Training Script stablity 3B and 7B #72
Description
`# Developed by Aamir Mirza
create a conda virtual environment python 3.9
install PyTorch 1.13.1 ( not 2.0)
conda install pytorch==1.13.1 torchvision==0.14.1 torchaudio==0.13.1 pytorch-cuda=11.7 -c pytorch -c nvidia
install the latest transformers
conda install -c conda-forge transformers
install deepspeed from GitHub not pip install
build deepspeed with CPU Adam optimiser support like this
git clone https://github.com/microsoft/DeepSpeed
DS_BUILD_CPU_ADAM=1 pip install .
accelerate via pip
pip install Ninja
conda install -c conda-forge mpi4py
train via commandline for example
deepspeed train_gptNX_v2.py --num_gpus=2
In my case I have 2x 3090 24GB

Change this to your requirement for example 4096 (MAX)
