Reproduction

volume=$PWD/data # share a volume with the Docker container to avoid downloading weights every run

docker run --gpus all --shm-size 1g -p 8080:80 -v $volume:/data ghcr.io/huggingface/text-generation-inference:latest --model-id $model --num-shard $num_shard

Expected behavior

I gave the seed value and used the do_sample flag, all 10 should receive the same results. but I received several results.

when i use 0.6.0 and --max-batch-size 1 result is

10 Deep Learning is defined as a theory that explores the same idea in different ways, so various difficulties exist in it because some can be solved, others

@OlivierDehaene Hi Oliver I tested it on a CPU batch and the result was the same, so I changed the dtype to float32 when using GPU and the batch worked.

[jshin49]

How did you change the dtype to float32?

Hmmm what about the TGI with version 1.0.0+? Seems some flags are already sunsetted
