Comprehensive Guide: Installing Caffe2 with GPU Support by Building from Source on Ubuntu 16.04

In the previous posts, we have gone through the installation processes for deep learning infrastructure, such as Docker, nvidia-docker, CUDA Toolkit and cuDNN. With the infrastructure setup, we may conveniently start delving into deep learning: building, training, and validating deep neural network models, and applying the models into a certain problem domain. Translating deep learning primitives into low level bytecode execution can be an enormous task, especially for practitioners without interests in the deep learning calculus. Fortunately, there are several deep learning frameworks that provide the high level programming interface to assist in performing deep learning tasks.

In this post, we will go through the installation of Caffe2, one of the major deep learning frameworks. Caffe2 is adopted from Caffe, a deep learning framework developed by the Barkeley Vision and Learning Center (BVLC) of UC Berkeley. Caffe2 was started with the aim to improve Caffe especially to better support large-scale distributed model training, mobile deployment, reduced precision computation, new hardware, and flexibility of porting to multiple platforms.

Why Installing from Source?

It is important to note that instead of installation by building from source, there are some easier options, as for example by pulling and running Caffe2 Docker images. The Docker repository for Caffe2 images is accessible here. Nonetheless, if you observe the list, the images are not recent and they were built against older version of CUDA toolkit and cuDNN. Therefore, one who intends to fiddle with latest Caffe2, CUDA, or cuDNN features may seriously consider installing from source.

Caffe2 Is Now A Part of Pytorch

In the past, Caffe2 source was maintained as an independent repository on Github. This changed from the end of March 2018 since Caffe2 repository was merged into Pytorch repository. Consequently, the common build process is now integrated into that of Pytorch.

There can be questions about the motivation of the source code merging. As explained in the announcement post, the merging was preceded by the development infrastructure sharing between Caffe2 and Pytorch that led into increasing amount of shared code and common libraries. It was then concluded that merging the two projects into one codebase would result in better engineering efficiency and increase the robustness of the framework especially in the area of model deployment.

What if Caffe2 has been previously installed? When installing Caffe2 prior to the source code merging, the build process would output header files, dynamic library and python library that subsequently copied to designated directories. In theory, it would suffice to replace the old header and library files with the one from the newest build. If it does not work, a clean up is necessary by first removing the old files from their installed directories prior to proceeding with the installation

Pre-Requisites

We will be installing Caffe2 with GPU support. This article only covers the installation process for machines with NVIDIA GPUs. Verify that these items are satisfied prior to going through the installation.

1. Verify that NVIDIA graphics driver has been properly installed.

You can refer to this article for NVIDIA graphics driver installation and functionality checking.

2. Verify that CUDA toolkit has been installed.
If you have not installed CUDA toolkit, are unsure whether it is already installed, or want to install the newer version of CUDA toolkit, refer to this article that provides more elaboration about CUDA toolkit installation.

3. Verify that cuDNN has been installed.
You can refer to this article for more details about cuDNN installation

4. Remove files from previous Caffe2 installation
If you have installed Caffe2 earlier and want to do an upgrade, you may need to clean the files created and copied in the previous Caffe 2 installation.
Note: this can usually be skipped as the build tool will first check the existing version of Caffe2 installed in the system prior to replacing it with a new one


$ sudo rm -vRf /usr/local/include/caffe2
$ sudo rm -vf /usr/local/lib/libcaffe2*

Additionally, we may need to remove the python APIs from the Python package directory (path may vary depending on the installed Python version).

$ sudo rm -vRf /usr/local/lib/python2.7/dist-packages/caffe2

After checking all the prerequisites, we can now proceed with the installation.

Installation Steps

The installation can be accomplished by going through these steps in order.

Step 1. Update apt package index
$ sudo apt-get update

Step 2. Install apt package dependencies

remote$ sudo apt-get install -y --no-install-recommends build-essential cmake git libgoogle-glog-dev libgtest-dev libiomp-dev libleveldb-dev liblmdb-dev libopencv-dev libopenmpi-dev libsnappy-dev libprotobuf-dev openmpi-bin openmpi-doc protobuf-compiler python-dev python-pip

Step 3. Install pip dependencies

$ sudo pip install --upgrade pip
$ sudo pip install setuptools future numpy protobuf
$ sudo apt-get install -y --no-install-recommends libgflags-dev

Step 4. Clone Caffe 2 into a local directory
Note: We create a directory named caffe2-pytorch and clone Pytorch git repository into this directory.

$ mkdir caffe2-pytorch && cd caffe2-pytorch
$ git clone --recursive https://github.com/pytorch/pytorch.git ./
$ git submodule update --init

Step 5. Build Caffe 2

$ mkdir build && cd build
$ cmake ..
$ sudo make -j"$(nproc)" install

Note: when building the source, we supply the -j flag. The flag refers to the number of threads that can be spawned by the compiler (i.e. GCC) when building the source code. The nproc command itself will print the number of the CPUs available. In short, we want to speed up the compilation time by creating a number of threads that amount to the number of CPUs to perform the compilation in parallel.

Step 6. Create the symbolic link for Caffe 2 shared library
$ sudo ldconfig

Step 7. Verify that Caffe 2 library and the headers have been installed in the proper directory
– Update the locate database
$ sudo updatedb

– Ensure that libcaffe2.so is located in /usr/local/lib
$ locate libcaffe2.so

– Ensure that the header files have been copied into /usr/local/include
$ locate caffe2 | grep /usr/local/include/caffe2

Step 8. Add Caffe2 into python and library paths so that it can be immediately discovered and linked by other applications.
$ vim ~/.profile

…
# set python path
if [ -z “$PYTHONPATH” ]; then
    PYTHONPATH=/usr/local
else 
    PYTHONPATH=/usr/local:$PYTHONPATH
fi

#set library path
if [ -z “$LD_LIBRARY_PATH” ]; then
    LD_LIBRARY_PATH=/usr/local/lib
else
    LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
fi
…

We can also set the library paths using parameter expansion as follows:

...
PYTHONPATH=/usr/local${PYTHONPATH:+:${PYTHONPATH}}
LD_LIBRARY_PATH=/usr/local/lib${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
...

We then immediately export the new paths by invoking the source command as follows.
$ source ~/.profile

Alternatively, we can use the dot (.) command, to execute ~/.profile file and enable the new environment variables in the current shell.
$ . ~/.profile

Step 9. Verify that the Caffe2 python module can be properly invoked
$ python -c 'from caffe2.python import core' 2>/dev/null && echo "Success" || echo "Failure"

Step 10. Verify that Caffe2 can run with GPU support
$ python2 -c 'from caffe2.python import workspace; print(workspace.NumCudaDevices())'

The installation is now complete. We can now start using Caffe2 for deep learning modeling and implementation. If you have problem with your Caffe2 installation, simply write it in the comment section.

      # Caffe2 python run does not have GPU support

      ### system info

      – PyTorch or Caffe2: Caffe2
      – OS: ubuntu16.04
      – How I installed Caffe2: source
      – Python version: python 3.6.0
      – CUDA/cuDNN version:8.0.61/7.0.5
      – GPU models and configuration:Nvidia GTX 1080
      – GCC version:5.4.0
      – cmake version: 3.5.1
      – miniconda

      ### What I did

      – I have tried to build caffe2 from source (following [this](https://caffe2.ai/docs/getting-started.html?platform=ubuntu&configuration=compile#install-with-gpu-support)):

      After I installed the dependencies on that page and clone the repository, I run this command `FULL_CAFFE2=1 python setup.py install`. I test `from caffe2.python import core` and I got `Failure`

      – Then I find a solution in github [following this(@kaisark)](https://github.com/pytorch/pytorch/issues/6259)

      I passed the test and got Success but I found it doesn’t support GPU.

      Any reason that prevented you from upgrading to CUDA 9? I haven’t tested the build for CUDA 8, so this might not be the best suggestion that you can get.

      You may need to check the location of libcaffe2_gpu.so in the system using this command:
      $ locate libcaffe2 | grep libcaffe2_gpu

      Make sure that this library is located in the same directory with libcaffe2.so. If the library does not exist, you need to rebuild from source again.

    Hi, Thanks for the detailed installing instruction. I am trying to install caffe2 on my machine, but keep getting this error. Could you guide me to resolve the issue.

      Error code 2 means that the file (caffe2_pybind11_state_gpu.so) does not exist. If the source was building properly the .so file should have beeen located under SRC_HOME/build/caffe2/python/ directory. A possible cause is that cmake could not find CUDA. Could you paste the output of “echo $LD_LIBRARY_PATH”, “echo $PYTHONPATH”, and the output of cmake for CUDA:
      USE_CUDA : ON/OFF
      CUDA version : x.x.x

      If you follow the steps explained in the article, USE_CUDA must be ON and CUDA version must be 9.1.

      At first glance, that configuration looks fine. I suppose CUDA 9.2 did not play nice with cuDNN 6.0, but this should be further validated because i have yet to configure with that kind of CUDA-cuDNN version pair.

      If you can also provide the output for “nvidia-smi” and “nvcc –version” commands, it can add more datapoints for the root cause analysis.

      Additionally, you may consider upgrading cuDNN to 7.1.x and recompile again.

      Looking at the log this time, it’s more obvious that the error was caused by Open MPI. You may have not installed Open MPI or the library files are not linked properly.

      Quick resolve: Build without Open MPI support
      $ cmake .. -DUSE_MPI=OFF

      Robust resolve: Track the Open MPI status, install if it has not been installed or fix the library linking
      – To check if Open MPI has been installed
      $ mpirun --version

      – To check where the library is located
      $ locate libmpi

      – To search Open MPI in apt repositories
      $ apt-cache search openmpi

      – To install relevant Open MPI libraries
      $ sudo apt-get install libopenmpi-dev libopenmpi1.10 openmpi-bin openmpi-common openmpi-doc

      This issue is a known Caffe2 issue. You can find more info about it here: https://github.com/caffe2/caffe2/issues/2144

      Glad to know it resolved your issue. As a side note, if you’re building a cluster (GPU/CPU), it’s suggested to compile with Open MPI support. -Mike-

      This could be a problem with protobuf version. You may need to check the current protobuf lib version installed.
      $ pip show protobuf

      There can be incompatibility issue with the most recent protobuf installed via pip against your caffe2 environment. i also noticed that you have CUDA 9.0 instead of the most recent 9.2 installed.

    I did a new fresh installation of Caffe2 again, and this time, sudo make install is outputting errors.

      The instruction in Pytorch uses Anaconda while this article builds directly on the OS.

    I was able to build with CPU only, but am having the following error on GPU. (I tested cuda 9.2, 9.1, 9.0, with cudnn7, and cuda 8.0 with cudnn6. All these combination will have the following error information).

      That’s the problem with GCC not Caffe2 sources. You were compiling with GCC 5.5 and may need to consider downgrading to GCC 5.4 in order to build successfully. This is a known issue that is also faced by other frameworks. You can refer to similar problem for TensorFlow discussed here: https://github.com/tensorflow/tensorflow/issues/10220

    Hi Mikael, I’ve been following your steps. Though, during the Step 5, I got the following errors and couldn’t make it successful – any advice or suggestions?

      Hi Bryan,
      Could you provide the info about your build environment:
      – OS version
      – GCC version
      – Python version
      – CUDA version
      – cuDNN version
      – the output of the following commands:
      $ echo $LD_LIBRARY_PATH
      $ echo $PYTHONPATH

      – and the output of cmake for CUDA?

      Did you also try to build from the latest Caffe2 source?

  10. Bryan

    Hi Mikael,

    Here is the info you requested – let me know if you need anything else

    1. OS: Ubuntu 16.04
    2. GCC version 5.4.0 20160609
    3. Python versions: 2,7 and 3.5
    4. CUDA 9.0.176
    5. CuDNN 7.1.4
    6. echo $LD_LIBRARY_PATH: /usr/local/cuda-9.0/lib64:/usr/local/cuda/extras/CUPTI/lib64
    7. echo $PYTHONPATH: (null)
    8. Regarding the latest Caffe2 source, can you explain? I’ve just followed the step 4
    9. Output of cmake for CUDA

      I updated the cmake version from 3.5.1 to 3.12.0 and retried but again failed for the same errors (as shown below) – any thoughts?

      Is this a compatibility issue? Would you suggest to change from CUDA 9.0 / cuDNN 7.1 possibly to lower versions (e.g., CUDA 8.0 / cuDNN 6.0)?

      Hi Bryan,

      Thanks for providing the information about your build environment and also the link to the Github issue. Looking at the log, the problem might be caused by non-matching cuDNN library for building Caffe2. As you built with CUDA 9.0, it’s also necessary to find the correct cuDNN version for CUDA 9.0. There can be incompatibility between recent cuDNN and older version of CUDA.

      My suggestion is to upgrade to newer version of CUDA, for e.g. CUDA 9.2 (I haven’t tested CUDA 10.0), and install cuDNN that matches CUDA 9.2. When you login to NVIDIA developer portal, you will be able to find cuDNN deb file for CUDA 9.2.

      If you want to stick with CUDA 9.0, you need to install compatible cuDNN for CUDA 9.0.

      From this error:

      /usr/local/cuda-9.0/lib64/libcudnn.so: error adding symbols: File in wrong format

      It hinted cuDNN incompatibility. You may need to check once again if cuDNN 7.1.4 is compatible with CUDA 9.0.

      This issue may also give you additional pointer to resolve the issue: https://github.com/caffe2/caffe2/issues/1887
