Error running python script in terminal: OSError: [Errno 2] No such file or directory

I'm trying to use a piece of software called "bundler_sfm" which is executed using a python script.

The software I'm trying to use is available here, the script is in the utils directory if you want to have a look.

When trying to run it I get the following python error:

File "/usr/lib/python2.7/subprocess.py", line 493, in call
return Popen(*popenargs, **kwargs).wait()
File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory

The code that leads to this error is as follows:

# Extract SIFT data
if verbose:
    with open(pgm_filename, 'rb') as fp_in:
        with open(key_filename, 'wb') as fp_out:
            subprocess.call(BIN_SIFT, stdin=fp_in, stdout=fp_out)

I've looked at various other answers with similar errors but am still at a loss on how to fix this problem.

I'm trying to run this in the terminal on elementary OS.

Any assistance would be greatly appreciated.

Already worked it out in the comments, but just for an answer:

Worked out the location where the utility thinks the sift binary is located by printing out BIN_SIFT before calling subprocess.call() method.

Realized this path was incorrect

As a hackish work-around, hard code the correct path to line 55 of bundler.py as a string inside of a list:

BIN_SIFT = ["/real/path/to/sift"]
