TinyLlama – Getting Began

Right here, on this part, we are going to obtain the quantized model of TinyLlama Chat and run it in Google Colab. Earlier than downloading the mannequin, we have now to obtain and set up the next Python Packages

!CMAKE_ARGS="-DLLAMA_CUBLAS=on" FORCE_CMAKE=1 pip3 set up llama-cpp-python 
!pip3 set up huggingface-hub 

• The CMAKE_ARGS=”-DLLAMA_CUBLAS=on” and FORCE_CMAKE=1, will enable the llama_cpp_python to make the most of the Nvidia GPU out there within the free colab model.
• Then we set up the llama_cpp_python package deal by means of the pip3
• We even obtain the huggingface-hub, with which we will probably be downloading the quantized TinyLlama 1.1B Chat

To check the TinyLlama 1.1B Chat mannequin, we’d like first to obtain the quantized model of it. To obtain it, we are going to run the next code

from huggingface_hub import hf_hub_download

# specifying the mannequin identify
model_name = "TheBloke/TinyLlama-1.1B-Chat-v1.0-GGUF"
# specifying the kind of quantization of the mannequin
model_file = "tinyllama-1.1b-chat-v1.0.Q8_0.gguf"

# obtain the mannequin by specifying the mannequin identify and quantized mannequin identify
model_path = hf_hub_download(model_name, filename=model_file)

Right here, the hugging_face_hub library will care for the method of downloading the quantized mannequin. For this, we import the hf_hub_download that takes within the following parameters:

• model_name: To this variable, we go the mannequin that we want to obtain. Right here we want to obtain the TinyLlama 1.1B Chat GGUF mannequin.
• model_file: Right here we specify the kind of quantized mannequin we need to obtain. Right here we are going to obtain the 8-bit quantized model of the TinyLlama 1.1B Chat.
• Lastly, we go these parameters to the hf_hub_download, which takes in these parameters and downloads the required mannequin. After downloading, it returns the trail the place the mannequin is downloaded.
• This path returned is being saved within the model_path variable.

Now, we are able to load this mannequin by means of the llama_cpp_python library. The code for loading the mannequin will probably be just like the one under.

from llama_cpp import Llama
llm = Llama(
    model_path=model_path,
    n_ctx=512,  # the variety of i/p tokens the mannequin can take
    n_threads=8, # the variety of threads to make use of
    n_gpu_layers=40# what number of layers of the mannequin to dump to the GPU
)

We import the Llama class from the llama_cpp, which takes within the following parameters

• model_path: This variable takes within the path the place our mannequin is saved. We have now obtained the trail from the earlier step, which we will probably be offering right here
• n_ctx: Right here, we give the context size for the mannequin. For now, we’re offering 512 tokens because the context size
• n_threads: Right here we point out the variety of threads for use by the Llama class
• n_gpu_layers: We specify this if we have now a operating GPU, which we do in case of the free colab. To this, we go 40, which suggests that we need to offload the complete mannequin into the GPU and are not looking for any a part of it to run within the system RAM
• Lastly, we create an object from this Llama class and provides it to the variable llm

Operating this code will load the TinyLlama 1.1B Chat quantized mannequin onto the GPU and set the suitable context size. Now, it’s time to carry out some inferences on this mannequin. For this, we work with the under code

output = llm(
  "<|im_start|>usernWho are you?<|im_end|>n<|im_start|>assistantn", # Consumer Immediate
  max_tokens=512,  # Variety of output tokens generated
  cease=["</s>"],   # Token which tells the LLM to cease
)
print(output['choices'][0]['text']) # Mannequin generated textual content

To deduce the mannequin, we go the next parameters to the LLM:

• immediate/chat template: That is the Immediate Template wanted to talk with the mannequin. The above-mentioned template(i.e. <im_end>, <im_start>) is the one which works for the TinyLlama 1.1B Chat mannequin. Within the template, the sentence after the Consumer is the Consumer Immediate, and the era will probably be generated after the Assistant.
• max_tokens: To this variable, we go a worth that defines the utmost variety of tokens a Giant Language Mannequin can output when a Immediate is given. For now, we’re limiting it to 512 tokens.
• cease: To this variable, we go the cease token. The cease token tells the Giant Language Mannequin to cease producing additional tokens. For TinyLlama 1.1B Chat, the cease token is <s>

The generated textual content is saved within the output variable after we run this. The result’s generated in a format just like the OpenAI API name. Therefore, we are able to entry the era by means of the given print assertion, just like how we entry the era from the OpenAI responses. The output generated will be seen under

For a mannequin of this dimension, its generated response is top-notch. That is sudden from a mannequin of this dimension; the grammar and tone look completely wonderful, and there’s no signal of repetition of sentences. Let’s attempt testing the mannequin’s reasoning capabilities

output = llm(
  "<|im_start|>usernIf all college students who examine arduous get good grades, 
  and John received good grades, can we conclude that John studied arduous?
  <|im_end|>n<|im_start|>assistantn",
  max_tokens=512,
  cease=["</s>"],
)


print(output['choices'][0]['text'])

output = llm(
  "<|im_start|>usernHow quick can a snake fly?n<|im_end|>n<|im_start|>assistantn",
  max_tokens=512,
  cease=["</s>"],
)


print(output['choices'][0]['text'])

To date, so good. From the examples we have now seen, the mannequin generates good solutions. However this will not be true in all instances as a result of we solely take a look at it on a restricted variety of questions. Let’s even take a look at the mannequin on its math reasoning capabilities

output = llm(
  "<|im_start|>usernJohn is twice as previous as Sarah, and Sarah is three years 
  older than Mary. If Mary is 10 years previous, how previous is John?n<|im_end|>n<|im_start|>assistantn",
  max_tokens=512,
  cease=["</s>"],
)


print(output['choices'][0]['text'])

output = llm(
  "<|im_start|>usernWhat is the lacking quantity on this sample: 
  1, 4, 9, 16, __, 36?n<|im_end|>n<|im_start|>assistantn",
  max_tokens=512,
  cease=["</s>"],
)


print(output['choices'][0]['text'])

From the examples we have now seen, it’s clear that the TinyLlamaChat performs extraordinarily poorly in answering easy aptitude questions in math. That is anticipated as a result of the mannequin was not pretrained on any maths dataset. The standard of the era will be improved by fine-tuning it on the mathematics dataset
