from_pretrained fails to save weights.py and layers.py into cache, therefore fails to find them in cache

[openyk]

• weights.py and layers.py confirmed exist in local model folder, originally saved via cloning (attempt1) and via save_pretrained (attempt2)
• attempting to set custom cache dir as argument or by TRANSFORMERS_CACHE ENV... both ways no effect
• cache folder and other files are saved successfully, so not a permissions issue

Reproduction

from transformers import AutoModelForCausalLM

model = AutoModelForCausalLM.from_pretrained("/path/to/model", trust_remote_code=True, local_files_only=True)

Expected behavior

cache is generated with all relevant model files saved successfully, then loaded from cache for loading the model.
