 # :building_construction: Installation
 
+Note: this assumes you have `numpy` and `torch` installed

 **Training models with Megatron-LM:** We recommend using NGC's [`nvcr.io/nvidia/pytorch:23.01-py3`](https://catalog.ngc.nvidia.com/orgs/nvidia/containers/pytorch/tags) PyTorch container. The [Dockerfile](Dockerfile) builds on this image with additional dependencies. To build the image, run `docker build . -t megablocks-dev` and then `bash docker.sh` to launch the container. Once inside the container, install MegaBlocks with `pip install .`. See [Usage](#steam_locomotive-usage) for instructions on training MoEs with MegaBlocks + Megatron-LM.
 
 **Using MegaBlocks in other packages:** To install the MegaBlocks package for use in other frameworks, run `pip install megablocks`.
