To support using os.path.basename for parsing the model path, please import the os module. It's good practice to group standard library imports first, followed by third-party imports.

Suggested change
from llmcompressor import model_free_ptq
import os
from llmcompressor import model_free_ptq

MODEL_ID = "zai-org/GLM-4.6"
SAVE_DIR = MODEL_ID.rstrip("/").split("/")[-1] + "-FP8-BLOCK"

For better readability and robustness when parsing the model path, it's recommended to use os.path.basename to extract the model name. This avoids manual string splitting and is generally safer for handling paths.

Suggested change
SAVE_DIR = MODEL_ID.rstrip("/").split("/")[-1] + "-FP8-BLOCK"
SAVE_DIR = os.path.basename(MODEL_ID.rstrip("/")) + "-FP8-BLOCK"


# Apply FP8-Block to the model
# Once quantized, the model is saved
# using compressed-tensors to the SAVE_DIR.
