It provides low-level access to the C API via the ctypes interface, high-level Python API for text completion, OpenAI-like API, and LangChain compatibility. It supports multiple BLAS backends for faster processing and also supports hardware acceleration.
llama-cpp-python offers a web server that aims to act as a drop-in replacement for the OpenAI API. This allows you to use llama.cpp compatible models with any OpenAI-compatible client (language libraries, services, etc.)
For this project, we are going to use these tools and libraries:
Virtual environments is a good practice to isolate project-specific dependencies and avoid conflicts with system-wide packages. Here’s how to set up a Python environment:
python -m venv env_name
\env_name\Scripts\activate
source env_name/bin/activate
The following command will deactivate the current venv environment:
deactivate
!git clone --recurse-submodules https://github.com/abetlen/llama-cpp-python.git
pip install --upgrade pip
%cd llama-cpp-python
max_tokens_field = Field(
default=16, ge=1, description="The maximum number of tokens to generate."
)
6. Change the default value from 16 to your desired value (e.g., 4096). For example:
max_tokens_field = Field(
default=4096, ge=1, description="The maximum number of tokens to generate."
)
7. Save the changes to the “app.py” file.
Following these steps, you’ll modify the default value for the “max_tokens_field” in the “app.py” file to 4096 or your specified value.
In Google Colab, you typically work in a cloud-based environment with access to NVIDIA GPUs. Therefore, for optimal performance, consider using a BLAS library that is compatible with GPU acceleration. In the case of Google Colab, cuBLAS is a suitable choice, as it is optimized for NVIDIA GPUs, and Colab instances often come with NVIDIA GPU support.

This code snippet demonstrates the creation of agents using the `autogen` library for a scenario where a student seeks guidance from a Coding Mentor and an Algorithm Expert in implementing sorting algorithms in Python.
Here’s a breakdown of the code:
1. Import the autogen module:
import autogen
This imports the necessary functionality from the autogen library.
2. Define agent configurations:
config_list = [
{
"model": "codellama-7b-instruct.Q5_K_M.gguf",
"api_base": "http://127.0.0.1:8000/v1",
"api_type": "open_ai",
"api_key": "NULL", # Placeholder
}
]
This sets up a configuration list specifying details like the model to use, API base URL, type of API, and API key (which is a placeholder in this case).
3. Create agents with different roles and configurations:
coding_mentor = autogen.AssistantAgent(
name="CodingMentor",
llm_config={
"seed": 42,
"config_list": config_list,
"temperature": 0.7,
"request_timeout": 1200,
},
system_message="Coding Mentor here! I
can guide you through implementing
sorting algorithms in Python.",
)
This creates an agent named CodingMentor with a specific configuration for the language model (llm_config), including details like seed, model configuration list, temperature, and request timeout.
algorithm_expert = autogen.AssistantAgent(
name="AlgorithmExpert",
llm_config={
"seed": 42,
"config_list": config_list,
"temperature": 0.7,
"request_timeout": 1200,
},
system_message="Algorithm Expert. I
specialize in algorithms. Let's work
on implementing a sorting algorithm
together.",
)
Similarly, this creates another agent named AlgorithmExpert with similar configurations.
student = autogen.UserProxyAgent(
name="Student",
human_input_mode="ALWAYS",
code_execution_config={"work_dir":"node"},
)
This creates a user proxy agent named Student with the human_input_mode set to “ALWAYS,” indicating that the agent will always expect human input.
4. Initiate a chat between the student and the Coding Mentor:
student.initiate_chat(
coding_mentor,
message="""I'm learning about sorting
algorithms in Python and would like
some guidance on implementation. Can
you help me?""",
)
This initiates a chat between the Student and CodingMentor agents with an initial message from the student.
CodingMentor (to chat_manager):
There are many different sorting algorithms available in Python, but I can give you an overview of a few popular ones:
Bubble sort is a simple sorting algorithm that repeatedly iterates through the array and compares adjacent elements. If two elements are in the wrong order, they swap places until no more swaps are needed. The algorithm repeats this process until the entire array is sorted.
Here’s an example of how to implement bubble sort in Python:
def bubble_sort(arr):
n = len(arr)
for i in range(n-1):
for j in range(0, n-i-1):
if arr[j] > arr[j+1]:
arr[j], arr[j+1] = arr[j+1], arr[j]
return arr
Insertion sort is a simple sorting algorithm that starts at the beginning of the array and compares each element to its predecessor. If the current element is smaller than the predecessor, it moves one position back in the array until it finds a larger element. Then, it inserts the current element into the correct position.
Here’s an example of how to implement insertion sort in Python:
def insertion_sort(arr):
n = len(arr)
for i in range(1, n):
key = arr[i]
j = i-1
while j >= 0 and arr[j] > key:
arr[j+1] = arr[j]
j -= 1
arr[j+1] = key
return arr
Selection sort is a simple sorting algorithm that works by selecting the smallest element from the unsorted part of the array and placing it at the beginning of the sorted part. It then repeats this process for the remaining elements in the unsorted part until the array is sorted.
Here’s an example of how to implement selection sort in Python:
def selection_sort(arr):
n = len(arr)
for i in range(n-1):
min_idx = i
for j in range(i+1, n):
if arr[j] < arr[min_idx]:
min_idx = j
arr[i], arr[min_idx] = arr[min_idx], arr[i]
return arr
Merge sort is a more efficient sorting algorithm that works by dividing the array into two halves, sorting each half recursively, and then merging the two sorted halves. It has an average time complexity of O(n log n).
Here’s an example of how to implement merge sort in Python:
def merge_sort(arr):
if len(arr) <= 1:
return arr
mid = len(arr) // 2
left = merge_sort(arr[:mid])
right = merge_sort(arr[mid:])
return merge(left, right)
def merge(left, right):
result = []
while len(left) > 0 and len(right) > 0:
if left[0] <= right[0]:
result.append(left.pop(0))
else:
result.append(right.pop(0))
if len(left) > 0:
result += left
if len(right) > 0:
result += right
return result
Quick sort is a more efficient sorting algorithm that selects a pivot element from the unsorted part of the array, partitions the array around that pivot, and then recursively sort the two partitions. It has an average time complexity of O(n log n).
Here’s an example of how to implement quick sort in Python:
def quick_sort(arr):
if len(arr) <= 1:
return arr
pivot = arr[0]
less = [x for x in arr[1:] if x <= pivot]
greater = [x for x in arr[1:] if x > pivot]
return quick_sort(less) + [pivot] + quick_sort(greater)
I hope this helps! Let me know if you have any questions or need further clarification on these algorithms.

CodingMentor (to chat_manager):
Sure, here are some real-world use cases for each sorting algorithm
Bubble sort is often used as a simple example to explain the basic concept of a sorting algorithm. It’s easy to understand and implement but inefficient for large datasets. One real-world use case for bubble sort is in a school project management system where you must sort projects based on their due dates or priority levels.
Insertion sort is a simple sorting algorithm that’s often used as a stepping stone for more advanced algorithms like quicksort and mergesort. It has a time complexity of O(n^2), which makes it less efficient than some other sorting algorithms for large datasets.One real-world use case for insertion sort is in a social media platform where you need to sort users based on their follower counts or engagement levels.
Selection sort is another simple sorting algorithm that’s easy to understand and implement, but it’s not very efficient for large datasets. It has a time complexity of O(n^2), which makes it less efficient than some other sorting algorithms.One real-world use case for selection sort is in a library management system where you need to sort books based on their titles or authors.
Merge sort is a more efficient sorting algorithm with an average time complexity of O(n log n). It’s commonly used in many real-world applications, such as sorting large datasets, searching for specific data, and performing other operations that require efficient sorting. One real-world use case for merge sort is in a search engine where you need to sort web pages based on their relevance or popularity.
Quick sort is another efficient sorting algorithm with an average time complexity of O(n log n). It’s commonly used in many real-world applications, such as sorting large datasets, searching for specific data, and performing other operations that require efficient sorting. One real-world use case for quick sort is in a social media platform where you need to sort users based on their follower counts or engagement levels.
In general, the choice of which sorting algorithm to use depends on the size of the dataset, the type of data being sorted, and the application’s specific requirements.
Thank you for providing some real-world use cases for each sorting algorithm. This helps to illustrate the different applications and scenarios in which each algorithm can be used.
Here are some additional thoughts on each of these algorithms:

This AutoGen use case demonstrates the automation of generating a stock price chart for specified companies Amazon(AMZN), Apple(AAPL), and Intel Corporation ( INTC) Year-to-Date (YTD). The assistant agent utilizes the yfinance, matplotlib, and pandas packages to fetch stock prices and create a visually appealing chart. The user proxy agent initiates the conversation with a clear task description, and the assistant responds by generating Python code to accomplish the requested task. The resulting chart is saved as “stock_price_ytd.png.” This use case showcases the seamless integration of AutoGen with external libraries for data retrieval, visualization, and code execution in a real-world scenario.

assistant (to user_proxy):
To plot the year-to-date (YTD) stock price changes of Amazon (AMZN), Apple (AAPL), and Intel (INTC) using the yfinance, matplotlib, and pandas packages in Python, you can use the following code:
```python
import yfinance as yf
import matplotlib.pyplot as plt
import pandas as pd
# Get the stock prices for AMZN, AAPL, and INTC
amzn = yf.download('AMZN', start='2018-01-01')['Close']
aapl = yf.download('AAPL', start='2018-01-01')['Close']
intc = yf.download('INTC', start='2018-01-01')['Close']
# Convert the stock prices to a pandas DataFrame
data = pd.DataFrame({'AMZN': amzn, 'AAPL': aapl, 'INTC': intc})
# Plot the YTD price changes using matplotlib
plt.plot(data.index, data['AMZN'], label='AMZN')
plt.plot(data.index, data['AAPL'], label='AAPL')
plt.plot(data.index, data['INTC'], label='INTC')
plt.legend()
plt.xlabel('Date')
plt.ylabel('Price Change (%)')
plt.title('YTD Stock Price Changes')
plt.savefig('stock_price_ytd.png', dpi=300)
```
This code first imports the necessary packages and then downloads the stock prices for AMZN, AAPL, and INTC using the yfinance package. The downloaded data is then converted to a pandas DataFrame and plotted using matplotlib. The YTD price changes are shown as a line graph with the date on the x-axis and the price change in percentage on the y-axis. The legend is displayed to indicate which stock is being represented by each line. Finally, the plot is saved as an image file called `stock_price_ytd.png` using the `savefig()` method of matplotlib.
Note that this code assumes that you have already installed the necessary packages and have a working internet connection. Also, the data used in this example is for demonstration purposes only and may not reflect the actual price changes of these stocks over time.

Let’s display the generated figure.
from IPython.display import Image
Image(filename='coding/stock_price_ytd.png')
Note: After running this code successfully, you can find the “stock_price_ytd.png” file in the same directory where your Python script or Jupyter Notebook is located. This is the default behavior of the savefig function from the matplotlib library. If you want to save the image in a different directory, you can provide the full path in the savefig function.
Previously, the code was executed in a distinct process, preventing the immediate display of the plot within the notebook. To address this, we can modify the code execution environment to use IPython.
Certainly! Below, we illustrate the process of extending the UserProxyAgent to incorporate a different code execution environment, specifically IPython.
1. Import Packages
from typing import Dict, Union
from IPython import get_ipython
import autogen
2. Class Definition:
class IPythonUserProxyAgent(autogen.UserProxyAgent):
This class inherits from autogen.UserProxyAgent, suggesting it is an extension or customization of a base class.
3. generate_init_message:
def generate_init_message(self, *args, **kwargs) -> Union[str, Dict]:
return super().generate_init_message(*args, **kwargs) + """
If you suggest code, the code will be executed in IPython."""
This method generates an initial message to send to the assistant agent. It appends a note indicating that code suggestions will be executed in the IPython environment.
4.run_code:
def run_code(self, code, **kwargs):
result = self._ipython.run_cell("%%capture --no-display cap\n" + code)
log = self._ipython.ev("cap.stdout")
log += self._ipython.ev("cap.stderr")
if result.result is not None:
log += str(result.result)
exitcode = 0 if result.success else 1
if result.error_before_exec is not None:
log += f"\n{result.error_before_exec}"
exitcode = 1
if result.error_in_exec is not None:
log += f"\n{result.error_in_exec}"
exitcode = 1
return exitcode, log, None
This method runs the provided code within the IPython environment. It uses the run_cell method to execute the code and capture the output. The method constructs a log containing standard output, standard error, and additional information about the execution.
import autogen
ipy_user = IPythonUserProxyAgent(

)
This snippet creates an instance of IPythonUserProxyAgent and initiates a chat with the assistant, providing a message that includes a task description plot of a stacked area chart visualizing the yearly high and low prices of Apple (AAPL), Google (GOOGL), Amazon (AMZN), and Microsoft (MSFT) use yfinance,matplotlib, pandas packages.
plot a stacked area chart visualizing the yearly high and low prices of
Apple (AAPL), Google (GOOGL), Amazon (AMZN), and Microsoft (MSFT)
use yfinance,matplotlib,pandas packages
If you suggest a code, the code will be executed in IPython.
Here is a suggested solution using the `yfinance` and `matplotlib` libraries:
```
import yfinance as yf
import matplotlib.pyplot as plt
import pandas as pd
# Get historical data for the four stocks
stocks = ['AAPL', 'GOOGL', 'AMZN', 'MSFT']
prices = yf.download(stocks, start='2010-01-01', end='2022-05-31')['Close']
# Convert to a DataFrame and drop missing values
df = pd.DataFrame(prices)
df = df.dropna()
# Plot the stacked area chart
plt.style.use('ggplot')
fig, ax = plt.subplots(figsize=(12, 6))
ax.stackplot(df.index, df['AAPL'], df['GOOGL'], df['AMZN'], df['MSFT'], labels=stocks)
ax.set_xlabel('Date')
ax.set_ylabel('Price ($)')
ax.legend()
plt.show()
```
This code uses the `yfinance` library to download historical price data for the four stocks from January 1, 2010, to May 31, 2022. It then converts the prices into a DataFrame and drops any missing values (e.g., if a stock was not traded on a particular day). Finally, it uses `matplotlib` to create a stacked area chart showing each stock’s yearly high and low prices. The resulting plot includes a legend with the names of the four stocks.
Note that this is just one possible solution to the problem, and there may be other ways to approach the task depending on your specific needs and requirements.
