#case1: HybridAdam
from lightning.pytorch import trainer, LightningModule
from colossalai.nn.optimizer import HybridAdam
class MyDiffuser(LightningModule):
...
def configure_sharded_model(self) -> None:
# create your model here
self.model = construct_diffuser_model(...)
...
def configure_optimizers(self):
# use the specified optimizer
optimizer = HybridAdam(self.model.parameters(), self.lr)
...
model = MyDiffuser()
trainer = Trainer(accelerator="gpu", devices=1, precision=16, strategy="colossalai")
trainer.fit(model)
#case2: ColossalAIStrategy显存优化
from lightning.pytorch import trainer, LightningModule
from lightning.pytorch.strategies import ColossalAIStrategy
Mystrategy = ColossalAIStrategy(use_chunk=True, enable_distributed_storage=True, placement_policy=auto)
trainer = Trainer(accelerator="gpu", devices=4, precision=16, strategy=Mystrategy)
trainer.fit(model)

finetune：低成本，通过较少资源短时间训练出可以生成自己风格的模型
基于 HuggingFace 上开源的 Stable Diffusion 模型权重进行微调
步骤：- 修改 Dataloader 载入微调数据集
- 读取预训练权重
- 简单修改参数配置 yaml 文件并运行训练脚本
python main.py --logdir /your_log_dir -t -b config/train_colossalai.yaml
model:
target: ldm.models.diffusion.ddpm.LatentDiffusion
params:
your_sub_module_config:
target: your.model.import.path
params:
from_pretrained: 'your_file_path/unet/diffusion_pytorch_model.bin'
...
lightning:
trainer:
strategy:
target: pytorch_lightning.strategies.ColossalAIStrategy
params:
...
-
inference：支持原生 Stable Diffusion 推理管道
完成训练或精调后，只需直接调用 diffuser 库+加载自己保存的模型参数
->模型推理对数值精度不敏感
from diffusers import StableDiffusionPipeline
pipe = StableDiffusionPipeline.from_pretrained("your_ColoDiffusion_checkpoint_path").to("cuda")
image = pipe('your prompt', num_inference_steps=50)["sample"][0]
image.save('file path')
Colossal-AI+diffusion
- Colossal-AI训练diffusion项目地址 github
- ldm项目地址 github
- ldm代码教程
We provide the script train_colossalai.sh to run the training task with colossalai, and can also use train_ddp.sh to run the training task with ddp to compare.
可以通过 train_colossalai.sh 来执行训练任务：
python main.py --logdir /tmp/ --train --base configs/train_colossalai.yaml --ckpt 512-base-ema.ckpt
You can change the --logdir to decide where to save the log information and the last checkpoint.
You will find your ckpt inlogdir/checkpointsorlogdir/diff_tb/version_0/checkpoints
You will find your train config yaml inlogdir/configs
You can add the --ckpt if you want to load the pretrained model, for example 512-base-ema.ckpt
You can change the --base to specify the path of config yaml
Training config
train_colossalai.yaml中可以修改的一些参数
devices: device number used for training, default 8
max_epochs: max training epochs, default 2
precision: the precision type used in training, default 16 (fp16), you must use fp16 if you want to apply colossalai
环境配置

使用Colossal-AI需下载pytorch-lightning>=1.8.1
Colossal-AI 已集成作为 PyTorch Lightning 的官方大模型解决方案
Step 2: install lightning
Install Lightning version later than 2022.01.04. We suggest you install lightning from source.注意太早的 pytorch-lightning 版本没有strategy更没有ColossalAIStrategy，
经测试1.4.1和1.6.1版本都报错或者warning了，最后换到1.8.1成功跑通
pip install pytorch-lightning==1.8.1 -
3090需下载 CUDA >= 11.6版本
否则报如下提示NVIDIA GeForce RTX 3090 with CUDA capability sm_86 is not compatible with the current PyTorch installation.
The current PyTorch install supports CUDA capabilities sm_37 sm_50 sm_60 sm_61 sm_70 sm_75 compute_37.参考如下文章
解决：NVIDIA GeForce RTX 3090 with CUDA capability sm_86 is not compatible with … -
xformer需要pytorch>=1.13.1
- pytorch 1.13.1
torchvision 0.14.1
cuda 11.7
按environment.yaml配的初始环境会报如下错误：
/home/user/anaconda3/envs/colossalai/lib/python3.7/site-packages/torchvision/io/image.py:11: UserWarning: Failed to load image Python extension: libtorch_cuda_cu.so: cannot open shared object file: No such file or directory
warn(f"Failed to load image Python extension: {e}")
应该时torchvision有问题，重新安装pytorch，经测试如下版本可成功跑通
conda install pytorch torchvision torchaudio pytorch-cuda=11.7 -c pytorch -c nvidia
- 师兄采用
pytorch 1.12.1
torchvision 1.13.1
cuda 11.6
conda install pytorch==1.12.1 torchvision==0.13.1 torchaudio==0.12.1 cudatoolkit=11.6 -c pytorch -c conda-forge
会报如下提示

因为之前跑stable diffusion不会出现这个问题，分析要么是colossalai加的代码有问题，要么是包冲突。
已向colossalai的github提交issue等待回复中…
- 尝试输出报错信息进行定位
在我们运行程序的时候，经常会遇到Segmentation fault (core dumped)的问题，这种问题多见于内存操作不当，比如空指针、野指针的读写操作，数组越界访问，常量被破坏等。对于一个比较大的程序，比较难定位错误具体的位置，因此我们需要利用core文件进行错误的查找。
[解决问题]查找产生Segmentation fault (core dumped)错误的真正原因
如何生成和调试 Linux 程序崩溃产生的 core 文件
查资料得知core dumped问题可以通过core文件查看报错
1.ulimit -c unlimited #不限制core文件大小
此时，程序产生core dump时会自动生成core文件在默认生成路径中
2.如果没有看到core文件可以修改生成路径到当前文件夹
例如：
sudo sysctl -w kernel.core_pattern=core.%p
3.core文件查看方式
gdb sysbench core.37795
或者进入gdb后
core-file core.7416
...
[New LWP 39080]
Core was generated by `python main.py --logdir tmp --train --base configs/train_colossalai_cifar10.yaml'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0 0x00007fba24575540 in ?? ()
[Current thread is 1 (LWP 37795)]
报错的是这一句Program terminated with signal SIGSEGV
SIGSEGV意思是程序企图向分配的内存以外的区域读写，或者向只读区域进行写操作（访问空指针，内存越界访问，访问已经释放的内存…）
非常难受的是，范围太广了难以定位。
尝试gdb调试python
