class_docstr: Parallelformers end-point function
  
  Args:
      model (nn.Module): Huggingface pre-trained transformer model.
      fp16: (bool): whether use FP16 or not.
      num_gpus (int): number of GPU for parallelization.
      master_addr (str): master process address for process communication (default='127.0.0.1')
      master_port (int): master process port for process communication (default=29500)
      backend (str): distributed backend (default='nccl')
      verbose (str): logging current gpu states (one of ['detail', 'simple', None]
      init_method (str): multiprocess initialization method. (It is safe to set `init_method` to `spawn`.)
      daemon (bool): whether make process daemon or not (default=True)
  
  Notes:
      We want to use this object as a simple function rather than a class.
      So we broke the PEP8 rules and set class names that start with a lowercase letter.
  
  Examples:
      >>> # 1. Import Huggingface and Parallelformers modules
      >>> from transformers import AutoModelForCausalLM, AutoTokenizer
      >>> from parallelformers import parallelize
  
      >>> # 2. Create Huggingface model and tokenizer.
      >>> model = AutoModelForCausalLM.from_pretrained("EleutherAI/gpt-neo-2.7B")
      >>> tokenizer = AutoTokenizer.from_pretrained("EleutherAI/gpt-neo-2.7B")
  
      >>> # 3. Parallelize using Parallelformers.
      >>> parallelize(model, num_gpus=4, fp16=True)
  
      >>> # 4. Do inference as usual.
      >>> inputs = tokenizer("Parallelformers is", return_tensors="pt")
      >>> outputs = model.generate(**inputs, num_beams=5, no_repeat_ngram_size=4)
      >>> print(f"Output: {tokenizer.batch_decode(outputs)[0]}")
