End-to-end simulation for self-driving cars

Deepdrive

The easiest way to experiment with self-driving AI

Simulator requirements

• Linux or Windows
• Python 3.5+ (Recommend Miniconda for Windows)
• 3GB disk space
• 8GB RAM

Optional - baseline agent requirements

• CUDA capable GPU (tested and developed on 970, 1070, and 1060's)
• Tensorflow 1.1+ See Tensorflow install tips

Install

git clone https://github.com/deepdrive/deepdrive
cd deepdrive

Optional - Activate the Python / virtualenv where your Tensorflow is installed, then

Linux

python install.py

Windows

Make sure the Python you want to use is in your PATH, then

Tip: We highly recommend using Conemu for your Windows terminal

python install.py

Cloud

We've tested on Paperspace's ML-in-a-Box Linux public template which already has Tensorflow installed and just requires

python install.py

If you run into issues, try starting the sim directly as Unreal may need to install some prerequisetes (i.e. DirectX needs to be installed on the Paperspace Parsec Windows box). The default location of the Unreal sim binary is in your user directory under Deepdrive/sim.

Usage

If you're in PyCharm - make sure you disable the SciView in Settings > Tools > Python Scientific > Show Plots in Toolwindow

Run the baseline agent

python main.py --baseline --experiment-name my-baseline-test

Run in-game path follower

python main.py --path-follower --experiment-name my-path-follower-test

Record training data for imitation learning / behavioral cloning

python main.py --record --record-recovery-from-random-actions

Train on recorded data

python main.py --train

Train on the same dataset we used

Grab the dataset

python main.py --train --recording-dir <the-directory-with-the-dataset>

Change cameras to one of the rigs in camera_config.py

python main.py --camera-rigs="three_cam_rig"

Benchmark

Agent	10 lap avg score	Weights	Deepdrive version
Baseline agent (trained with imitation learning)	1691	baseline_agent_weights.zip	2.0
Path follower	*1069	N/A (see 3D spline follower)	2.0

*The baseline agent currently outperforms the path follower it was trained on, likely due to the slower speed the at which the baseline agent drives, resulting in lower lane deviation and g-force penalties. Interestingly, reducing the path follower speed causes it to crash at points where it otherwise loses traction and drifts, so the baseline agent has actually learned a more robust turning function than the original hardcoded path follower it was trained on.

Dataset

100GB (8.2 hours of driving) of camera, depth, steering, throttle, and brake of an 'oracle' path following agent. We rotate between three different cameras: normal, wide, and semi-truck - with random camera intrisic/extrinsic perturbations at the beginning of each episode (lap). This boosted performance on the benchmark by 3x. We also use DAgger to collect course correction data as in previous versions of Deepdrive.

1. Get the AWS CLI
2. Ensure you have 104GB of free space
3. Download our dataset of mixed Windows (Unreal PIE + Unreal packaged) and Linux + variable camera and corrective action recordings (generated with --record)

cd <the-directory-you-want>
aws --no-sign-request --region=us-west-1 s3 sync s3://deepdrive/data/baseline .

tensorboard --logdir <your-unzipped-baseline_tensorflow_train_and_eval>

Frame rate issues on Linux

If you experience low frame rates on Linux, you may need to install NVIDIA’s display drivers including their OpenGL drivers. We recommend installing these with CUDA which bundles the version you will need to run the baseline agent. Also, make sure to plugin your laptop. If CUDA is installed, skip to testing OpenGL.

Tensorflow install tips

• Use the Tensorflow instructions on GitHub for the release you wish to install (not the docs website), i.e. here's the latest - so for v1.6.0, you would use https://github.com/tensorflow/tensorflow/blob/v1.6.0/tensorflow/docs_src/install.
• Make sure to install the CUDA / cuDNN major and minor version the Tensorflow instructions specify. i.e. CUDA 9.0 / cuDNN 7.0. These will likely be older than the latest version NVIDIA offers. You can see all CUDA releases here.
• Use the packaged install, i.e. deb[local] on Ubuntu, referred to in this guide
• If you are feeling dangerous and use the runfile method, be sure to follow NVIDIA’s instructions on how to disable the Nouveau drivers if you're on Ubuntu.

OpenGL

glxinfo | grep OpenGL should return something like:

OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce GTX 980/PCIe/SSE2
OpenGL core profile version string: 4.5.0 NVIDIA 384.90
OpenGL core profile shading language version string: 4.50 NVIDIA
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 4.5.0 NVIDIA 384.90
OpenGL shading language version string: 4.50 NVIDIA
OpenGL context flags: (none)
OpenGL profile mask: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 384.90
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

You may need to disable secure boot in your BIOS in order for NVIDIA’s OpenGL and tools like nvidia-smi to work. This is not Deepdrive specific, but rather a general requirement of Ubuntu’s NVIDIA drivers.
