OpenSTL Release V0.1.0 (SimVPv2)

Release version to SimVPv2 V0.1.0. This version is also known as OpenSTL V0.1.0. We have separated a branch for SimVPv2 since we plan to refactor this project with advanced features.

[2023-05-06] We add some meta files in this release to facilitate downloading.
[2023-06-04] We release the test sets of MMNIST datasets. Please refer to install.md for dataset preparation in OpenSTL.
[2023-06-26] We add kth_action.zip in the image format (.jpg) for the kth dataloader.

Features

• Refactor code structures as simvp/api, simvp/core, simvp/datasets, simvp/methods, simvp/models, simvp/modules. We support non-distributed training and evaluation by the executable python file tools/non_dist_train.py. Refactor config files for SimVP models.
• Fix bugs in tools/nondist_train.py, simvp/utils, environment.yml, and .gitignore, etc.
• Support Timm optimizers and schedulers.
• Update popular Metaformer models as the hidden Translator $h$ in SimVP, supporting ViT, Swin-Transformer, MLP-Mixer, ConvMixer, UniFormer, PoolFormer, ConvNeXt, VAN, HorNet, and MogaNet.
• Update implementations of dataset and dataloader, supporting KTH Action, KittiCaltech Pedestrian, Moving MNIST, TaxiBJ, and WeatherBench.

Documents

• Upload readthedocs documents. Summarize video prediction benchmark results on MMNIST in video_benchmarks.md.
• Update benchmark results of video prediction baselines and MetaFormer architectures based on SimVP on MMNIST, TaxiBJ, and WeatherBench datasets.
• Update README and add a license.
