Why a numpy array appears to have no shape?

I understand the following:

import numpy as np

arr = np.array([[1, 2, 3, 4], [5, 6, 7, 8]])

print(arr.shape)

Output:

(2, 4)

So I was wondering why I get the following:

import numpy

import pytesseract
import logging

# Raw call does not need escaping like usual Windows path in python 
pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract'

logging.basicConfig(level=logging.WARNING)
logging.getLogger('pytesseract').setLevel(logging.DEBUG)


image = r'C:\ocr\target\31832_226140__0001-00002b.jpg'
target = numpy.asarray(pytesseract.image_to_string(image, config='--dpi 96 --psm 6 -c preserve_interword_spaces=1 -c tessedit_char_whitelist="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.,- \'" '))
print("target type is:",type(target))
print("target array shape is:",target.shape)

Output:

DEBUG:pytesseract:['C:\\Program Files\\Tesseract-OCR\\tesseract', 'C:\\ocr\\target\\31832_226140__0001-00002b.jpg', 'C:\\Users\\david\\AppData\\Local\\Temp\\tess_p68ogbz9', '--dpi', '96', '--psm', '6', '-c', 'preserve_interword_spaces=1', '-c', "tessedit_char_whitelist=abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.,- '", 'txt']
target type is: <class 'numpy.ndarray'>
target array shape is: ()

Okay. My array is text. But I still would have thought I would get parameter's example like say (1,999) for my shape?

Using the line print(target) gives the following type of output.

Solution

This just means that you've created a scalar, i.e., an array with "no shape". Consider:

>>> import numpy as np
>>> arr = np.array(1)
>>> arr
array(1)
>>> arr.shape
()

This is because, I can only surmise, pytesseract.image_to_string returns a str object (or maybe a bytes object). So of course, you get:

>>> np.asarray("some string object")
array('some string object', dtype='<U18')
>>> np.asarray("some string object").shape
()

It isn't clear exactly what you expect to create. As you stated, you just have a text file, presumably, so why are you trying to create a numpy.ndarray object out of it? If you can elaborate on what you are trying to achieve, perhaps I or others can suggest an approach.
