FileNotFoundError：[WinError 2] | 使用Python，OpenCV和OCR从图像读取文本时出错

Question

I'm having issues with this example code of how to read text from images using Python, OpenCV and OCR.

This code was built with python 2.7, and I'm using python 3.6 so maybe I'm missing some changes between these versions.

import cv2
import numpy as np
import pytesseract
from PIL import Image
src_path = "C:/Users/crist/Desktop/borrar/lectura/"
def get_string(img_path):
# Read image with opencv
img = cv2.imread(img_path)

# Convert to gray
img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

# Apply dilation and erosion to remove some noise
kernel = np.ones((1, 1), np.uint8)
img = cv2.dilate(img, kernel, iterations=1)
img = cv2.erode(img, kernel, iterations=1)

# Write image after removed noise
cv2.imwrite(src_path + "removed_noise.png", img)

#  Apply threshold to get image with only black and white
#img = cv2.adaptiveThreshold(img, 255, cv2.ADAPTIVE_THRESH_GAUSSIAN_C, cv2.THRESH_BINARY, 31, 2)

# Write the image after apply opencv to do some ...
cv2.imwrite(src_path + "thres.png", img)

# Recognize text with tesseract for python
result = pytesseract.image_to_string(Image.open(src_path + "thres.png"))


#os.remove(temp)

return result


print ('--- Start recognize text from image ---')
print (get_string(src_path + "2.png"))

print ("------ Done -------")

Errors:
