Usage

1. Installation

Please install the latest ColossalAI from source.

bash

CUDA_EXT=1 pip install -U git+https://github.com/hpcaitech/ColossalAI

Then install dependencies.

bash

cd ColossalAI/applications/ColossalMoE
pip install -e .

Additionally, we recommend you to use torch 1.13.1. We've tested our code on torch 1.13.1 and found it's compatible with our code.

2. Inference

Yon can use colossalai run to launch inference:

bash

bash infer.sh

If you already have downloaded model weights, you can change name to your weights position in infer.sh.

3. Train

You first need to create ./hostfile, listing the ip address of all your devices, such as:

bash

111.111.111.110
111.111.111.111

Then yon can use colossalai run to launch train:

bash

bash train.sh

It requires 16 H100 (80G) to run the training. The number of GPUs should be divided by 8. If you already have downloaded model weights, you can change name to your weights position in train.sh.
