🐛 [Bug] Encountered bug when using Torch-TensorRT with a pytorch segmentation model #3254
Description
Hi! I have been using torch_tensorrt for speedup of pytorch models and have been loving it. But sometimes i face problems while conversion.
In this case, i was using segmentation-models-pytorch(smp) library.
import segmentation_models_pytorch as smp
import torch_tensorrt as trt
import torch
model = smp.create_model(
arch="fpn", # name of the architecture, e.g. 'Unet'/ 'FPN' / etc. Case INsensitive!
encoder_name="mit_b0",
encoder_weights="imagenet",
in_channels=3,
classes=3,
).eval().to('cuda')
input_data = torch.randn(1,3,224,224,requires_grad=False).to('cuda')
scripted_model = torch.jit.trace(model, input_data )
trt_model = trt.compile(
scripted_model,
inputs = [trt.Input((1,3,736,1280),precision = torch.float32)],
enabled_precisions={torch.float32},truncate_long_and_double = True)I got the following error.
WARNING:root:Given dtype that does not have direct mapping to torch (dtype.unknown), defaulting to torch.float
WARNING:torch_tensorrt._compile:Input is a torchscript module but the ir was not specified (default=dynamo), please set ir=torchscript to suppress the warning.

RuntimeError: [Error thrown at core/conversion/converters/converter_util.cpp:270] Expected const_layer to be true but got false
This especially occurs when im using mit_b0 as backbone. for other resnet based backbone, im getting good speedups.
Hence I am not much dependant on this backbone but i would love to know why this conversion is failing. If anyone could help in this, it would be helpful.
If anyone interested, output for pip freeze is
