IOError for OSD (psm 0)

Running pytesseract on Raspbian, python 2.7, tesseract 4.00 (4.00.00dev-625-g9c2fa0d).

My code is as follows:

ret = image_to_string(im,lang='eng',boxes=False, config="-psm 0")

Error:

Traceback (most recent call last):
  File "/home/pi/Vocable/TESTING.py", line 114, in <module>
    ret = image_to_string(im,lang='eng',boxes=False, config="-psm 0")
  File "/usr/local/lib/python2.7/dist-packages/pytesseract/pytesseract.py", line 126, in image_to_string
    f = open(output_file_name, 'rb')
IOError: [Errno 2] No such file or directory: '/tmp/tess_lN5JlN.txt'

If I run code with psm 1 [Recognition with OSD], I receive no errors but the upside down text is simply treated as right-side-up text, producing garbage results. (This was tested on an inverted test.png)

Essentially text recognition works but OSD does not.

@movaid7 I suggest leaving the image_to_string function as it is (logically) - returning text or raising error exception, when there is no txt file. And we can have new function image_to_file - returning list of temp file path strings created by tesseract. (In this case, the user should parse the files manually according to his/her use case)

The orientation parameter is not available with image_to_data, right?
