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，实现端到端的感知or决策规划。

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

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。

        "answer": "In the current scene, there are several important objects that need to be considered for the future reasoning and driving decision. These objects include a car driving down the street, a traffic light, a stop sign, a street sign, and a building. The car's position and speed, as well as the traffic light's status, are crucial factors in determining the driver's next move. The stop sign and street sign provide information about the street's name and any potential restrictions or directions. The building in the background adds context to the scene, providing a sense of the surroundings and the environment in which the car is driving."

Reduce speed: Slow down to allow for better visibility and to avoid hydroplaning.3. Use headlights: Turn on headlights to increase visibility for both the driver and other road users.4. Be cautious at intersections: Be extra vigilant at intersections, as visibility may be reduced, and other drivers may not be able to see you clearly.5. Be prepared for sudden stops: Anticipate the need to stop suddenly due to wet roads, and be prepared to react quickly.6. Avoid distractions: Avoid using cell phones, eating, or engaging in other activities that may distract the driver from the road conditions.By following these safety measures, the ego vehicle driver can ensure a safer and more comfortable driving experience in the rainy city street."

The traffic light is an essential element for controlling the flow of traffic and ensuring safety. The street sign provides information about the location and direction of the street, which is crucial for navigation and understanding the context of the scene. The presence of a truck and a bus indicates that the area is likely a commercial or transportation hub, with vehicles carrying goods or passengers. The car is a common sight in urban areas, and its presence indicates that the scene is a typical urban environment with various modes of transportation. The combination of these objects creates a complex and dynamic environment that drivers need to navigate and adapt to."

Maintain a safe distance from other vehicles: The wet road conditions can make it more difficult to stop or maneuver, so it is essential to maintain a safe distance from other vehicles.2. Reduce speed: Driving at a slower speed helps to maintain better control of the vehicle and allows for more time to react to any sudden changes in the road or traffic conditions.3. Use headlights: Turn on the headlights to increase visibility for both the driver and other road users.4. Be cautious of pedestrians: The wet road conditions may make it more difficult for pedestrians to maintain their footing, so the driver should be extra vigilant and slow down when approaching crosswalks or intersections.5. Avoid sudden braking or acceleration: Sudden changes in speed or direction can cause the vehicle to lose traction, leading to skidding or hydroplaning.6.

It is important for the ego vehicle to follow the traffic rules and regulations, such as stopping at the red light when it turns red. Additionally, the ego vehicle should be cautious of other vehicles and pedestrians around it, especially when approaching intersections or making turns. It is essential to maintain a safe distance from other vehicles and pedestrians, and be prepared to stop or slow down if necessary. The ego vehicle should also be aware of any potential hazards or obstacles on the road, such as potholes, debris, or pedestrians crossing the street, and take appropriate actions to avoid accidents or collisions."

Turn right: The ego vehicle could turn right at the intersection, following the traffic light's instructions. This action has a probability of 100% as the vehicle is already at the intersection and following the traffic light's instructions.4. Stop: The ego vehicle could stop at the intersection, waiting for the traffic light to change or for other vehicles to pass.

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

默认4epoch 训练后会在output_path下保存 e1和e4的模型。

 这时候可以重新推理。将原本是llama-adapter-v2的ckpt改成finetune保存后的checkpoint-3.pth。

然后发现结果好很多，主要是对于一些选择题，能正确选出答案，原本zero-shot的llama只是倾向于生成答案，并不会做选择题。说明train=val的这个训练没问题。

六、训练（finetune）

接下来可以用全量数据进行训练，复现baseline。

首先按照上面的数据表格下载nuScenes-DriveLM。笔者这里用的v1_1版本。后续可能还会更新。

下载完drivelm_nus_imgs_train.zip后进行解压unzip，得到一个nuscenes文件夹，mv到challenge/llama_adapter_v2_multimodal7b/data/目录下，得到

然后回到./challenge/目录下，修改extract_data.py，将注释掉的那两行root_path改为上述表格里DriveLM完整的annotation数据:train。save_path是最后保存的json文件名，这样就生成了图-QA对的训练数据。

python extract_data.py

得到类似repo自带的challenge/test.json形式的json文件。接着为了进行LLaMA的finetune，需要转化为LLaMA所需的格式。

还是在./challenge/目录下，修改convert_data.py并执行。

python convert2llama.py

最后一步，将finetune_data_config.yaml里的路径改为train_llama.json。然后执行上面的finetune脚本

# /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

用默认的8卡A100（显存占用34G）跑4epoch  bs4。每个epoch大概十分钟，总共40分钟。

七、验证Eval

验证按照官方文档的challenge中描述的教程，会报错，目前也没找到解决办法，issue里的方法都试了，没用。。无奈放弃eval的复现。
