Not able to run crop_morphology.py

[kaushikmit]

I get an error while compiling crop_morphology.py . It also shows undefined error with the print statements.

It also shows an error in the following line:
borders.sort(key=lambda (i, x1, y1, x2, y2): (x2 - x1) * (y2 - y1))

Can anyone help me in running this file successfully ?

Sounds like a Python 2/3 issue.

I may be having a similar issue.

First, PIL seems to have been replaced by Pillow, so I changed that import on line 24 to indicate Pillow instead.

Since that was in python 3 on my system, I changed the first line to

#!/usr/bin/env python3

Now I get the error:

  File "Downloads/crop_morphology.py", line 168
    print '%d %s -> %s / %s (%s), %s -> %s / %s (%s), %s -> %s' % (
                                                              ^
SyntaxError: invalid syntax

My python skills are minimal, so I don't immediately see what's wrong with that print statement. Or maybe it's something else?

Try using 2to3 to convert the script from Python 2 to 3 (worked for me when getting the same error). To make the changes persistent:

2to3 crop_morphology.py -w

P.S. Just found a Python3 version!

It is a python 2 -> 3 issue. The solution is considering how to access the values inside the tuple object borders:

    # https://www.python.org/dev/peps/pep-3113/
    borders.sort(key=lambda x: (x[3] - x[1]) * (x[4] - x[2]))

That user doesn't seem to be on GitHub anymore. Maybe this?
