How to use dasLOL/Affine-lol with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="dasLOL/Affine-lol", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly

tokenizer = AutoTokenizer.from_pretrained("dasLOL/Affine-lol", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("dasLOL/Affine-lol", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,

	I've uploaded a code repository in the directory /testbed (not in /tmp/inputs). Consider the following PR description:

	<pr_description>
	Bug in posix implementation of django/core/files/locks.py
	Description

	The posix version of locks (the version which supports import fcntl) has a bug. The code attempts to return True to indicate success or failure acquiring a lock, but instead it always returns False. The reason is that cpython fcntl module returns None if successful, and raises an OSError to indicate failure (see https://docs.python.org/3/library/fcntl.html#fcntl.flock).
	Anyone interested in using the non-blocking (i.e. locks.LOCKS_NB) requires a valid return value to know if they have successfully acquired the lock.
	I believe the correct implementation should be the following:
	diff --git a/django/core/files/locks.py b/django/core/files/locks.py
	index c46b00b905..4938347ea7 100644

	## Summary

	I have successfully implemented the fix for the bug in the posix implementation of `django/core/files/locks.py`. The changes made are:

	1. Modified the `lock()` function (lines 109-114): Wrapped the `fcntl.flock()` call in a try-except block that returns `True` on success and `False` when an `OSError` is raised.

	2. Modified the `unlock()` function (lines 116-121): Similarly wrapped the `fcntl.flock()` call in a try-except block that returns `True` on success and `False` when an `OSError` is raised.

	The fix addresses the core issue described in the PR:
	- The original code incorrectly compared the return value of `fcntl.flock()` with 0, but `fcntl.flock()` returns `None` on success and raises an `OSError` on failure
	- This meant the functions always returned `False` (`None == 0` is `False`)
	- The new implementation properly handles the success/failure cases by using try-except blocks
	- This is particularly important for non-blocking locks (`LOCK_NB`) where callers need to know if the lock was successfully acquired

	The changes are minimal and focused, exactly matching the suggested fix in the PR description.<span class="token yellow"><｜end▁of▁sentence｜></span></div>
