Expected all tensors to be on the same device, but found at least two devices, cpu and cuda:0!

[d142796]

I tried to follow the information on readme. I created a L4 type of GPU (Based on Ada Lovelace architecture as mentioned by you) via Google Cloud workbench notebook with a lot of storage and ram too. I installed the package by doing this: pip install --pre --extra-index-url https://pypi.nvidia.com optimum-nvidia My python version is 3.10.13

I imported the imports mentioned in the read me: from optimum.nvidia import AutoModelForCausalLM from transformers import AutoTokenizer

I downloaded a regular LLM that even works without optimum. I want to use GPUs for much faster work and wanted to try optimum.

tokenizer = AutoTokenizer.from_pretrained("RuterNorway/Llama-2-7b-chat-norwegian", padding_side="left")

model = AutoModelForCausalLM.from_pretrained(
  "RuterNorway/Llama-2-7b-chat-norwegian",
 use_fp8=True,
 max_prompt_length=1024,
 max_output_length=2048, # Must be at least size of max_prompt_length + max_new_tokens
 max_batch_size=1,
)

model_inputs = tokenizer(["Hva henter Norges hovedstad?"], return_tensors="pt").to("cuda")

generated_ids = model.generate(
    **model_inputs, 
    top_k=40, 
    top_p=0.7, 
    repetition_penalty=10,
)

tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]

After the model has been downloaded I get this: RuntimeError: Expected all tensors to be on the same device, but found at least two devices, cpu and cuda:0! (when checking argument for argument index in method wrapper_CUDA__index_select)
