@kunyue001 ,please make sure your vcpkg is latest, and I can confirm you downloaded package is broken.Can you please test if you can extract C:/Users/Kun/vcpkg/downloads/temp/darknet-cache/yolov4-tiny.weights manually?
Thanks.

[cenit]

Exactly as @JonLiu1993 said. You need to do a git pull inside vcpkg folder and then retry the command

I have tired git pull in the vcpkg folder.

Exactly as @JonLiu1993 said. You need to do a git pull inside vcpkg folder and then retry the command

I have updated it using git pull. It gives me the same error.

[cenit]

Yes you're right. I don't know what happened. Might be that github modified the archive somehow? I already have a darknet update PR in the pipeline, I will add correct hashes!
In the meantime, please correct the portfile with the hashes the download gives you and then retry

[JonLiu1993]

@kunyue001 ,After @cenit 's pr merge, you can update vcpkg and try again.

[soltkreig]

Did anyone solve this trouble? I can't install darknet on local machine

[vicroms]

Make sure that you have the latest portfiles by doing a git pull.
If the error persists try deleting the downloaded darknet sources in {vcpkg-root}/downloads/. As a last option you can overwrite the SHA by modifying {vcpkg-root}/ports/darknet/portfile.cmake.

[MiguelEsteve]

Does not work to me in any of the cases mentioned above.
Neither doing a git pull, nor overwritting the SHA. Stop using vcpkg.

[sfhacker]

We have just built darknet master branch from source (Windows 10 x64) with no issues at all.

File does not have expected hash:

      File path: [ C:/Users/Kun/vcpkg/downloads/temp/darknet-cache/yolov4-tiny.weights ]
  Expected hash: [ 804ca2ab8e3699d31c95bf773d22f901f186703487c7945f30dc2dbb808094793362cb6f5da5cd0b4b83f820c8565a3cba22fafa069ee6ca2a925677137d95f4 ]

Possiable solution to the issue:

1. Delete the archive files 'C:/Users/Kun/vcpkg/downloads/temp/darknet-cache/yolov4-tiny.weights', you can see the information from output.

--  File path: [ C:/Users/Kun/vcpkg/downloads/temp/darknet-cache/yolov4-tiny.weights ]

2. Executing 'git pull' to get latest version of portfile.

3. You can try again, if it still persists, you can overwrite the SHA by updating {vcpkg-root}/ports/darknet/portfile.cmake with 'Actual hash: [ 7d4d9fe150f9fe3ea7d2310f1445fe983b31fbf06d301c70ecfe00e8559e6f1bf940198c2dd55db772238f23ea0092fb6553558e5414'.

@@kunyue001 @soltkreig, we have already fixed this issue on master, please reopen this issue if the issue persist.

[PhoebeHui]

This issue fixed by PR #15296

[vicroms]

@PhoebeHui we need to add a version string to the downloaded filename (yolov4-tiny.weights) or this may keep happening, maybe prefixing DARKNET_VERSION is enough (assuming that the contents of the weights file and the library change at the same time).

Since the filename is the same, vcpkg doesn't know that it has to re-download the file.

 vcpkg_download_distfile(YOLOV4-TINY_WEIGHTS
    URLS "https://github.com/AlexeyAB/darknet/releases/download/darknet_yolo_v4_pre/yolov4-tiny.weights"
    FILENAME "darknet-cache/${DARKNET_VERSION}-yolov4-tiny.weights"
    SHA512 xyz
  )

[PhoebeHui]

@vicroms, I'm agree with you, however, PR #16635 is talking about to change the way to get the required files, the hash may not needed in future, so this is will not be an issue. I will keep tracking the PR, and see if this is needed.
