Octo Experiments

This is a repository for some experiments with the Octo model.

Setup

These steps have to be undertaken in bash since shells like zsh try to match on square brackets.

mamba create -n octo python=3.10
mamba activate octo
python -m pip install tensorflow[and-cuda]==2.14.0
python -c "import tensorflow as tf; print(tf.config.list_physical_devices('GPU'))"

mamba install cudnn=8.8 cuda-version=11.8
pip install --upgrade "jax[cuda11_pip]==0.4.20" -f https://storage.googleapis.com/jax-releases/jax_cuda_releases.html

Some warnings and even errors from Tensorflow seem to be normal and acceptable, see also this article. In Octo, Tensorflow is mainly used for dataloading, not for the model themselves.

Verify GPU support in JAX is working:

from jax.lib import xla_bridge
print(xla_bridge.get_backend().platform)

Then, go on to install the other requirements:

cd octo
pip install -e .
pip install -r requirements.txt
