Missing License

The license for this project is missing, which indicates it is "actually not open source" project.

> **[Licensing a repository](https://help.github.com/en/github/creating-cloning-and-archiving-repositories/licensing-a-repository)**
> Public repositories on GitHub are often used to share open source software. For your repository to truly be open source, you'll need to license it so that others are free to use, change, and distribute the software.

I am assuming the license for this project is exactly the same as [CSAILVision/semantic-segmentation-pytorch](https://github.com/CSAILVision/semantic-segmentation-pytorch/blob/master/LICENSE).

Review the linked CSAILVision/semantic-segmentation-pytorch LICENSE and compare it with this repository, since the issue assumes the same license should apply. Check the repository contents and confirm the project’s intended license with maintainers; done means the repository has an agreed license file.
