NumPy, Pandas & LangChain are powerful open-source Python libraries widely used in data science, machine learning, and AI application development. Together, they provide robust tools for numerical computation, data manipulation, and advanced language model integration.

Features of NumPy, Pandas & LangChain:

• NumPy: Provides high-performance multi-dimensional array operations and mathematical functions for numerical computing.
• Pandas: Offers data structures like DataFrames and Series for efficient data cleaning, manipulation, and analysis.
• LangChain: Enables building powerful LLM (Large Language Model) applications by connecting models (like OpenAI or Falcon) with structured reasoning and data workflows.
• All libraries are open-source and well-maintained by the Python community.
• Compatible with machine learning and AI frameworks such as Scikit-learn, PyTorch, and Hugging Face Transformers.
• Highly efficient and suitable for both research and production environments.

To check the installed version of NumPy, Pandas, and LangChain (when installed in a virtual environment on Ubuntu), use the following commands:

$ sudo su
$ sudo apt update
$ cd /opt/langchain-env
$ source venv/bin/activate
$ python -c "import numpy; print('NumPy version:', numpy.__version__)"
$ python -c "import pandas; print('Pandas version:', pandas.__version__)"
$ python -c "import langchain; print('LangChain version:', langchain.__version__)"
