Value error on reshaping image

[rachmadaniHaryono]

Python 2.7.12 (default, Jul 1 2016, 15:12:24)

Traceback (most recent call last):
  File "./noteshrink.py", line 585, in <module>
    main()
  File "./noteshrink.py", line 582, in main
    notescan_main(options=get_argument_parser().parse_args())
  File "./noteshrink.py", line 557, in notescan_main
    samples = sample_pixels(img, options)
  File "./noteshrink.py", line 340, in sample_pixels
    pixels = img.reshape((-1, 3))
ValueError: total size of new array must be unchanged

i have installed all requirements except notescanm which isn't pip installable.

I tried running the script on the photo you attached, and it worked fine.

"notescan" is simply the original name of the repo/project before it was noteshrink, it has now been changed in the requirements.txt.

Not sure why this error is occurring. What output do you see if you insert the line

print '*** image has shape', img.shape, '***'

immediately before line 340?

(Pdb) img.shape
()
(Pdb) type(img.shape)
<type 'tuple'>

update :

i tried once again and now with virtualenv and it is working after i installing noteshrink from requirements. it seems like i can't run noteshrink.py directly without installing it first. is it expected behaviour?

package that installed in my python (non venv)

Pillow==3.3.1
image==1.5.4
numpy==1.11.1
scipy==0.18.1

That's not expected behavior, but I don't quite know why that might be the case. I'm guessing that it's a difference between one of the package versions in your environment and mine, but can't for the life of me think of what it might be.

Closing this for now because you found a work-around.
