Train a model

Run the following command to train a model using a specified config.

# Single GPU
python tools/launch.py ${path-to-config}

# Multiple GPUs
torchrun --nproc_per_node=${num-gpus} tools/launch.py ${path-to-config}

Test a model and evaluate results

Run the following command to test a model and evaluate results.

python tools/launch.py ${path-to-config} --checkpoint ${path-to-checkpoint} --eval

Pre-train with ASR captions on QVHighlights

Run the following command to pre-train a model using ASR captions on QVHighlights.

torchrun --nproc_per_node=4 tools/launch.py configs/qvhighlights/umt_base_pretrain_100e_asr.py

Model Zoo

We provide multiple pre-trained models and training logs here. All the models are trained with a single NVIDIA Tesla V100-FHHL-16GB GPU and are evaluated using the default metrics of the datasets.

Here, w/ PT means initializing the model using pre-trained weights on ASR captions. V, A, and O indicate video, audio, and optical flow, respectively.
