Software

Torch version is 1.7.1. Python version is 3.7.6. CUDA version is 11.0.

These python files, of cause, require some basic scientific computing python packages, e.g., numpy. I recommend users to install python via Anaconda (python 3.7.6), which can be downloaded from https://www.anaconda.com/distribution/#download-section . If you have installed Anaconda, then you do not need to worry about these basic packages.

After you install anaconda and pytorch (gpu), you can run codes successfully.

MEDI

Please feel free to test the MEDI method by running main.py.

Specifically, please run

CUDA_VISIBLE_DEVICES=0 python main.py

in your terminal (using the first GPU device).
