ppx.size):
    if ppx[i] > sens:
        ppx[i] = 255
    else:
        ppx[i] = 0


pixels = ppx.reshape(height, width)

img = Image.fromarray(np.uint8(pixels))
img.show()
img.save("images2.jpg")

print(pytesseract.image_to_string(img))

    According to the README, you must install tesseract to use pytesseract.

    On Ubuntu:

    sudo apt install tesseract-ocr
