How to prompt:
import difflib
class NDiff:
def __init__(self, s1, s2):
self.s1 = s1
self.s2 = s2
self.diff = difflib.ndiff(s1.split("\n"), s2.split("\n"))
def __str__(self):
return "\n".join([l for l in self.diff if l[0] != "?"])
def str_colored(self):
import colored
buf = ""
for l in self.diff:
if l[0] == "?":
continue
if l[0] == "-":
buf += colored.stylize(l, colored.fg("red"))
elif l[0] == "+":
buf += colored.stylize(l, colored.fg("green"))
else:
buf += l
buf += "\n"
return buf
def num_removed(self):
return len([l for l in self.diff if l[0] == "-"])
def num_added(self):
return len([l for l in self.diff if l[0] == "+"])
def __repr__(self):
return self.__str__()
def format_prompt(old, new):
diff_header = "<diff>"
instr_header = "<commit_message>"
diff = str(NDiff(old, new))
return f"{diff_header}\n{diff}\n{instr_header}\n"
def gen(old, new, max_new_tokens=200, temperature=0.45, top_p=0.90):
prompt = format_prompt(old, new)
toks = tokenizer.encode(prompt, return_tensors="pt").to(model.device)
outs = model.generate(toks, max_new_tokens=max_new_tokens, do_sample=True, temperature=temperature, top_p=top_p)
return [tokenizer.decode(out[len(toks[0]):], skip_special_tokens=True) for out in outs]
use the "gen" function with the old and new code

This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social
visibility and check back later, or deploy to Inference Endpoints (dedicated)
instead.
