Fatal error: Cannot create infer builder

[sdml0]

I put vs-nnvisr.trt10.dll and contents of deps.windows.trt10.0.7z into one folder. When I try to use it I get "VapourSynth encountered a fatal error: Cannot create infer builder" What am I missing? By assembling everithing for trt8 in one folder I've got: Property read unsuccessful due to missing key but no error output: _DurationNum. vs-mlrt works fine in the same environment. And is it no settings for trtexec?

For the first issue, please provide more information by enable debug logging and share the output. You can add the following lines at the beginning of your script to get debug log:

def log_debug(typ, msg):
    if typ == 0:
        print(f"Debug: {msg}")
core.add_log_handler(log_debug)

Also, TensorRT 10 only supports Volta or newer GPUs (that is, at least 20 series for GeForce).

For the second issue, _DurationNum should be set by the source filter and always be there. Can you share the following?

• Your processing script
• Your VapourSynth, and source filter version
• Your video file, or MediaInfo output of your video file

Aaa.... model_path != models, model_path must contain folder models. trt8 issue resolved. Nefarious NVencC hides messages from vpy, shows only errors.

When I launch vs-nnvisr.trt10.dll from vs-mlrt's vsmlrt-cuda folder it works!!!
