|
from transformers import AutoProcessor, AutoModelForCausalLM |

# Load model. |
|

|
processor = AutoProcessor.from_pretrained(MODEL_ID, trust_remote_code=True) |
|
|
|
# Configure the quantization algorithm and scheme. |
|
# In this case, we: |
|
# * quantize the weights to fp8 with per channel via ptq |
|
# * quantize the activations to fp8 with dynamic per token |
|

|
# Apply quantization and save to disk in compressed-tensors format. |
