Fetcher error for Python PyQt package from sourceforge

Hi,

I am getting fetcher error for python-pyqt_5.3.1.bb when i am building with renasas R-car M3 .The error is showing as

ERROR: python-pyqt-5.3.1-r1 do_fetch: Fetcher failure for URL: 'http://downloads.sourceforge.net/projects/pyqt/files/PyQt5/PyQt-5.3.1/PyQt-gpl-5.3.1.tar.gz'. Checksum mismatch!
File: '/home/user/genivi-dev-platform/gdp-src-build/downloads/PyQt-gpl-5.3.1.tar.gz' has md5 checksum f3d6da4a1d5bc84e0117e4c60e5a613a when c24b1a4040292fcfdbf128a9a5a38e66 was expected
File: '/home/user/genivi-dev-platform/gdp-src-build/downloads/PyQt-gpl-5.3.1.tar.gz' has sha256 checksum 45e67ddeb5f5bf897168490f844eba4027590f90528886128887c2518d9d0efb when 187bc5b3e4e49e6b4ab1d5b20d33c5d0895524cf033dd21df193f6512abb19e8 was expected
If this change is expected (e.g. you have upgraded to a new version without updating the checksums) then you can use these lines within the recipe:
SRC_URI[md5sum] = "f3d6da4a1d5bc84e0117e4c60e5a613a"
SRC_URI[sha256sum] = "45e67ddeb5f5bf897168490f844eba4027590f90528886128887c2518d9d0efb"
Otherwise you should retry the download and/or check with upstream to determine if the file has become corrupted or otherwise unexpectedly modified.
