CUDA error when deploying model with custom inference
Hi everyone! I am trying to deploy openchat 3.5 (7B) with custom inference, but I’ve been running into CUDA issues. I followed@philschmid’s guide on creating the custom inference:Creating document embeddings with Hugging Face's Transformers & Amazon SageMaker.My “model_fn” function looks like such:def model_fn(model_dir, arg2 = None):
    global device
    device = 'cuda' if torch.cuda.is_available() == True else 'cpu'
    
    tokenizer = AutoTokenizer.from_pretrained(model_dir)
    model = AutoModelForCausalLM.from_pretrained(model_dir, cache_dir="/tmp/model_cache/").to(device)
    model.eval()

    return model, tokenizerand the transform_fn function just calls the tokenizer, model.generate with output_scores = True, and finally I run a softmax function on the relevant logits.I have tried all the way to g5.12xlarge instance but keeps CUDA-ing. According to the logs it does it onAutoModelForCausalLM.from_pretrained. Does anyone have an idea on why this is happening? The model is only 7B it should be able to fit on this instance. I am not sure what other params, or optimizations I need to add and how.Error:An error occurred (ModelError) when calling the InvokeEndpoint operation: Received client error (400) from primary with message "{
