This project studies how to learn generalizable visual representation for robotics from videos of humans and natural language. It contains pre-trained representation on the Ego4D dataset trained in the R3M paper
To install R3M from an existing conda environment, simply run pip install -e . from this directory.
You can alternatively build a fresh conda env from the r3m_base.yaml file here and then install from this directory with pip install -e .
You can test if it has installed correctly by running import r3m from a python shell.
To use the model in your code simply run:
from r3m import load_r3m
r3m = load_r3m("resnet50") # resnet18, resnet34
r3m.eval()
Further example code to use a pre-trained representation is located in the example here.
If you have any issue accessing or downloading R3M please contact Suraj Nair: surajn (at) stanford (dot) edu
To train the representation run:
python train_representation.py hydra/launcher=local hydra/output=local agent.langweight=1.0 agent.size=50 experiment=r3m_test dataset=ego4d doaug=rctraj agent.l1weight=0.00001 batch_size=16 datapath=<PATH TO PARSED Ego4D DATA> wandbuser=<WEIGHTS AND BIASES USER> wandbproject=<WEIGHTS AND BIASES PROJECT>
Note: For fast training, the Ego4D data loading code assumes that the dataset has been parsed into frames, with a folder for each video clip and frames of the videoclip (resized to [224 x 224]) numbered within the directory (for example 000123.jpg). It also assumes a file called manifest.csv which has a row for each clip, with the path to the clip folder, the clip length, and the natural language pairing for the clip.
