## Try it
### C#
Code for [use form .Net CSharp on CPU](https://github.com/NethermindEth/Mpt-Instruct-DotNet-S) that runs on Windows, Mac M and Linux
### Python
```python
import torch
import transformers
from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("EleutherAI/gpt-neox-20b")
tokenizer.pad_token = tokenizer.eos_token
device = torch.device("cuda")
model_name = "Nethermind/Mpt-Instruct-DotNet-S"
config = transformers.AutoConfig.from_pretrained(model_name, trust_remote_code=True)
config.init_device = device
config.max_seq_len = 1024
config.attn_config['attn_impl'] = 'torch'
config.use_cache = False
model = transformers.AutoModelForCausalLM.from_pretrained(
model_name,
config=config,
torch_dtype=torch.bfloat16,
trust_remote_code=True,
ignore_mismatched_sizes=True,
# load_in_8bit=True # when low on GPU memory
)
model.eval()

)
def give_answer(instruction="Create a loop over [0, 6, 7 , 77] that prints its contentrs", system="You are an experienced .Net C# developer. Below is an instruction that describes a task. Write a response that completes the request providing detailed explanations with code examples.", ):
question = PROMPT_FOR_GENERATION_FORMAT.format(system=system, instruction=instruction)
input_tokens = tokenizer.encode(question ,return_tensors='pt')
model.generate(input_tokens.to(device), max_new_tokens=min(512, 1024 - input_tokens.shape[1]), do_sample=False, top_k=1, top_p=0.95)
