tesseract python The system cannot find the file specified

I am running a python test framework that uses Tesseract.

When I run a test that uses tesseract however I get the following error :

WindowsError: [Error 2] The system cannot find the file specified

I managed to go through the logs and found it breaks at:

File "C:\Python27\lib\subprocess.py", line 212, in check_output
process = Popen(stdout=PIPE, *popenargs, **kwargs)
File "C:\Python27\lib\subprocess.py", line 390, in __init__
errread, errwrite)
File "C:\Python27\lib\subprocess.py", line 640, in _execute_child
startupinfo)

The subprocess is called by a non python lib command from the framework

def process_frame_text(single_char=False):
    tess_list = ['tesseract', 'tmp/ocr_image.png', 'tmp/ocr_output']
    tess_list += ['-psm', '10'] if single_char else []
    check_output(tess_list, stderr=STDOUT)[:-1]

I have installed windows Tesseract on my machine at C:\Program Files x86\Tesseract-OCR

Appreciate you ideas.

Thanks

Apparently, subprocess module is not able to find tesseract.exe and invoke it from Windows shell. If path to the executable, C:\Program Files x86\Tesseract-OCR, is not added to Windows environment variables, then modify tess_list to provide full file path.

EDIT:

For your case, should set:

  • TESSDATA_PREFIX = C:\Program Files x86\Tesseract\tessdata that points to the trained language data files.
  • C:\Program Files (x86)\Tesseract-OCR which is the tesseract.exe file path should be added to Windows system PATH variable as an addition value, such as PATH=%PATH%;"C:\Program Files (x86)\Tesseract-OCR" if added by command for temporary use.
