Problem to use sift in Vlfeat about pcv

[jesolem]

Did you add the full (absolute) path to the env variable?

Yes, I do. I test it under Windows 7 OS. After I add the full path to the env variable, It throws these error:

Traceback (most recent call last):
  File "F:/dropbox/Dropbox/translation/pcv-notebook/ch02/ch02_sift.py", line 14, in <module>
    l1, d1 = sift.read_features_from_file('empire.sift')
  File "C:\Python27\lib\site-packages\PCV\localdescriptors\sift.py", line 30, in read_features_from_file
    f = loadtxt(filename)
  File "C:\Python27\lib\site-packages\numpy\lib\npyio.py", line 729, in loadtxt
processed tmp.pgm to empire.sift
    fh = iter(open(fname, 'U'))
IOError: [Errno 2] No such file or directory: 'empire.sift'

The error indicates it doesn't find the sift.exe. To solve this problem, I bulid a folder .\\utils\\win32vlfeat\\sift.exe to contains the VLfeat. It's here. I don't think it's not a good way to solve this problem. Is there a perfect way to solve this problem?

It's a good way to this question， I think。

It works, but not perfect. I hope to find a method which doesn't need to modify the source code sift.py of library PCV.

People seem to have problems with the VLFeat executable. I'm going to try to replace that for the next edition. Thanks all.

Great, I can't wait to read it.

@jesolem yes, I would love to read your next edition where you can replace the VLFeat executable by something less platform dependent. Thanks!
