[BUG] BasicVSR : "Explicitly instantiated a Cache" / Model not downloaded?

[tailland]

Hybrid Build: 11.7.2025

Reproduce:
Activate BasicVSR filter, on preview throws:
"Explicitly instantiated a Cache. This is no longer possible and the original clip has been passed through instead."
in addition, there seems to be a problem with the availability of the model files?
i have newest hybrid + addons installed.

BasicVSR++ is not the same as BasicVSR.

Explicitly instantiated a Cache. This is no longer possible and the original clip has been passed through instead.

Isn't caused by BasicVSR++, but TIVTC (more precise TFM).

in addition, there seems to be a problem with the availability of the model files?

Are you sure you downloaded and extracted everything properly?
"Hybrid\64bit\Vapoursynth\Lib\site-packages\vsbasicvsrpp\models"
does contain:

• basicvsr_plusplus_c128n25_ntire_decompress_track1_20210223-7b2eba02.pth
  
• basicvsr_plusplus_c128n25_ntire_decompress_track2_20210314-eeae05e6.pth

• spynet_20210409-c6c1bd09.pth
  

here, same as in "VapoursynthR72_torch_2025.06.16".
Hybrid does not download anything, all models&co are pre-downloaded.

=> can't produce the problem.

checked the downloaded archive..  that should be the explanation?

[Selur]

Those seem to be the files I listed, that I got here. So no, that does not seem to explain the crash on your end.

[tailland]

oh ok i thought the 0 byte filesize was the problem

[Selur]

Ahh,.. I totally overlooked that.
-> will fix
(you can also call: "python -m vsbasicvsrpp" inside a terminal in the Vapoursynth folder)

Uploading a new torch addon which includes the files,.. should be up in ~1hour.

cool.
(the manual download worked, too btw)
