#!/bin/bash

# This script helps developers set up the ONNX Caffe2 and PyTorch develop environment on devgpu.
# It creates an virtualenv instance, and installs all the dependencies in this environment.
# The script will creates a folder called onnx-dev folder under the $HOME directory.
# onnx, pytorch and caffe2 are installed separately.
# Please source $HOME/onnx-dev/.onnx_env_init to initialize the development before starting developing.
