DeepSpeed Integration for MMDetection3d

Setup

Init and update MMDetection3d submodule

git submodule init
git submodule update

Install MMDetection3d submodule using the instructions at https://mmdetection3d.readthedocs.io/en/latest/getting_started.html#installation. Remember to install the submodule inside this repository.
Second, install DeepSpeed like:

git clone https://github.com/microsoft/DeepSpeed.git
cd DeepSpeed
DS_BUILD_OPS=1 ./install.sh
cd ..

Third, install NVIDIA Apex like:

git clone https://github.com/NVIDIA/apex
cd apex
pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./
cd ..

Symlink the Lyft dataset like

mkdir -p ./data/
# ln -s path/to/lyft/data /path/to/deepspeed_mmdetection3d/data/
ln -s /home/hd10/data/lyft /home/hd10/deepspeed_mmdetection3d/data/

Running

Run FP16 training like

nohup deepspeed --num_nodes 1 --num_gpus 1 ds/train.py --work-dir ./outputs_fp16/ --gpus 1 configs/ssn/ssn_lyft_base.py --deepspeed_config configs/ds/ds_config_fp16.json &

Run AMP training like

nohup deepspeed --num_nodes 1 --num_gpus 1 ds/train.py --work-dir ./outputs_amp/ --gpus 1 configs/ssn/ssn_lyft_base.py --deepspeed_config configs/ds/ds_config_amp.json &
