Dataset Viewer

The dataset could not be loaded because the splits use different data file formats, which is not supported. Read more about the splits configuration. Click for more details.

Couldn't infer the same data file format for all splits. Got {NamedSplit('validation'): ('imagefolder', {}), NamedSplit('test'): (None, {})}

Error code:   FileFormatMismatchBetweenSplitsError

Need help to make the dataset viewer work? Make sure to review how to configure the dataset viewer, and open a discussion for direct support.

Demo

CAD

TRLC-DK1 v0.2.0 Follower CAD (Fusion)

TRLC-DK1 v0.2.0 Leader CAD (Fusion)

Installation

conda create -n dk1 python=3.10
conda activate dk1
pip install -e .

(This should also install TRLC's fork of LeRobot and use branch trlc-dk1)

Examples

Use LeRobot's CLI to identify your teleop and robot ports:

lerobot-find-port
