Quantized using AutoFP8 with this script:

```python
from transformers import AutoTokenizer
import auto_fp8
from auto_fp8 import AutoFP8ForCausalLM, BaseQuantizeConfig

pretrained_model_dir = "ibm-granite/granite-20b-code-base"
quantized_model_dir = "granite-20b-code-base-FP8"

tokenizer = AutoTokenizer.from_pretrained(pretrained_model_dir, use_fast=True)

# use some code to calibrate
import auto_fp8
tmp = auto_fp8.__file__.split('/')[:-1]
tmp.append('quantize.py')
seed_text_file = '/'.join(tmp)

with open(seed_text_file, "r") as f:
    text = f.read()

examples = [text]

examples = tokenizer(examples, return_tensors="pt").to("cuda")

quantize_config = BaseQuantizeConfig(
    quant_method="fp8",
    activation_scheme="static",
    ignore_patterns=["re:.*lm_head"],
)

model = AutoFP8ForCausalLM.from_pretrained(
    pretrained_model_dir, quantize_config=quantize_config
)

model.quantize(examples)
model.save_quantized(quantized_model_dir)
```
