Ubuntu 18.04 源碼安裝 caffe 步驟 【自用】

安裝環境

1. OS: Ubuntu 18.04 64 bit
2. 顯卡: NVidia RTX 2080Ti
3. CUDA: 10.1
4. cuDNN: 7.5
5. Python: 3.6

安裝 OpenCV

1. OpenCV 安裝步驟

安裝依賴

$ sudo apt install -y libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler
$ sudo apt install -y --no-install-recommends libboost-all-dev
$ sudo apt install -y libatlas-base-dev
$ sudo apt install -y libgflags-dev libgoogle-glog-dev liblmdb-dev

下載源碼

$ git clone https://github.com/BVLC/caffe.git
$ cd caffe
$ cp Makefile.config.example Makefile.config

修改配置

1. 修改 Makefile.config 如下：

...
USE_CUDNN := 1
...
OPENCV_VERSION := 3
...
CUDA_DIR := /usr/local/cuda-10.1
...
CUDA_ARCH :=    \
                -gencode arch=compute_30,code=sm_30 \
                -gencode arch=compute_35,code=sm_35 \
                -gencode arch=compute_50,code=sm_50 \
                -gencode arch=compute_52,code=sm_52 \
                -gencode arch=compute_60,code=sm_60 \
                -gencode arch=compute_61,code=sm_61 \
                -gencode arch=compute_61,code=compute_61
...
MATLAB_DIR := /usr/local/MATLAB/MATLAB_Production_Server/R2015a
...
# Uncomment to use Python 3 (default is Python 2)
PYTHON_LIBRARIES := boost_python3 python3.6m
PYTHON_INCLUDE :={$HOME}/.virtualenvs/py3caffe/include/python3.6m \
            {$HOME}/.virtualenvs/py3caffe/lib/python3.6/site-packages
...
WITH_PYTHON_LAYER := 1
...
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial /usr/local/cuda/include /usr/local/include/opencv2
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/hdf5/serial

編譯

$ make -j8
$ make pycaffe
$ make matcaffe

測試 pycaffe

$ python
Python 3.6.9 (default, Apr 18 2020, 01:56:04)
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import caffe

1. 缺什麼庫則使用 pip 安裝。

測試 matcaffe

$ make mattest

1. 若遇到類似問題：

Invalid MEX-file ‘**/caffe.mexa64’
/usr/local/MATLAB/MATLAB_Production_Server/R2015a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version CXXABI_1.3.8 not found (required by /usr/lib/x86_64-linux-gnu/libgflags.so.2)

2. 解決方案：

sudo ln -sf /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/local/MATLAB/MATLAB_Production_Server/R2015a/bin/glnxa64/libstdc++.so.6
