cannot use Python API to infer after converting the segmentation model to tensorrt

[chenzhutian]

After converting to tensorrt format, I try to do inference using the mmdeploy's python API. However, it shows

It looks like it is because mmdeploy's runtime doesn't support ResizeToMultiple. Can you please share the inference code with the public? Thanks!
