10	04.09.2024	Discussion of subject for the bachelorthesis. Drive the JetRacer in the right lane counterclockwise with the gamepad controller. Limit the speed via Software to a maximum (e. g. 1 m/s). Take a video while driving a lap with MATLAB® using a MATLAB®-script. Load the pretrained NN. Train the pretrained NN with MATLAB® with a MATLAB®-App (GUI) by clicking the desired path in the images. Use classic lane tracking algorithms to teach the NN automatically. Write a PD-contoller that uses the NN to drive in the right lane. Program this in MATLAB® and let it run on the JetRacer-GPU using GPU Coder. Goal: the car should drive autonomously several laps in the right lane as fast as possible.

	Nvcc not Found		- **Edit `.bashrc`:** Since `vim` and `nano` are unavailable, use `vi` if it's installed: ``Code: vi ~/.bashrc ``` - **Clean Up Environment Variables:** Update the `.bashrc` file to remove duplicates and ensure only one set of `PATH` and `LD_LIBRARY_PATH` entries: ```Code: # Add CUDA bin & library paths export PATH=/usr/local/cuda-10.2/bin:$PATH export LD_LIBRARY_PATH=/usr/local/cuda-10.2/lib64:$LD_LIBRARY_PATH ``` - **Save and Exit:** - In `vi`, press `i` to enter insert mode. - Make your changes. - Press `Esc`, then type `:wq` and press `Enter` to save and exit. - **Source `.bashrc`:** Code: source ~/.bashrc
	Install Cudnn		Dokumentieren Sie bitte hier Ihren Fortschritt.
	SDL 1.2 installation		1. **`nvcc`**: Ensure CUDA is correctly installed and its path is added to your `.bashrc` file. 2. **SDL 1.2**: Install the development libraries for SDL 1.2 on your system. You can typically do this with: ```code: sudo apt-get install libsdl1.2-dev ```
	No publick key(update error)	The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A4B469963BF863CC Reading package lists... Done W: GPG error: http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64 InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A4B469963BF863CC E: The repository 'http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64 InRelease' is not signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.	The error message indicates that the GPG key for the NVIDIA CUDA repository is missing. To resolve this, you can manually add the key: 1. **Add the missing key**: ```Code: sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub ``` 2. **Update the package list again**: ```Code: sudo apt-get update ``` This should fix the GPG error and allow you to update the repositories.
