-We recommend using an instance type of **c6i.4xlarge, c6i.8xlarge, c6i.12xlarge, or higher** for optimal performance. Using an instance type with too little memory will result in an error during the `conda env create -f` step, if you run into an error during the `conda env` step then try a larger instance type.
