[BUG] Unable to Use quantization_setting for Customizing MoQ in DeepSpeed Inference

[cyx96]

Describe the bug
Unable to customize MoQ using quantization_setting with DeepSpeed inference.

To Reproduce
Follow the example from the DeepSpeed inference tutorial on datatypes and quantized models.

Below is the full script to reproduce the issue:

import torch
from transformers import T5Tokenizer, T5ForConditionalGeneration
import deepspeed

# Load T5 model and tokenizer
model_name = "t5-small"  # You can change this to other T5 models like 't5-base' or 't5-large'
tokenizer = T5Tokenizer.from_pretrained(model_name)
model = T5ForConditionalGeneration.from_pretrained(model_name)

# Define quantization settings
quantize_groups = 8  # Example setting; adjust as needed
mlp_extra_grouping = True  # Example setting; adjust as needed

# Initialize DeepSpeed inference with quantization
model = deepspeed.init_inference(
    model=model,
    mp_size=1,  # Model parallel size (1 if no model parallelism is used)
    quantization_setting=(quantize_groups, mlp_extra_grouping)
)

# Tokenize input text
input_text = "Translate English to French: Hello, how are you?"
inputs = tokenizer(input_text, return_tensors="pt")

# Perform inference
outputs = model.generate(**inputs)
output_text = tokenizer.decode(outputs[0], skip_special_tokens=True)

# Print the result
print("Input:", input_text)
print("Output:", output_text)

Expected behavior
The script should take the input in English and produce the French translation using the T5 model. However, an error is raised:

pydantic_core._pydantic_core.ValidationError: 1 validation error for DeepSpeedInferenceConfig

You are using the default legacy behaviour of the <class 'transformers.models.t5.tokenization_t5.T5Tokenizer'>. This is expected, and simply means that the `legacy` (previous) behavior will be used so nothing changes for you. If you want to use the new behaviour, set `legacy=False`. This should only be set if you understand what it means, and thoroughly read the reason why this was added as explained in https://github.com/huggingface/transformers/pull/24565
