Describe the bug

couldn't configure the model with TurbomindEngineConfig and the error shows RuntimeError: Error: turbomind has not been built with fp32 support. With PytorchEngineConfig it's ok to run the code.

Reproduction

I simply run the following code and nothing special:

from lmdeploy import pipeline, TurbomindEngineConfig
from lmdeploy.vl import load_image

model = 'OpenGVLab__InternVL2_5-4B-MPO'
pipe = pipeline(model, backend_config=TurbomindEngineConfig(session_len=8192))

Environment

- cuda 12.4
- python 3.10.15
- torch 2.5.0+cu124
- lmdeploy 0.6.1
- transformers 4.46.1

It is not a bug.
We have no plans to support fp32.
Could you let us know the scenario of applying fp32?

I dont mean to use fp32 but simply run the demo. Even if I set dtype to fp16 I still get the error. With version 0.6.3 it's ok.

[lvhan028]

Oh, sorry for the misunderstanding.
I'll check it.
