+Some sub-modules require additional dependencies which are discussed below
 
 * **ot.dr** (Wasserstein dimensionality reduction) depends on autograd and pymanopt that can be installed with:
 
 ```shell
 pip install pymanopt autograd
 ```
 
-* **ot.gpu** (GPU accelerated OT) depends on cupy that have to be installed following instructions on [this page](https://docs-cupy.chainer.org/en/stable/install.html). Obviously you will need CUDA installed and a compatible GPU. Note that this module is deprecated since version 0.8 and will be deleted in the future. GPU is now handled automatically through the backends and several solver already can run on GPU using the Pytorch backend.
