## MMSegmentation Support

MMSegmentation is an open source object segmentation toolbox based on PyTorch. It is a part of the [OpenMMLab](https://openmmlab.com/) project.

### MMSegmentation installation tutorial

Please refer to [get_started.md](https://github.com/open-mmlab/mmsegmentation/blob/master/docs/get_started.md) for installation.

### Reminder

- Only `whole` inference mode is supported for all mmseg models.

- <i id="pspnet">PSPNet</i> only supports static shape, better to use the deployment config file of static shape such as `configs/mmseg/segmentation_tensorrt_static-512x1024.py`. Because [nn.AdaptiveAvgPool2d](https://github.com/open-mmlab/mmsegmentation/blob/97f9670c5a4a2a3b4cfb411bcc26db16b23745f7/mmseg/models/decode_heads/psp_head.py#L38) in psp_head is not supported in most of backends dynamically.
