Install script of caffe2 and detectron on AWS EC2 instance with Deep Learning Base AMI

install_caffe2_detectron.sh

# Install script of Caffe2 and Detectron on AWS EC2
#
# Tested environment:
#   - AMI: Deep Learning Base AMI (Ubuntu) Version 6.0 - ami-ce3673b6  (CUDA is already installed)
#   - Instance: p3.2xlarge (V100 * 1)
#   - Caffe2: https://github.com/pytorch/pytorch/commit/731273b8d61dfa2aa8b2909f27c8810ede103952
#   - Detectron: https://github.com/facebookresearch/Detectron/commit/cd447c77c96f5752d6b37761d30bbdacc86989a2
#
# Usage:
#   Launch a fresh EC2 instance, put this script on the /home/ubuntu/, and run the following command.
#   $ cd ~
#   $ source install_caffe2_detectron.sh
#
# Test:
#   $ cd ~/work/detectron/detectron
#   $ python2 tests/test_spatial_narrow_as_op.py
#
# Run samples:
#   Run the following commands and see the results in /tmp/detectron-visualizations
#   $ cd ~/work/detectron
#   $ python2 tools/infer_simple.py \
#    --cfg configs/12_2017_baselines/e2e_mask_rcnn_R-101-FPN_2x.yaml \
#    --output-dir /tmp/detectron-visualizations \
#    --image-ext jpg \
#    --wts https://s3-us-west-2.amazonaws.com/detectron/35861858/12_2017_baselines/e2e_mask_rcnn_R-101-FPN_2x.yaml.02_32_51.SgT4y1cO/output/train/coco_2014_train:coco_2014_valminusminival/generalized_rcnn/model_final.pkl \
#    demo
#
# Note that:
#   - In the Deep Learning AMI (Version 4.0), CUDA and caffe2 are already installed. But the caffe2 in the AMI is
#     a bit old version and does not include some modules required for Detectron.
#     So this script supposes that an AMI is Deep Learning "Base" AMI (Version 6.0), where only CUDA is installed.
#   - Manual configuration of setup.py is not a recommended way. Any suggestions are welcome.

@matsui528 if I use script you have above, it prompts below and then fails.

Hi there,
Updated the code and now it should work with the latest Deep Learning Base AMI (Version 6.0 - ami-ce3673b6)

Hi there,
Now we can install the latest caffe2 easily via conda install pytorch-nightly -c pytorch. This means we can use Deep Learning AMI (not Deep Learning "Base" AMI) directly. Note that python2 with conda environment is pre-installed in DL AMI. Here is the install script for the latest DL AMI:

# - Deep Learning AMI (Ubuntu) Version 19.0 - ami-05bc59103c52af154
# - Tested on p3.8xlarge
# - We use pytorch_p27 environment of conda
# - Note that it seems "sudo apt upgrade" fails for a while right after an instance is launced. It would be recommended to reboot the instance first of all, and make sure "sudo apt update" and "sudo apt upgrade" work, then run this script.

# Install the latest pytorch
sudo apt -y update
sudo apt -y upgrade
source activate pytorch_p27
conda install -y pytorch-nightly -c pytorch
conda install -y future cython

# Install COCOAPI
INSTALL_DIR=~/work
mkdir -p $INSTALL_DIR

COCOAPI=$INSTALL_DIR/cocoapi
git clone https://github.com/cocodataset/cocoapi.git $COCOAPI
cd $COCOAPI/PythonAPI
make install

# Install detectron
DETECTRON=$INSTALL_DIR/detectron
git clone https://github.com/facebookresearch/detectron $DETECTRON
pip install -r $DETECTRON/requirements.txt
cd $DETECTRON
make

@matsui528 thanks for putting this on gist. Tried your pytorch-nightly solution on same exact AMI you tested on, but getting protobuf errors. How did you solve the protobuf incompatibility problem?

TypeError: __new__() got an unexpected keyword argument 'serialized_options'

Here is how to fix the protobuf problem:

pip uninstall protobuf
pip install protobuf==3.6.1

...however, now I have a new problem:

(pytorch_p27) ubuntu@ip-10-60-1-125:~/work/detectron$ python -c 'from caffe2.python import workspace; print(workspace.NumCudaDevices())'
WARNING:root:This caffe2 python run does not have GPU support. Will run in CPU only mode.
Segmentation fault (core dumped)

That is on Deep Learning AMI (Ubuntu) Version 23.1 (ami-0757fc5a639fe7666) and a P3.2xl

Update: I had to build and install PyTorch/Caffe2 from source and things seem to be working now.
