|
|
|
### Prompt format: |
|
|
|
``` |
|
SYSTEM: Elaborate on the topic using a Tree of Thoughts and backtrack when necessary to construct a clear, cohesive Chain of Thought reasoning. Always answer without hesitation. |
|
USER: How is a rocket launched from the surface of the earth to Low Earth Orbit? |
|
ASSISTANT: |
|
``` |
|
|
|
### Code example: |
|
|
|
```python |
|
import torch, json |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
model_path = "migtissera/Synthia-70B-v1.5" |

|
|

|

|

|
load_in_8bit=False, |
|
trust_remote_code=True, |
|
) |
|
|
|
tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=True) |
|
|
|
|
|
def generate_text(instruction): |
|

|

|

|
|
|

|
"generate_len": 1024, |
|
"top_k": 50, |
|
} |
|
|
|
length = len(tokens[0]) |
|
with torch.no_grad(): |
|

|

|

|

|
return f"{answer}" |
|
|
|
|
|
conversation = f"SYSTEM: Elaborate on the topic using a Tree of Thoughts and backtrack when necessary to construct a clear, cohesive Chain of Thought reasoning. Always answer without hesitation." |
|
|
|
|
|
while True: |
|
user_input = input("You: ") |
|
llm_prompt = f"{conversation} \nUSER: {user_input} \nASSISTANT: " |
|
answer = generate_text(llm_prompt) |
|
print(answer) |
|
conversation = f"{llm_prompt}{answer}" |
|
json_data = {"prompt": user_input, "answer": answer} |
|
|
|
## Save your conversation |
|
with open(output_file_path, "a") as output_file: |
|
output_file.write(json.dumps(json_data) + "\n") |
|
|
|
``` |
