🐛 [Bug] TRT Error when compiling ViT with Dynamic Shape #3016

Closed Hukongtao closed 1 month ago

Hukongtao commented 1 month ago

Bug Description

To Reproduce

Minimal reproducible code：

import torch
import torch_tensorrt
from transformers import ViTForImageClassification

model = ViTForImageClassification.from_pretrained('google/vit-base-patch16-224')
model = model.eval().cuda()

inputs = [
    torch_tensorrt.Input(
        min_shape=[1, 3, 224, 224],
        opt_shape=[4, 3, 224, 224],
        max_shape=[16, 3, 224, 224],
        dtype=torch.float32
    )
]
# inputs = torch_tensorrt.Input(shape=[2, 3, 224, 224], dtype=torch.float32)
trt_gm = torch_tensorrt.compile(model, "dynamo", inputs)

Expected behavior

Model should compile with Dynamic shapes. But I got error:

WARNING:torch_tensorrt.dynamo._compiler:Some nodes do not have metadata (shape and dtype information). This could lead to problems sometimes if the graph has PyTorch and TensorRT segments.

Looking forward to your reply

@Hukongtao This error is because our lowering pass was not copying over the metadata of the attention op to its replaced variant. I've pushed a fix now to the same PR : https://github.com/pytorch/TensorRT/pull/3019. Can you give it a try ?
