Installed Comfyui-upscaler-tensorrt from COmfyui, and i have the upscale models that are recommended on the github page, but when i try to use them, i get this error - [Errno 2] No such file or directory: '/mnt/Backup_2.73TB/AI/ComfyUI/models/tensorrt/upscaler/4x_foolhardy_Remacri_fp16_1x3x256x256_1x3x512x512_1x3x1280x1280_10.9.0.34.trt'

It seems the example workflow works fine, but if i try to upscale my hidream gguf images generated by ksampler, then it gives me this error

Do we have to rename these upscale models?

[yuvraj108c]

hmm are you using the latest version of the node? It should build the required engine automatically if not found

[zono50]

i'm using the one that is in comfyui the nightly version 2025-04-30

[yuvraj108c]

Try installing the latest version manually, i'm not sure what version you're using, post the full error log I just tested, and it works as expected

@yoges283 what gpu are you using?

[henrikvilhelmberglund]

I had the same issue with a 4060, but worked when creating the engine outside of ComfyUI -

(this is for the portable version, ran with ..\..\..\python_embeded\python.exe -s .\scripts\export_trt_portable.py in the folder for the extension)

import torch
import time
import os, sys
sys.path.append(os.path.dirname(__file__))
from trt_utilities import Engine
import tensorrt

def export_trt(trt_path=None, onnx_path=None, use_fp16=True):
    if trt_path is None:
        trt_path = input("Enter the path to save the TensorRT engine (e.g ./realesrgan.engine): ")
    if onnx_path is None:
        onnx_path = input("Enter the path to the ONNX model (e.g ./realesrgan.onnx): ")

    engine = Engine(trt_path)

    torch.cuda.empty_cache()

    s = time.time()
    ret = engine.build(
        onnx_path,
        use_fp16,
        enable_preview=True,
        input_profile=[
            {"input": [(1,3,256,256), (1,3,512,512), (1,3,1280,1280)]}, # any sizes from 256x256 to 1280x1280
        ],
    )
    e = time.time()
    print(f"Time taken to build: {(e-s)} seconds")

    return ret

export_trt(trt_path="../../models/tensorrt/upscaler/4x_foolhardy_Remacri.engine",
onnx_path="../../models/onnx/4x_foolhardy_Remacri.onnx", use_fp16=True)

this worked, and then it worked in ComfyUI too (which created the engine again as my specified filename was not correct). Very confusing...

Edit: I noticed the engine built within ComfyUI was extremely slow (~5.5x slower than the core .pth upscale) and had a different file size than the engine I built outside of ComfyUI (in ComfyUI: 36823kb, outside ComfyUI: 37019kb), after replacing the slow file with the one built outside it was ~2.5x faster. No idea why this happened! Edit2: The slowdown seems like a VRAM issue.
