DriveLM的baseline复现

DriveLM是一篇很有意思的工作，把自动驾驶跟MLLM结合到一起了，实现端到端的决策。

Repo：https://github.com/OpenDriveLab/DriveLM

该工作是基于nuScenes数据集做的，官方paper里给出了数据的具体构建方式，感兴趣的可以移步https://arxiv.org/abs/2312.14150

官方也给出了榜单，本文章主要复现该榜单的baseline，从而熟悉一下相关工作。

首先下载Repo，然后cd到challenge/目录，相关的baseline训练评估测试都在这个目录下进行。

官方给出的baseline以 LLaMA-7B和 llama-adapter v2 实现。

一、环境配置

按照官方文档配置，我没有进行修改，用的CUDA11.8+A100显卡

二、权重准备

准备好LLaMA-7B（注意不是LLaMA-2-7B）的相关权重文件，可以通过https://docs.google.com/forms/d/e/1FAIpQLSfqNECQnMkycAp2jP4Z9TFX0cGR4uf7b_fBxjY_OjhJILlKGA/viewform?usp=send_form申请得到下载的url，因为我申请没被通过（不知道为啥。。用了学校的edu邮箱），因此去hf上找了一个别人上传的权重仓库https://huggingface.co/nyanko7/LLaMA-7B/tree/main。

下载在本地后按照下图的结构布置整个文件目录

此外，从https://github.com/OpenGVLab/LLaMA-Adapter/releases/tag/v.2.0.0下llama_adapter_v2的相关权重（以下所有pre-trained checkpoints或者ckpt都指这个llama_adapter_v2而非LLaMA-7B的相关权重），目前有三个权重文件，选哪个都差不多。

三、数据准备（demo）

readme里的数据写的有点混乱，我整理了关于原始仓库附带的数据/json文件。在不下载任何额外数据和操作的情况下，利用原始仓库自带的test_llama.json就可以跑一个infer的demo

目录	备注
challenge/data/train_sample.json	训练数据的demo，对应该json相关的图片等数据在challenge/llama_adapter_v2_multimodal7b/data/nuscenes/samples
challenge/test_llama.json	用于baseline（llama-7B）的train和infer的输入demo数据
challenge/output.json	用于baseline（llama-7B）的infer输出的demo数据
https://huggingface.co/datasets/OpenDriveLab/DriveLM/blob/main/v1_1_train_nus.json	DriveLM完整的annotation数据:train
https://huggingface.co/datasets/OpenDriveLab/DriveLM/blob/main/v1_1_val_nus_q_only.json	DriveLM完整的annotation数据:val
https://huggingface.co/datasets/OpenDriveLab/DriveLM/blob/main/drivelm_nus_imgs_train.zip& https://huggingface.co/datasets/OpenDriveLab/DriveLM/blob/main/drivelm_nus_imgs_val.zip	DriveLM完整的数据:train和val

四、推理demo

准备完毕后，通过下方一行代码实现zero-shot的推理infer demo

# /path/to/llama_model_weights and /path/to/pre-trained/checkpoint.pth need to be modified by your path
# num_processes is the number of the gpu you will use to infer the data.
# make sure you are under ./challenge/llama_adapter_v2_multimodal7b
## 注意这里的checkpoint是任意一个llama-adapter-v2的权重
## --data对应的是原始仓库的 test_llama.json路径 --output是保存的推理答案路径
## --num_processes是GPU数目, 单卡的话改成1
python demo.py --llama_dir /path/to/llama_model_weights --checkpoint /path/to/pre-trained/checkpoint.pth --data ../test_llama.json  --output ../output.json --batch_size 4 --num_processes 8

得到下方对应test_llama.json中17段数据推理的答案，如果answer是什么\n \n乱七八糟的，大概率是权重不对，代码和数据没问题。我这边用的是llama-adapter-v2的权重中的7fa55208379faf2dd862565284101b0e4a2a72114d6490a95e432cf9d9b6c813_BIAS-7B.pth

实测这个推理结果跟官方给的output.json答案一致，如果用其他ckpt，答案会不同，但是不同的答案也算合理，不会出现乱码。

Failing to yield to the pedestrian crossing the street: If the ego vehicle is not paying attention to the pedestrian crossing the street, it may not notice the pedestrian in time and could collide with them.2. Failing to stop at the stop sign: If the ego vehicle fails to stop at the stop sign, it may continue driving without checking for oncoming traffic or pedestrians, increasing the risk of a collision.3. Failing to yield to the traffic light: If the ego vehicle fails to yield to the traffic light, it may continue driving without checking for oncoming traffic or pedestrians, increasing the risk of a collision.4. Failing to maintain a safe distance from the vehicle in front: If the ego vehicle is too close to the vehicle in front, it may not have enough time to react to sudden changes in the vehicle's speed or direction, increasing the risk of a collision.5. Driving too fast for the road conditions: If the ego vehicle is driving too"},{"id": "54cdaaae372d421fa4734d66f51a8c48_0dd14c14cea14dc1b0c0c9b0c9c7c4c3_5","question": "<image>\nIn this scenario, what are safe actions to take for the ego vehicle?","answer": "In the image, the ego vehicle is driving down a street with a sidewalk on the side. To ensure safety, the driver should:1. Maintain a safe distance from the sidewalk, especially if pedestrians are present.2. Be cautious of any pedestrians or cyclists who may be crossing the street or using the sidewalk.3. Obey traffic signals and signs, as well as any posted speed limits.4. Be aware of any potential hazards or obstacles on the road, such as potholes, debris, or other vehicles.5. Be prepared to stop or slow down if necessary to avoid collisions or accidents.By following these safety measures, the driver can help ensure the safety of themselves, their passengers, and other road users."},{"id": "54cdaaae372d421fa4734d66f51a8c48_0dd14c14cea14dc1b0c0c9b0c9c7c4c3_6","question": "<image>\nPredict the behavior of the ego vehicle.

五、训练（finetune）demo

训练需要修改finetune_data_config.yaml中关于训练数据的路径

demo可以直接利用test_llama.json进行训练。如果要复现baseline需要下载nuScenes并且转化出train_llama.json，后续会提及，这里先跑通代码。

同理，ckpts是adapter的，output path是work_dirs的路径，随便填，会自动创建，命令执行后会在ouput_path下生成logs并将终端的信息打印进去（感觉是商汤的老传统了，跑脚本都不喜欢在终端看，喜欢重定向到log文件去看）。同推理，单卡需要修改--nproc_per_node=1

# /path/to/llama_model_weights, /path/to/pre-trained/checkpoint.pth and /output/path need to be modified by your path
# make sure you are under ./challenge/llama_adapter_v2_multimodal7b
.exps/finetune.sh \
/path/to/llama_model_weights /path/to/pre-trained/checkpoint.pth \
finetune_data_config.yaml /output/path

我这边在终端打印出了log
