how to run depthai experiments ?

smoothVision

Hello,

to run depthai experiments , what should i do ?

Downloading the whole repository is too much . I tried to download via git only the repository i'm interested in but gives me errors. i have already the depthai folder installed and the examples run fine.

From GPT:

Sparse Checkout with Git

Sparse checkout allows you to clone only specific folders from a repository. This feature can be particularly useful if you need parts of a large repository, such as specific experiments or examples from DepthAI, without downloading everything. Here's how you can use it:

Step 1: Initialize a New Git Repository

First, create a new directory for your repository and initialize it as a Git repository:

mkdir depthai-experiments
cd depthai-experiments
git init

Step 2: Add the Remote Repository

Add the DepthAI repository (or any other repository you're interested in) as a remote source:

git remote add origin https://github.com/luxonis/depthai-experiments.git

Step 3: Enable Sparse Checkout

Enable the sparse checkout feature in your local Git configuration:

git config core.sparseCheckout true

Step 4: Specify the Directories You Want to Checkout

Create a file named sparse-checkout in the .git/info/ directory and add the paths of the directories you're interested in:

echo "examples/your_example_folder/" >> .git/info/sparse-checkout

Replace "examples/your_example_folder/" with the actual path you wish to checkout.

Step 5: Fetch and Checkout

Now, fetch the content from the remote repository and checkout the specified directories:

git fetch --depth=1 origin main
git checkout main

This will fetch only the latest commit (--depth=1 reduces the amount of data downloaded) and checkout the directories you specified in the sparse-checkout file.

Thanks,

the example " collision avoidance " gives errors :

Hi @smoothVision
Where did you find this example?
depthai.Device('', False) has to be called as depthai.Device() or depthai.Device(pipeline).

Thanks,
Jaka

smoothVision

all those lines are just the output in the terminal that i get from running "python3 main.py"

the repository is this one : luxonis/depthai-experimentstree/master/collision-avoidance

Hi @smoothVision
Has to be some old code, for which you need the requirements installed.

0.3.0.0+aeda4a9fdef6edc9f826b7dc354a123d1611a7c6 lord jesus that is old. Please just use the script from the other thread or the SDK.

Thanks,
Jaka
