'pytorch_lightning.strategies' has no attribute 'ColossalAIStrategy'

Hi, I already installed the following packages with the guide of "Installation" pytorch-lightning 1.6.5 colossalai 0.1.11rc3+torch1.11cu11.4

But when I run training, it reports following error: AttributeError: module 'pytorch_lightning.strategies' has no attribute 'ColossalAIStrategy'

The yaml I used is as following: `model: base_learning_rate: 1.0e-04 target: ldm.models.diffusion.ddpm.LatentDiffusion params: linear_start: 0.00085 linear_end: 0.0120 num_timesteps_cond: 1 log_every_t: 200 timesteps: 1000 first_stage_key: image cond_stage_key: txt image_size: 64 channels: 4 cond_stage_trainable: false # Note: different from the one we trained before conditioning_key: crossattn monitor: val/loss_simple_ema scale_factor: 0.18215 use_ema: False

Do you have any idea about this error? Thanks a lot.

pytorch-lightning

you can try pytorch-lightning == 1.8

You can fix the bug with the correct PL version. I closed the issue.
