Python : OSError: [Errno 2] No such file or directory

Question

I am using pytesseract lib to extract text from image. This works fine when I am running code on localhost. But gives me above error when I deploy on openshift.

Below is code what I have written so far.

try:
  import Image
except ImportError:
  from PIL import Image
import pytesseract
filePath = PATH_WHERE_FILE_IS_LOCATED # '/var/lib/openshift/555.../app-root/data/data/y.jpg'
text = pytesseract.image_to_string(Image.open(filePath))  # this line produces error

Traceback of above error is

>>> pytesseract.image_to_string(Image.open(filePath))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/var/lib/openshift/56faaee42d527151d5000089/app-  root/runtime/repo/pytesseract/pytesseract.py", line 132, in  image_to_string

File "/var/lib/openshift/56faaee42d527151d5000089/app-root/runtime/repo/pytesseract/pytesseract.py", line 73, in run_tesseract

errread, errwrite)
File "/opt/rh/python27/root/usr/lib64/python2.7/subprocess.py", line 1327, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory

But Image.open(filePath) returns object reference

 <PIL.PngImagePlugin.PngImageFile image mode=RGBA size=1366x768 at 0x7FC5A9F719D0>

How to remove this error ? thanks in advance!!

Answer 1

Either you don't have tesseract-ocr installed on "openshift", or it is not in your PATH. See https://pypi.python.org/pypi/pytesseract/0.1 Check that you can execute tesseract command from command line.

Answer 2

As mentioned here install tesseract-ocr

You can rhc ssh to run commands. More windows specific details can be found here.
