Tensorrt engine

[imsiddhant07]

I tried running TRT based-off three methods:

1. python src/transformer-deploy/convert.py
2. exisiting docker image
3. build docker image from repo

In all three instances, I got back the same response while running TRT backend.

The command I have been trying to run (docker for example):

docker run -it --rm --gpus all -v $PWD:/project ghcr.io/els-rd/transformer-deploy:latest bash -c "cd /project && \
  convert_model -m \"sentence-transformers/multi-qa-distilbert-cos-v1\" \
  --backend tensorrt onnx \
  --seq-len 128 128 256 \
  --batch-size 1 32 300"

When i pass only 'onnx' as backend param everything runs pretty smoothly. But face issues with 'tensorrt' backend.

TypeError: deserialize_cuda_engine(): incompatible function arguments. The following argument types are supported:
    1. (self: tensorrt.tensorrt.Runtime, serialized_engine: buffer) -> tensorrt.tensorrt.ICudaEngine

Would be great if I could have a workaround for this.

Python: 3.8.15

Also, not sure if this helped.
