This document provides instructions on how to work with Git Large File Storage (LFS) for the `qomnet` project.

Getting Started with Git LFS

Git LFS is a Git extension that improves handling of large files by replacing them with text pointers inside Git, while storing the file content on a remote server.

Downloading single file

Before execution of this script, create an access token with read_api capability and set it as an Environment Variable for GITLAB_ACCESS_TOKEN. Here's how, depending on your operating system: (Gitlab token creation tutorial)

• On Windows:

$env:GITLAB_ACCESS_TOKEN="your_access_token_here"

• On Linux:

export GITLAB_ACCESS_TOKEN="your_access_token_here"

It's also possible to set this variable in PyCharm. Check out this tutorial for guidance.

Once you've set the GITLAB_ACCESS_TOKEN, you can download a file using the following Python function, which includes these parameters:

• host: The domain from which we want to download the dataset
• id: The ID of the desired repository, which can be found on the first page of each repository
• branch_name: The name of the branch where the desired file or data is stored
• file_path: The address of the desired file in the repository

DataLoader().gitlab_download("https://git.arusha.dev", 123, "branch_name", "data/test.gz")

Executing this command initiates the file download process, which is accompanied by a progress bar. The downloaded file is placed in the HOME directory, at: .local/datasets/{project_id}/{branch_name}/{file_path}. You can locate your home directory path based on your operating system:

Operating system	Path
Windows	C:\Users<username>
Linux	/home/
macOS	/Users/

In addition, you might find this tutorial about LFS very helpful.

Installation

To install Git LFS, use the following command:

git lfs install

Clone Repository

To clone repository with only pointer files, use following commands:

• Linux (bash):

GIT_LFS_SKIP_SMUDGE=1 git clone ssh://[e-mail]:9022/majd/datasets/qomnet.git

• Windows:

$env:GIT_LFS_SKIP_SMUDGE="1"
git clone ssh://[e-mail]:9022/majd/datasets/qomnet.git

Tracking Files :

git lfs track "*.psd"
git add .gitattributes

Committing & Pushing Changes :

To commit and push changes, type:

git add file.psd
git commit -m "Add design file"
git push origin main
