Learn Generative AI

What is this?

The learnGenAI repository includes several examples of leveraging generative AI. The code is mainly Python using Langchain and connecting to AWS Bedrock.

Getting Started

Setting up the environment

1. We'll first clone the repository

git clone https://github.com/vcollak/learnGenAI

2. Then we'll create a new virtual environment and activate it

On Windows:

python -m venv .venv
.venv\Scripts\activate.bat

Other OSs:

python -m venv .venv
source .venv/bin/activate

3. Install the right python packages

pip install -r requirements.txt

4. If not already, make sure your Amazon AWS account has been configured

Check that you already have the AWS CLI. If not download and install it

aws --version

Configure the AWS cli:

aws configure

You will be asked for your key and a secret:

AWS Access Key ID [None]: YOUR_KEY_HERE
AWS Secret Access Key [None]: YOUR_SECRET_HERE
Default region name [us-east-1]:
Default output format [None]:

If you don't know what your KEY and secret are, you can follow below steps:

1. Access the security page:

2. Click on "Create Access Key"

3. Specify CLI option

4. Optionally set a tag

5. Save your key and secret

6. Test access to your AWS account. You should see a list of S3 buckets you have access to or at minimum not get any errors.

Calling Bedrock services

To make our first call, simply execute below code. Open the 1_hello_claude.py file and take a look at comments to better understand it.

python examples/1_hello_claude.py

This will leverage your AWS credentials and call Bedrock. The code uses the Claude model. You should see something like:

   "completion":" Here is a 97 word summary of the book 'Zero to One' by Peter Thiel:\n\nThe book argues that true innovation comes from doing something completely new, not just iterating on what already exists. It encourages thinking from first principles and developing unique insights. The book advises founders to focus on creating monopolies by starting small but with a large vision. It suggests finding secrets - problems hidden in plain sight that you can solve in a proprietary way. Overall, the book makes the case that going from zero to one - true innovation - creates enormous value, whereas going from one to n - incrementalism - does not.",
