setting `--gpu_device ` is not working for mutiple GPUs

I have a server with 8 * A100 40G GPUs, and I try to run Alphafold3 with docker or bash, but nomatter how I set `--gpu_device`, only the first GPU is used.

Here is some test and outputs

Here is my test.

```
input_data="/home/menghw/data2/AF3_test_json/"
output_data="/home/menghw/data2/02.AF3_output/"
model_dir="/home/menghw/07.AF3_local_test/alphafold3/weights/"
database_dir="/home/menghw/07.AF3_local_test/database/"
docker run -it \
--volume $input_data:/root/af_input \
--volume $output_data:/root/af_output \
--volume $model_dir:/root/models \
--volume $database_dir:/root/public_databases \
--gpus 8 \
alphafold3 \
python run_alphafold.py \
--json_path=/root/af_input/06.test_multi_GPU8.json \
--model_dir=/root/models \
--output_dir=/root/af_output \
--gpu_device=7
```

Here is running log

```
use the model parameters.

Although, it is look like running well, only the first GPU is taken!
