# Installing Python Packages and Libraries Used In This Book
|
|
|
|
This document provides more information on double-checking your installed Python version and packages. (Please see the [../01_optional-python-setup-preferences](../01_optional-python-setup-preferences) folder for more information on installing Python and Python packages.)
|
|
|
|
I used the following libraries listed [here](https://github.com/rasbt/LLMs-from-scratch/blob/main/requirements.txt) for this book. Newer versions of these libraries are likely compatible as well. However, if you experience any problems with the code, you can try these library versions as a fallback.
|
|
|
|
|
|
|
|
> **Note:**
|
|
> If you you are using `uv` as described in [Option 1: Using uv](../01_optional-python-setup-preferences/README.md), you can replace `pip` via `pip uv` in the commands below. For example, `pip install -r requirements.txt` becomes `uv pip install -r requirements.txt`
|
|
|
|
|
|
|
|
To install these requirements most conveniently, you can use the `requirements.txt` file in the root directory for this code repository and execute the following command:
|
|
|
|
```bash
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
Alternatively, you can install it via the GitHub URL as follows:
|
|
|
|
```bash
|
|
pip install -r https://raw.githubusercontent.com/rasbt/LLMs-from-scratch/main/requirements.txt
|
|
```
|
|
|
|
|
|
Then, after completing the installation, please check if all the packages are installed and are up to date using
|
|
|
|
```bash
|
|
python python_environment_check.py
|
|
```
|

|
|
|
|
It's also recommended to check the versions in JupyterLab by running the `python_environment_check.ipynb` in this directory, which should ideally give you the same results as above.

|
|
|
If you see the following issues, it's likely that your JupyterLab instance is connected to wrong conda environment:

|
|
|
|
In this case, you may want to use `watermark` to check if you opened the JupyterLab instance in the right conda environment using the `--conda` flag:

## Installing PyTorch
|
|
|
|
PyTorch can be installed just like any other Python library or package using pip. For example:
|
|
|
|
```bash
|
|
pip install torch
|
|
```
|
|
|
|
However, since PyTorch is a comprehensive library featuring CPU- and GPU-compatible codes, the installation may require additional settings and explanation (see the *A.1.3 Installing PyTorch in the book for more information*).
|
|
|
|
It's also highly recommended to consult the installation guide menu on the official PyTorch website at [https://pytorch.org](https://pytorch.org).
