If you’re utilizing your individual function, add the next belief relationships as defined when creating the service function for mannequin import:

As soon as the mannequin is imported, watch for the mannequin inference to be prepared earlier than chatting with the mannequin through the playground or API. Within the following instance, we add Python It prompts the mannequin to output Python code immediately and lists the gadgets in an S3 bucket. Remember to make use of the suitable chat template and enter the immediate within the required format. For instance, you should use the code under to get a chat template appropriate for any mannequin that hugs your face.

from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-Coder-7B-Instruct")

# As an alternative of utilizing mannequin.chat(), we immediately use mannequin.generate()
# However it is advisable use tokenizer.apply_chat_template() to format your inputs as proven under
immediate = "Write pattern boto3 python code to record information in a bucket saved within the variable `my_bucket`"
messages = [
    {"role": "system", "content": "You are a helpful coding assistant."},
    {"role": "user", "content": prompt}
]
textual content = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

Watch out when utilizing invoke_model The API requires that the imported mannequin makes use of the complete Amazon useful resource title (ARN). Yow will discover the mannequin ARN within the bedrock console by going to the imported mannequin part and viewing the mannequin particulars web page, as proven within the following picture.

When you’re able to infer the mannequin, you’ll be able to name the mannequin utilizing the bedrock console or the chat playground within the API.
