How to use openmodeldb.info models?

[feed0]

I cannot use openmodeldb.info models

1. I downloaded the 4x-UltraSharp.pth and 4x-Fabric.pth files from openmodeldb.info;
2. Placed them in the /weights folder;
3. Fixed the import statement in basicsr (... functional_tensor ... -> ... functional ...);
4. But it does not seem to work with

!python inference_realesrgan.py \
  -n RealESRNet_x4plus \
  -i /kaggle/working/photos \
  --model_path weights/4x-UltraSharp.pth \

Error thrown

- /kaggle/working/Real-ESRGAN/realesrgan/utils.py:63: FutureWarning: You are using `torch.load` with `weights_only=False` (the current default value), which uses the default pickle module implicitly. 
- It is possible to construct malicious pickle data which will execute arbitrary code during unpickling (See https://github.com/pytorch/pytorch/blob/main/SECURITY.md#untrusted-models for more details). 
- In a future release, the default value for `weights_only` will be flipped to `True`. 
- This limits the functions that could be executed during unpickling. 
- Arbitrary objects will no longer be allowed to be loaded via this mode unless they are explicitly allowlisted by the user via `torch.serialization.add_safe_globals`. 
- We recommend you start setting `weights_only=True` for any use case where you don't have full control of the loaded file. 
- Please open an issue on GitHub for any issues related to this experimental feature.
  
loadnet = torch.load(model_path, map_location=torch.device('cpu'))

In spite of that, the default model works fine when upscaling a 24MP image to 384MP with:

!python inference_realesrgan.py \
  -n RealESRNet_x4plus \
  -i /kaggle/working/photos \
  --outscale 4 \
  --tile 1024 \
  --tile_pad 20 \
