Deep Learning examples used for teaching within the Department of Computer Science at Durham University (UK) by Dr. Amir Atapour-Abarghouei.

The material is presented as part of the "Deep Learning" lecture series at Durham University.

All material here has been tested with PyTorch 1.12 and Python 3.9.

• You may download each file as needed.
• You can also download the entire repository as follows:

git clone https://github.com/atapour/dl-pytorch
cd dl-pytorch

In this repository, you will find directories that contain examples that demonstrate different features of PyTorch Programming and Deep Learning in general. In the directories, you can find:

• .py file - python code for the example
• .ipynb file - Jupyter notebook for the example

• You can simply run each Python file by running:

python <example file name>.py

• You can run the notebooks using Jupyter.
• Note that it is recommended that you run the scripts (especially those that train a neural network) on GPU hardware. If you do not have access to a GPU locally, you can use free services like Google Colaboratory using the following steps:

• Navigate to - https://colab.research.google.com
• Sign in with your Google account.

• Select File -> Upload Notebook... -> Github
• Paste the URL of the notebook on GitHub. For instance, for the notebook in this repository that covers PyTorch Tensors, you can use this URL: https://github.com/atapour/dl-pytorch/blob/main/1.Tensors/1.PyTorch_Programming_Tensors.ipynb. You can change the URL depending on the notebook you would like to run.

• Select File -> Upload Notebook...
• Drag and drop or browse to select the notebook you wish to use (e.g., 1.Tensors/PyTorch_Programming_Tensors.ipynb).

• If a program is specifically written to use a GPU, make sure you enable the use of a GPU in Google Colab.

• Select Runtime -> Change runtime type -> GPU

• Alternatively, you can change the first code cell of the notebook to use a CPU to run the code by including device = torch.device('cpu').

In this repository, you can find the following examples:
