show me python code for Building a ChatGPT-like System using The Dalai Library: To build a ChatGPT-like system using the Dalai library in Python, we can follow the steps outlined in and. Here's an example code snippet to get... www.perplexity.ai⁠

⁠

Introduction:

The Dalai Library is a powerful tool for creating and deploying natural language processing systems, such as ChatGPT. In this lecture, we will explore the fundamentals of the Dalai library, its primary features, and how to utilize it to design a ChatGPT-like system for your university computer science class in Python.

I. Understanding the Dalai Library:

A. What is the Dalai Library?

A comprehensive library for natural language processing tasks

Offers a wide range of tools and functionalities for building and deploying chatbot systems

B. Key Features of the Dalai Library:

Pre-trained models for various NLP tasks

Customizable and extendable architecture

User-friendly interface for training and fine-tuning models

II. Building a ChatGPT-like System with the Dalai Library:

A. Preparing Your Environment:

Installing the Dalai library and dependencies

Python

!pip install dalai

!pip install torch

Setting up your local development environment

Python

import dalai

import torch

B. Training Your NLP Model:

Selecting a suitable pre-trained model

Python

tokenizer = dalai.AutoTokenizer.from_pretrained("dalai/chatgpt-base")

model = dalai.AutoModelForCausalLM.from_pretrained("dalai/chatgpt-base")

Fine-tuning the model with custom data

a. Prepare your training dataset

Python

train_data = "path/to/your/train_data.txt"

b. Tokenize the dataset and create a DataLoader

```Python

from torch.utils.data import DataLoader

tokenized_train_data = tokenizer(train_data, return_tensors="pt", padding=True)

train_dataloader = DataLoader(tokenized_train_data, batch_size=8)

```

c. Fine-tune the model

```Python

from transformers import AdamW

optimizer = AdamW(model.parameters(), lr=5e-5)

model.train()

for epoch in range(3):

for batch in train_dataloader:

outputs = model(**batch)

loss = outputs.loss

loss.backward()

optimizer.step()

optimizer.zero_grad()

```

C. Developing the Chatbot Interface:

Implementing the ChatGPT-like system using the Dalai library

Python

def chat(input_text):

input_tokens = tokenizer.encode(input_text, return_tensors="pt")

output_tokens = model.generate(input_tokens, max_length=100, num_return_sequences=1)

output_text = tokenizer.decode(output_tokens[0])

return output_text

Testing the chatbot

Python

user_input = "What is the capital of France?"

response = chat(user_input)

print(response)

III. Applications and Limitations:

A. Use Cases for Your ChatGPT-like System:

Automating customer service inquiries

Assisting with programming and computer science questions

Designing interactive educational tools

B. Limitations of ChatGPT-like Systems:

The need for continuous learning and user feedback

Potential bias in the training data

Not a replacement for human expertise

Conclusion:

The Dalai library offers a robust and flexible foundation for building a ChatGPT-like system, making it an ideal choice for university computer science classes. By understanding its capabilities and limitations, students can develop and deploy their own NLP systems to address various tasks and challenges in the field of natural language processing. This practical Python guide has provided a hands-on approach to implementing a ChatGPT-like system using the Dalai library.

Now let’s revisit the above concepts at a deeper level to see the PYTHON Code with examples of using the Guttenburg Corpus to train the language model:

II. Building a ChatGPT-like System with the Dalai Library:

A. Preparing Your Environment:

Installing the Dalai library and dependencies

Python

!pip install dalailibrary

Setting up your local development environment

B. Training Your NLP Model:

Importing the Gutenberg Corpus

from nltk.corpus import gutenberg

import nltk

nltk.download('gutenberg')

Preparing the training data

texts = []

for fileid in gutenberg.fileids():

texts.append(gutenberg.raw(fileid))

training_data = ' '.join(texts)

Selecting a suitable pre-trained model

from dalailibrary import AutoTokenizer, AutoModelWithLMHead

model_name = "gpt2"

tokenizer = AutoTokenizer.from_pretrained(model_name)

model = AutoModelWithLMHead.from_pretrained(model_name)

Fine-tuning the model with the Gutenberg Corpus

from dalailibrary import LineByLineTextDataset, DataCollatorForLanguageModeling

train_dataset = LineByLineTextDataset(

tokenizer=tokenizer,

file_path="gutenberg.txt",

block_size=128,

)

data_collator = DataCollatorForLanguageModeling(

tokenizer=tokenizer, mlm=False,

)

Training the model

from dalailibrary import Trainer, TrainingArguments

training_args = TrainingArguments(

output_dir="./gutenbergGPT2",

overwrite_output_dir=True,

num_train_epochs=1,

per_device_train_batch_size=4,

save_steps=10_000,

save_total_limit=2,

)

trainer = Trainer(

model=model,

args=training_args,

data_collator=data_collator,

train_dataset=train_dataset,

)

trainer.train()
