S4D gets "best" 89.76% accuracy after 100 epochs @ 1m32s/epoch on an A100
The alternative S4D-Lin initialization performs slightly better with 90.98% accuracy.

We have two requirements.txt files that hold dependencies for the current project: one that is tailored to CPUs,
the other that installs for GPU.
# Set up virtual/conda environment of your choosing & activate...
pip install -r requirements-cpu.txt
# Set up pre-commit
pre-commit install# Set up virtual/conda environment of your choosing & activate...
pip install -r requirements-gpu.txt
# Set up pre-commit
pre-commit installIn case the above requirements.txt don't work, here are the commands used to download dependencies.
# Set up virtual/conda environment of your choosing & activate... then install the following:
pip install --upgrade "jax[cpu]"
pip install flax
pip install torch torchvision torchaudio
# Defaults
pip install black celluloid flake8 google-cloud-storage isort ipython matplotlib pre-commit seaborn tensorflow tqdm
# Set up pre-commit
pre-commit installNote - CUDNN > 8.2 is critical for compilation without warnings, and GPU w/ at least Turing architecture for full efficiency.
